An issue was discovered in the flaskcode package through 0.0.8 for Python. An unauthenticated directory traversal, exploitable with a POST request to a /update-resource-data/<file_path> URI (from views.py), allows attackers to write to arbitrary files.

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize() and equal() functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications that normalize or compare attacker-controlled URLs to enforce path-based policy can be bypassed, with a path that appears confined under an allowed prefix normalizing to a different location. Versions <= 3.1.0 are affected. Update to 3.1.1 or later.

Synapse is a package for Matrix homeservers written in Python 3/Twisted. Prior to version 1.47.1, Synapse instances with the media repository enabled can be tricked into downloading a file from a remote server into an arbitrary directory. No authentication is required for the affected endpoint. The last 2 directories and file name of the path are chosen randomly by Synapse and cannot be controlled by an attacker, which limits the impact. Homeservers with the media repository disabled are unaffected. Homeservers with a federation whitelist are also unaffected, since Synapse will check the remote hostname, including the trailing `../`s, against the whitelist. Server administrators should upgrade to 1.47.1 or later. Server administrators using a reverse proxy could, at the expense of losing media functionality, may block the certain endpoints as a workaround. Alternatively, non-containerized deployments can be adapted to use the hardened systemd config.

HwPCAssistant has a Improper Input Validation vulnerability.Successful exploitation of this vulnerability may create any file with the system app permission.

A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

A path traversal vulnerability in the Moxa MXview Network Management software Versions 3.x to 3.2.2 may allow an attacker to create or overwrite critical files used to execute code, such as programs or libraries.

Directory traversal can occur in the Basecamp com.basecamp.bc3 application before 4.2.1 for Android, which may allow an attacker to write arbitrary files in the application's private directory. Additionally, by using a malicious intent, the attacker may redirect the server's responses (containing sensitive information) to third-party applications by using a custom-crafted deeplink scheme.

SeaCMS 6.64 and 7.2 allows remote attackers to delete arbitrary files via the filedir parameter.

Minecraft before 1.17.1, when online-mode=false is configured, allows path traversal for deletion of arbitrary JSON files.

The use of the deprecated API `process.binding()` can bypass the permission model through path traversal. This vulnerability affects all users using the experimental permission model in Node.js 20.x. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.

Firefox normally asks for confirmation before asking the operating system to find an application to handle a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an unscrupulous program that the user downloaded could register itself as a handler. The website that served the application download could then launch that application at will. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, and Firefox ESR < 115.15.

An attacker could utilize a function in MDT AutoSave versions prior to v6.02.06 that permits changing a designated path to another path and traversing the directory, allowing the replacement of an existing file with a malicious file.

tar/TarFileReader.cpp in Cauldron cbang before bastet-v8.1.17 has a directory traversal during extraction that allows the attacker to create or write to files outside the current directory via a crafted tar archive.

The Code Extension Marketplace is an open-source alternative to the VS Code Marketplace. Prior to 2.4.2, Zip Slip vulnerability in coder/code-marketplace allowed a malicious VSIX file to write arbitrary files outside the extension directory. ExtractZip passed raw zip entry names to a callback that wrote files via filepath.Join with no boundary check; filepath.Join resolved .. components but did not prevent the result from escaping the base path. This vulnerability is fixed in 2.4.2.

Pimcore is an open source data and experience management platform. Versions of Pimcore prior to 10.5.18 are vulnerable to path traversal. The impact of this path traversal and arbitrary extension is limited to creation of arbitrary files and appending data to existing files. When combined with the SQL Injection, the exported data `RESTRICTED DIFFUSION 9 / 9` can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary PHP code on the server with the permissions of the webserver. Users may upgrade to version 10.5.18 to receive a patch or, as a workaround, apply the patch manually.

mindsdb is a Machine Learning platform to help developers build AI solutions. In affected versions an unsafe extraction is being performed using `tarfile.extractall()` from a remotely retrieved tarball. Which may lead to the writing of the extracted files to an unintended location. Sometimes, the vulnerability is called a TarSlip or a ZipSlip variant. An attacker may leverage this vulnerability to overwrite any local file which the server process has access to. There is no risk of file exposure with this vulnerability. This issue has been addressed in release `23.2.1.0 `. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Flatpak is a Linux application sandboxing and distribution framework. Prior to 1.16.4, the caching for ld.so removes outdated cache files without properly checking that the app controlled path to the outdated cache is in the cache directory. This allows Flatpak apps to delete arbitrary files on the host. This vulnerability is fixed in 1.16.4.

The File Repository Server (FRS) CORBA listener in SAP BussinessObjects Edge 4.0 allows remote attackers to write to arbitrary files via a full pathname, aka SAP Note 2018681.

Halloy is an IRC application written in Rust. Prior to commit 0f77b2cfc5f822517a256ea5a4b94bad8bfe38b6, the DCC receive flow did not sanitize filenames from incoming `DCC SEND` requests. A remote IRC user could send a filename with path traversal sequences like `../../.ssh/authorized_keys` and the file would be written outside the user's configured `save_directory`. With auto-accept enabled this required zero interaction from the victim. Starting with commit 0f77b2cfc5f822517a256ea5a4b94bad8bfe38b6, all identified code paths sanitize filenames through a shared `sanitize_filename` function.

Junrar is an open source java RAR archive library. Prior to version 7.5.10, a path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content into sibling directories when a crafted RAR archive is extracted. Version 7.5.10 fixes the issue.

Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows remote attackers to write arbitrary files via unspecified vectors.

A relative path traversal vulnerability has been reported to affect QNAP NAS running QTS and QuTS hero. If exploited, this vulnerability allows attackers to modify files that impact system integrity. QNAP have already fixed this vulnerability in the following versions: QTS 4.5.2.1630 Build 20210406 and later QTS 4.3.6.1663 Build 20210504 and later QTS 4.3.3.1624 Build 20210416 and later QuTS hero h4.5.2.1638 Build 20210414 and later QNAP NAS running QTS 4.5.3 are not affected.

In Ruby through 3.0 on Windows, a remote attacker can submit a crafted path when a Web application handles a parameter with TmpDir.

A Directory Traversal vulnerability exists in the GNU patch before 2.7.4. A remote attacker can write to arbitrary files via a symlink attack in a patch file. NOTE: this issue exists because of an incomplete fix for CVE-2015-1196.

bit7z is a cross-platform C++ static library that allows the compression/extraction of archive files. Prior to version 4.0.11, a path traversal vulnerability ("Zip Slip") exists in bit7z's archive extraction functionality. The library does not adequately validate file paths contained in archive entries, allowing files to be written outside the intended extraction directory through three distinct mechanisms: relative path traversal, absolute path traversal, and symbolic link traversal. An attacker can exploit this by providing a malicious archive to any application that uses bit7z to extract untrusted archives. Successful exploitation results in arbitrary file write with the privileges of the process performing the extraction. This could lead to overwriting of application binaries, configuration files, or other sensitive data. The vulnerability does not directly enable reading of file contents; the confidentiality impact is limited to the calling application's own behavior after extraction. However, applications that subsequently serve or display extracted files may face secondary confidentiality risks from attacker-created symlinks. Fixes have been released in version 4.0.11. If upgrading is not immediately possible, users can mitigate the vulnerability by validating each entry's destination path before writing. Other mitigations include running extraction with least privilege and extracting untrusted archives in a sandboxed directory.

NiceGUI is a Python-based UI framework. Prior to 3.7.0, NiceGUI's FileUpload.name property exposes client-supplied filename metadata without sanitization, enabling path traversal when developers use the pattern UPLOAD_DIR / file.name. Malicious filenames containing ../ sequences allow attackers to write files outside intended directories, with potential for remote code execution through application file overwrites in vulnerable deployment patterns. This design creates a prevalent security footgun affecting applications following common community patterns. Note: Exploitation requires application code incorporating file.name into filesystem paths without sanitization. Applications using fixed paths, generated filenames, or explicit sanitization are not affected. This vulnerability is fixed in 3.7.0.

Git is a revision control system. Prior to versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1, by feeding specially crafted input to `git apply --reject`, a path outside the working tree can be overwritten with partially controlled contents (corresponding to the rejected hunk(s) from the given patch). A fix is available in versions 2.30.9, 2.31.8, 2.32.7, 2.33.8, 2.34.8, 2.35.8, 2.36.6, 2.37.7, 2.38.5, 2.39.3, and 2.40.1. As a workaround, avoid using `git apply` with `--reject` when applying patches from an untrusted source. Use `git apply --stat` to inspect a patch before applying; avoid applying one that create a conflict where a link corresponding to the `*.rej` file exists.

Python-Multipart is a streaming multipart parser for Python. Prior to version 0.0.22, a Path Traversal vulnerability exists when using non-default configuration options `UPLOAD_DIR` and `UPLOAD_KEEP_FILENAME=True`. An attacker can write uploaded files to arbitrary locations on the filesystem by crafting a malicious filename. Users should upgrade to version 0.0.22 to receive a patch or, as a workaround, avoid using `UPLOAD_KEEP_FILENAME=True` in project configurations.

Git, a revision control system, is vulnerable to path traversal prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8. By feeding a crafted input to `git apply`, a path outside the working tree can be overwritten as the user who is running `git apply`. A fix has been prepared and will appear in v2.39.2, v2.38.4, v2.37.6, v2.36.5, v2.35.7, v2.34.7, v2.33.7, v2.32.6, v2.31.7, and v2.30.8. As a workaround, use `git apply --stat` to inspect a patch before applying; avoid applying one that creates a symbolic link and then creates a file beyond the symbolic link.

Rapid7 Insight Agent token handler versions 3.2.6 and below, suffer from a Directory Traversal vulnerability whereby unsanitized input from a CLI argument flows into io.ioutil.WriteFile, where it is used as a path. This can result in a Path Traversal vulnerability and allow an attacker to write arbitrary files. This issue is remediated in version 3.3.0 via safe guards that reject inputs that attempt to do path traversal.

NiceGUI is a Python-based UI framework. Prior to 3.10.0, Since PurePosixPath only recognizes forward slashes (/) as path separators, an attacker can bypass this sanitization on Windows by using backslashes (\) in the upload filename. Applications that construct file paths using file.name (a pattern demonstrated in NiceGUI's bundled examples) are vulnerable to arbitrary file write on Windows. This vulnerability is fixed in 3.10.0.

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.1, the Matches() function in rules/rules.go uses strings.HasPrefix() without a trailing directory separator when matching paths against access rules. A rule for /uploads also matches /uploads_backup/, granting or denying access to unintended directories. This vulnerability is fixed in 2.63.1.

SiYuan is a personal knowledge management system. Prior to version 3.1.16, the `/api/asset/upload` endpoint in Siyuan is vulnerable to both arbitrary file write to the host and stored cross-site scripting (via the file write). Version 3.1.16 contains a patch for the issue.

: Relative Path Traversal vulnerability in B&R Industrial Automation Automation Studio allows Relative Path Traversal.This issue affects Automation Studio: from 4.0 through 4.12.

Initialization of a resource with an insecure default vulnerability exists in SD-330AC and AMC Manager provided by silex technology, Inc. When the affected device is connected to the network with the initial (factory-default) configuration, the device can be configured with the null string password.

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to conduct directory traversal attacks and overwrite certain files that should be restricted on an affected system. These vulnerabilities are due to insufficient input validation. An attacker could exploit these vulnerabilities by using the web-based management interface to upload a file to location on an affected device that they should not have access to. A successful exploit could allow the attacker to overwrite files on the file system of the affected device.

Romeo gives the capability to reach high code coverage of Go ≥1.20 apps by helping to measure code coverage for functional and integration tests within GitHub Actions. Prior to version 0.2.2, the `sanitizeArchivePath` function in `webserver/api/v1/decoder.go` (lines 80-88) is vulnerable to a path traversal bypass due to a missing trailing path separator in the `strings.HasPrefix` check. A crafted tar archive can write files outside the intended destination directory. Version 0.2.2 fixes the issue.

FileRise is a self-hosted web file manager / WebDAV server. In versions prior to 3.9.0, a hardcoded default encryption key (default_please_change_this_key) is used for all cryptographic operations — HMAC token generation, AES config encryption, and session tokens — allowing any unauthenticated attacker to forge upload tokens for arbitrary file upload to shared folders, and to decrypt admin configuration secrets including OIDC client secrets and SMTP passwords. FileRise uses a single key (PERSISTENT_TOKENS_KEY) for all crypto operations. The default value default_please_change_this_key is hardcoded in two places and used unless the deployer explicitly overrides the environment variable. This issue is fixed in version 3.9.0.

Black is the uncompromising Python code formatter. Prior to 26.3.1, Black writes a cache file, the name of which is computed from various formatting options. The value of the --python-cell-magics option was placed in the filename without sanitization, which allowed an attacker who controls the value of this argument to write cache files to arbitrary file system locations. Fixed in Black 26.3.1.

Active Debug Code vulnerability in Mitsubishi Electric Corporation MELSEC WS Series WS0-GETH00200 Serial number 2310 **** and prior allows a remote unauthenticated attacker to bypass authentication and illegally log into the affected module by connecting to it via telnet which is hidden function and is enabled by default when shipped from the factory. As a result, a remote attacker with unauthorized login can reset the module, and if certain conditions are met, he/she can disclose or tamper with the module's configuration or rewrite the firmware.

An issue was discovered in SmartClient 12.0. The Remote Procedure Call (RPC) saveFile provided by the console functionality on the /tools/developerConsoleOperations.jsp (or /isomorphic/IDACall) URL allows an unauthenticated attacker to overwrite files via vectors involving an XML comment and /.. path traversal.

Nginx UI is a web user interface for the Nginx web server. Nginx UI v2.0.0-beta.35 and earlier gets the value from the json field without verification, and can construct a value value in the form of `../../`. Arbitrary files can be written to the server, which may result in loss of permissions. Version 2.0.0-beta.26 fixes the issue.
