Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the email notification templates insert user-controlled device, geofence, and driver names into HTML email output without proper escaping. An attacker with low privileges can store crafted HTML in these fields, which is then rendered in notification emails sent to other users with access to the affected devices. This can lead to phishing or spoofed email content. This issue is fixed in version 6.13.0.

Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the KML and GPX export functionality writes device names to XML output without proper escaping. An attacker with low privileges can create a device with a crafted name that injects XML content into exported files. If another user exports and opens the affected KML or GPX file, this can corrupt the file structure and spoof exported location data. This issue is fixed in version 6.13.0.

Traccar is an open source GPS tracking system. In versions between 6.11.1 and 6.13.0, the CSV export functionality writes position data, including user-controlled device and computed attributes, to CSV output without proper escaping. An attacker can inject spreadsheet formulas through exported fields. When a manager or administrator opens the exported CSV file in spreadsheet software, this can cause formula execution and lead to command execution or data exfiltration. This has been patched in version 6.13.0.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users can steal OAuth 2.0 authorization codes by exploiting an open redirect vulnerability in two OIDC-related endpoints. The `redirect_uri` parameter is not validated against a whitelist, allowing attackers to redirect authorization codes to attacker-controlled URLs, enabling account takeover on any OAuth-integrated application. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system starting with 6.11.1 contain an issue in which authenticated users can execute arbitrary JavaScript in the context of other users' browsers by uploading malicious SVG files as device images. The application accepts SVG file uploads without sanitization and serves them with the `image/svg+xml` Content-Type, allowing embedded JavaScript to execute when victims view the image. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users who can create or edit devices can set a device `uniqueId` to an absolute path. When uploading a device image, Traccar uses that `uniqueId` to build the filesystem path without enforcing that the resolved path stays under the media root. This allows writing files outside the media directory. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain a Cross-Site WebSocket Hijacking (CSWSH) vulnerability in the `/api/socket` endpoint. The application fails to validate the `Origin` header during the WebSocket handshake. This allows a remote attacker to bypass the Same Origin Policy (SOP) and establish a full-duplex WebSocket connection using a legitimate user's credentials (JSESSIONID). As of time of publication, it is unclear whether a fix is available.

Traccar is an open source GPS tracking system. Default installs of Traccar on Windows between versions 6.1- 6.8.1 and non default installs between versions 5.8 - 6.0 are vulnerable to unauthenticated local file inclusion attacks which can lead to leakage of passwords or any file on the file system including the Traccar configuration file. Versions 5.8 - 6.0 are only vulnerable if <entry key='web.override'>./override</entry> is set in the configuration file. Versions 6.1 - 6.8.1 are vulnerable by default as the web override is enabled by default. The vulnerable code is removed in version 6.9.0.

Use of Default Credentials vulnerability in Tananaev Solutions Traccar Server on Administrator Panel modules allows Authentication Abuse.This issue affects the privileged transactions implemented by the Traccar solution that should otherwise be protected by the authentication mechanism.  These transactions could have an impact on any sensitive aspect of the platform, including Confidentiality, Integrity and Availability.

Traccar is an open source GPS tracking system. Traccar versions 5.1 through 5.12 allow arbitrary files to be uploaded through the device image upload API. Attackers have full control over the file contents, full control over the directory where the file is stored, full control over the file extension, and partial control over the file name. While it's not for an attacker to overwrite an existing file, an attacker can create new files with certain names and attacker-controlled extensions anywhere on the file system. This can potentially lead to remote code execution, XSS, DOS, etc. The default install of Traccar makes this vulnerability more severe. Self-registration is enabled by default, allowing anyone to create an account to exploit this vulnerability. Traccar also runs by default with root/system privileges, allowing files to be placed anywhere on the file system. Version 6.0 contains a fix for the issue. One may also turn off self-registration by default, as that would make most vulnerabilities in the application much harder to exploit by default and reduce the severity considerably.

Traccar is an open source GPS tracking system. Versions prior to 6.0 are vulnerable to path traversal and unrestricted upload of file with dangerous type. Since the system allows registration by default, attackers can acquire ordinary user permissions by registering an account and exploit this vulnerability to upload files with the prefix `device.` under any folder. Attackers can use this vulnerability for phishing, cross-site scripting attacks, and potentially execute arbitrary commands on the server. Version 6.0 contains a patch for the issue.

Traccar is an open source GPS tracking system. Prior to 5.11, Traccar is affected by an unrestricted file upload vulnerability in File feature allows attackers to execute arbitrary code on the server. This vulnerability is more prevalent because Traccar is recommended to run web servers as root user. It is also more dangerous because it can write or overwrite files in arbitrary locations. Version 5.11 was published to fix this vulnerability.

Traccar is an open source GPS tracking system. In Traccar before version 4.12 there is an unquoted Windows binary path vulnerability. Only Windows versions are impacted. Attacker needs write access to the filesystem on the host machine. If Java path includes a space, then attacker can lift their privilege to the same as Traccar service (system). This is fixed in version 4.12.

Traccar GPS Tracking System before version 4.9 has a LDAP injection vulnerability. It occurs when user input is being used in LDAP search filter. By providing specially crafted input, an attacker can modify the logic of the LDAP query and get admin privileges. The issue only impacts instances with LDAP configuration and where users can craft their own names. This has been patched in version 4.9.

In Traccar Server version 4.2, protocol/SpotProtocolDecoder.java might allow XXE attacks.

Traccar Traccar Server version 4.0 and earlier contains a CWE-94: Improper Control of Generation of Code ('Code Injection') vulnerability in ComputedAttributesHandler.java that can result in Remote Command Execution. This attack appear to be exploitable via Remote: web application request by a self-registered user. This vulnerability appears to have been fixed in 4.1 and later.
