A weakness has been identified in TRENDnet TEW-821DAP 1.12B01. This issue affects the function find_hwid/new_gui_update_firmware of the component Firmware Update Handler. Executing a manipulation of the argument dest can lead to insufficient verification of data authenticity. The attack can be launched remotely. Attacks of this nature are highly complex. The exploitability is assessed as difficult. The vendor explains: "That firmware version will only work on our hardware version v1.xR. We have already EOL that product 8 years ago and are no longer selling". This vulnerability only affects products that are no longer supported by the maintainer.

Client use of server error message in PostgreSQL allows a server not trusted under current SSL or GSS settings to furnish arbitrary non-NUL bytes to the libpq application. For example, a man-in-the-middle attacker could send a long error message that a human or screen-scraper user of psql mistakes for valid query results. This is probably not a concern for clients where the user interface unambiguously indicates the boundary between one error message and other text. Versions before PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21 are affected.

A vulnerability was determined in mkj Dropbear up to 2025.89. Impacted is the function unpackneg of the file src/curve25519.c of the component S Range Check.

The exploitability is considered difficult. The actual existence of this vulnerability is currently in question. Patch name: fdec3c90a15447bd538641d85e5a3e3ac981011d. To fix this issue, it is recommended to deploy a patch. The project maintainer explains: "Signature Malleability is not exploitable in SSH protocol. (...) [A] PoC doesn't exist for SSH implementation, but rather it's against the internal API."

This impacts the function mg_chacha20_poly1305_decrypt of the file /src/tls_chacha20.c of the component Poly1305 Authentication Tag Handler. The manipulation results in improper verification of cryptographic signature. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is said to be difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

The CMS Commander plugin for WordPress is vulnerable to authorization bypass due to the use of an insufficiently unique cryptographic signature on the 'cmsc_add_site' function in versions up to, and including, 2.287. This makes it possible for unauthenticated attackers to the plugin to change the '_cmsc_public_key' in the plugin config, providing access to the plugin's remote control functionalities, such as creating an admin access URL, which can be used for privilege escalation. This can only be exploited if the plugin has not been configured yet, however, if combined with another arbitrary plugin installation and activation vulnerability, the impact can be severe.

A weakness has been identified in D-Link DAP-2695 2.00RC13. The affected element is the function sub_40C6B8 of the component Firmware Update Handler. Executing manipulation can lead to improper verification of cryptographic signature. The attack can be launched remotely. Attacks of this nature are highly complex. The exploitability is described as difficult. The exploit has been made available to the public and could be exploited. This vulnerability only affects products that are no longer supported by the maintainer.

Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus' Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in 'enc_part' instead of the unencrypted version stored in 'ticket'. Use of the unencrypted version provides an opportunity for successful server impersonation and other attacks. NOTE: this CVE is only for Heimdal and other products that embed Heimdal code; it does not apply to other instances in which this part of the Kerberos 5 protocol specification is violated.

In webpack-subresource-integrity before version 1.5.1, all dynamically loaded chunks receive an invalid integrity hash that is ignored by the browser, and therefore the browser cannot validate their integrity. This removes the additional level of protection offered by SRI for such chunks. Top-level chunks are unaffected. This issue is patched in version 1.5.1.

Mids' Reborn Hero Designer 2.6.0.7 downloads the update manifest, as well as update files, over cleartext HTTP. Additionally, the application does not perform file integrity validation for files after download. An attacker can perform a man-in-the-middle attack against this connection and replace executable files with malicious versions, which the operating system then executes under the context of the user running Hero Designer.

An issue was discovered in OpenWrt 18.06.0 to 18.06.6 and 19.07.0, and LEDE 17.01.0 to 17.01.7. A bug in the fork of the opkg package manager before 2020-01-25 prevents correct parsing of embedded checksums in the signed repository index, allowing a man-in-the-middle attacker to inject arbitrary package payloads (which are installed without verification).

Hammer CLI, a CLI utility for Foreman, before version 0.10.0, did not explicitly set the verify_ssl flag for apipie-bindings that disable it by default. As a result the server certificates are not checked and connections are prone to man-in-the-middle attacks.

com.proxyman.NSProxy.HelperTool in Privileged Helper Tool in Proxyman for macOS 1.11.0 and earlier allows an attacker to change the System Proxy and redirect all traffic to an attacker-controlled computer, enabling MITM attacks.

Graylog is a free and open log management platform. Graylog makes use of only one single source port for DNS queries. Graylog binds a single socket for outgoing DNS queries and while that socket is bound to a random port number it is never changed again. This goes against recommended practice since 2008, when Dan Kaminsky discovered how easy is to carry out DNS cache poisoning attacks. In order to prevent cache poisoning with spoofed DNS responses, it is necessary to maximise the uncertainty in the choice of a source port for a DNS query. Although unlikely in many setups, an external attacker could inject forged DNS responses into a Graylog's lookup table cache. In order to prevent this, it is at least recommendable to distribute the DNS queries through a pool of distinct sockets, each of them with a random source port and renew them periodically. This issue has been addressed in versions 5.0.9 and 5.1.3. Users are advised to upgrade. There are no known workarounds for this issue.

UR+ (Universal Robots+) is a platform of hardware and software component sellers, for Universal Robots robots. When installing any of these components in the robots (e.g. in the UR10), no integrity checks are performed. Moreover, the SDK for making such components can be easily obtained from Universal Robots. An attacker could exploit this flaw by crafting a custom component with the SDK, performing Person-In-The-Middle attacks (PITM) and shipping the maliciously-crafted component on demand.

Cisco Webex Business Suite before 39.1.0 contains a vulnerability that could allow an unauthenticated, remote attacker to affect the integrity of the application. The vulnerability is due to improper validation of host header values. An attacker with a privileged network position, either a man-in-the-middle or by intercepting wireless network traffic, could exploit this vulnerability to manipulate header values sent by a client to the affected application. The attacker could cause the application to use input from the header to redirect a user from the Cisco Webex Meetings Online site to an arbitrary site of the attacker's choosing.

The vendor was contacted early about this disclosure but did not respond in any way.

The pc-kernel snap build process hardcoded the --allow-insecure-repositories and --allow-unauthenticated apt options when creating the build chroot environment. This could allow an attacker who is able to perform a MITM attack between the build environment and the Ubuntu archive to install a malicious package within the build chroot. This issue affects pc-kernel versions prior to and including 2019-07-16

It was found that in icedtea-web up to and including 1.7.2 and 1.8.2 executable code could be injected in a JAR file without compromising the signature verification. An attacker could use this flaw to inject code in a trusted JAR. The code would be executed inside the sandbox.

An issue in ClasroomIO before v.0.2.6 allows a remote attacker to escalate privileges via the endpoints /api/verify and /rest/v1/profile
