CWE-940
Improper Verification of Source of a Communication Channel
The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.
CVE-2025-23222 (GCVE-0-2025-23222)
Vulnerability from cvelistv5 – Published: 2025-01-24 00:00 – Updated: 2025-02-12 20:41

Summary
An issue was discovered in Deepin dde-api-proxy through 1.0.19 in which unprivileged users can access D-Bus services as root. Specifically, dde-api-proxy runs as root and forwards messages from arbitrary local users to legacy D-Bus methods in the actual D-Bus services, and the actual D-Bus services don't know about the proxy situation (they believe that root is asking them to do things). Consequently several proxied methods, that shouldn't be accessible to non-root users, are accessible to non-root users. In situations where Polkit is involved, the caller would be treated as admin, resulting in a similar escalation of privileges.

CVE-2025-25305 (GCVE-0-2025-25305)
Vulnerability from cvelistv5 – Published: 2025-02-18 18:53 – Updated: 2025-02-18 19:23

Title
SSL validation for outgoing requests in Home Assistant Core and used libs not correct
Summary
Home Assistant Core is an open source home automation that puts local control and privacy first. Affected versions are subject to a potential man-in-the-middle attacks due to missing SSL certificate verification in the project codebase and used third-party libraries. In the past, `aiohttp-session`/`request` had the parameter `verify_ssl` to control SSL certificate verification. This was a boolean value. In `aiohttp` 3.0, this parameter was deprecated in favor of the `ssl` parameter. Only when `ssl` is set to `None` or provided with a correct configured SSL context the standard SSL certificate verification will happen. When migrating integrations in Home Assistant and libraries used by Home Assistant, in some cases the `verify_ssl` parameter value was just moved to the new `ssl` parameter. This resulted in these integrations and 3rd party libraries using `request.ssl = True`, which unintentionally turned off SSL certificate verification and opened up a man-in-the-middle attack vector. This issue has been addressed in version 2024.1.6 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2025-40820 (GCVE-0-2025-40820)
Vulnerability from cvelistv5 – Published: 2025-12-09 10:44 – Updated: 2025-12-09 15:55
VLAI
Summary
Affected products do not properly enforce TCP sequence number validation in specific scenarios but accept values within a broad range. This could allow an unauthenticated remote attacker e.g. to interfere with connection setup, potentially leading to a denial of service. The attack succeeds only if an attacker can inject IP packets with spoofed addresses at precisely timed moments, and it affects only TCP-based services.

Title
Insufficiently Secure Hostname Verification for Outbound TLS Connections in SAP NetWeaver Application Server Java
Summary
The widely used component that establishes outbound TLS connections in SAP NetWeaver Application Server Java does not reliably match the hostname that is used for the connection against the wildcard hostname defined in the received certificate of remote TLS server. This might lead to the outbound connection being established to a possibly malicious remote TLS server and hence disclose information. Integrity and Availability are not impacted.

CVE-2025-59159 (GCVE-0-2025-59159)

Title
SillyTavern Web Interface Vulnerable to DNS Rebinding
Summary
SillyTavern is a locally installed user interface that allows users to interact with text generation large language models, image generation engines, and text-to-speech voice models. In versions prior to 1.13.4, the web user interface for SillyTavern is susceptible to DNS rebinding, allowing attackers to perform actions like install malicious extensions, read chats, inject arbitrary HTML for phishing attacks, etc. The vulnerability has been patched in the version 1.13.4 by introducing a server configuration setting that enables a validation of host names in inbound HTTP requests according to the provided list of allowed hosts: `hostWhitelist.enabled` in config.yaml file or `SILLYTAVERN_HOSTWHITELIST_ENABLED` environment variable. While the setting is disabled by default to honor a wide variety of existing user configurations and maintain backwards compatibility, existing and new users are encouraged to review their server configurations and apply necessary changes to their setup, especially if hosting over the local network while not using SSL.

Mitigation
Phase: Architecture and Design
Description:
- Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.
- When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
CAPEC-500: WebView Injection
An adversary, through a previously installed malicious application, injects code into the context of a web page displayed by a WebView component. Through the injected code, an adversary is able to manipulate the DOM tree and cookies of the page, expose sensitive information, and can launch attacks against the web application from within the web page.
CAPEC-594: Traffic Injection
An adversary injects traffic into the target's network connection. The adversary is therefore able to degrade or disrupt the connection, and potentially modify the content. This is not a flooding attack, as the adversary is not focusing on exhausting resources. Instead, the adversary is crafting a specific input to affect the system in a particular way.
CAPEC-595: Connection Reset
In this attack pattern, an adversary injects a connection reset packet to one or both ends of a target's connection. The attacker is therefore able to have the target and/or the destination server sever the connection without having to directly filter the traffic between them.
CAPEC-596: TCP RST Injection
An adversary injects one or more TCP RST packets to a target after the target has made a HTTP GET request. The goal of this attack is to have the target and/or destination web server terminate the TCP connection.
