CVE-2025-22769 is a medium-severity vulnerability classified as Cross-site Scripting (XSS), which allows attackers to perform stored XSS attacks in the Creative Brahma Multifox plugin. This issue has been identified as affecting Multifox versions from n/a through 1.3.7. The CVSS score of 6.5 indicates a moderate risk level, warranting attention from security teams.
The vulnerability arises from improper neutralization of input during web page generation. This allows attackers to inject malicious scripts that can be stored and subsequently executed within the context of a user's browser session. Given the network attack vector and low attack complexity, this vulnerability poses a risk to organizations utilizing the affected product.
Organizations should prioritize patching immediately to prevent potential exploitation, especially since user interaction is required to trigger the attack. The urgency to address this vulnerability is underscored by the potential impacts on confidentiality, integrity, and availability of web applications.
Currently, there are no known public exploits or proofs of concept available for this vulnerability. However, the deferred status indicates that it may still be relevant for organizations to assess their exposure and implement necessary mitigations.
Vulnerability Details
The official description outlines that this vulnerability allows for stored XSS attacks through improper neutralization of input during web page generation in Creative Brahma Multifox. The CVSS score of 6.5 is attributed to the following metrics: it has a network attack vector, low attack complexity, and requires low privileges with user interaction to exploit, changing the scope while impacting confidentiality, integrity, and availability.
The affected product is the Multifox plugin, with the vulnerability affecting versions up to 1.3.7. The vulnerability was published on January 15, 2025. It is classified under CWE-79, which pertains to improper neutralization of input in web applications.
Technical Analysis
The root cause of this vulnerability is the failure of the Multifox plugin to adequately sanitize user input during the generation of dynamic web content. Attackers may leverage this flaw to inject arbitrary JavaScript code into the web pages viewed by other users, leading to potential data theft or session hijacking.
The attack vector is classified as network-based, indicating that an attacker can exploit this vulnerability remotely. The complexity is low, making it easier for attackers to perform the attack without advanced skills. The privileges required are low, meaning that even users with minimal access can potentially trigger the vulnerability.
User interaction is required to exploit this vulnerability, as the malicious script must be executed in the context of the victim's browser. The impact on confidentiality, integrity, and availability is categorized as low, suggesting that while the risk exists, it may not lead to catastrophic failures but could still result in unauthorized access to sensitive information.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to user data, manipulation of session cookies, and the ability to perform actions on behalf of users without their consent. The stored XSS vulnerability can be particularly damaging because it allows attackers to execute scripts across multiple user sessions, significantly expanding the impact.
The urgency assessment, based on the CVSS score and current exploitation status, suggests that organizations should address this vulnerability in their priority patch cycle. Although it is not actively exploited, the potential for future attacks remains, making it crucial to apply recommended security measures.
