This vulnerability allows Cross-Site Request Forgery (CSRF) in Oren Yomtov's Mass Custom Fields Manager, which subsequently permits reflected cross-site scripting (XSS). The vulnerability has been assigned a high severity rating with a CVSS score of 7.1, indicating a significant potential impact on affected systems. The vulnerability affects versions of the Mass Custom Fields Manager plugin up to 1.5.
Risk to organizations includes the potential for attackers to exploit this vulnerability to execute scripts in the context of a user's browser, leading to unauthorized actions or data exposure. Given the nature of CSRF attacks, user interaction is required, as the attack typically requires the victim to be tricked into clicking a link while logged into a vulnerable application.
As of now, there are no known public exploits or proofs of concept available. However, the urgency for defenders is high, as failure to patch could leave organizations exposed to potential attacks. Organizations using the affected plugin should prioritize patching immediately.
The vulnerability was published on January 16, 2025, and its status is currently marked as deferred. Organizations should remain vigilant and monitor for any updates regarding this vulnerability.
Vulnerability Details
The Cross-Site Request Forgery vulnerability in the Oren Yomtov Mass Custom Fields Manager allows for reflected XSS. The CVSS score of 7.1 indicates a high severity, which can lead to significant impacts on confidentiality, integrity, and availability, although the overall impact is assessed as low due to the requirement of user interaction.
This vulnerability falls under CWE-352 (Cross-Site Request Forgery), which highlights the risk posed by lack of proper validation of user requests in web applications. The plugin versions affected by this vulnerability are all versions up to and including 1.5.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of user requests. Attackers may leverage this flaw by crafting malicious requests that can be executed by authorized users without their consent. The attack vector is network-based, and the complexity is considered low, making it easier for attackers to exploit.
No privileges are required to exploit this vulnerability, but user interaction is necessary. The impacts on confidentiality, integrity, and availability are all assessed as low, indicating that while the attack can be executed, the effects may not be catastrophic without additional vulnerabilities or weaknesses.
Risk & Impact Analysis
Organizations using the affected Mass Custom Fields Manager plugin face a serious risk if they do not address this vulnerability. The potential blast radius includes any users who interact with the application while logged in. Attackers may exploit this vulnerability to perform unauthorized actions on behalf of legitimate users.
Given the CVSS score of 7.1, the urgency is high. Organizations should address this vulnerability in their priority patch cycle to mitigate risk. The lack of public exploits does not diminish the need for immediate action, as attackers can develop new methods of exploiting such vulnerabilities.
