A high-severity Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Pukhraj Suthar Simple Responsive Menu plugin. This vulnerability allows for Stored XSS, which can be exploited by attackers to execute malicious scripts within the context of a user's browser session. Risk to organizations includes potential unauthorized actions being taken on behalf of users, leading to compromised accounts and data exposure. The vulnerability affects all versions of the plugin up to and including 2.1.
The CVSS score for this vulnerability is 7.1, classifying it as high severity. This score reflects the potential for exploitation over a network, combined with a low attack complexity and the requirement for user interaction, which increases the likelihood of successful attacks. Organizations should prioritize patching immediately.
Currently, there is no public exploit confirmed. However, the nature of CSRF vulnerabilities means they can be particularly dangerous if not addressed swiftly. Organizations that utilize the Simple Responsive Menu plugin must schedule remediation as part of their security practices.
Given the persistent nature of CSRF vulnerabilities, it is critical for organizations to remain vigilant and ensure they implement necessary security measures to prevent exploitation.
Vulnerability Details
The vulnerability is classified under CWE-352, indicating it is a Cross-Site Request Forgery issue. The CVSS vector string is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, which details the attack vector as network-based, with a low complexity requirement and no privileges needed. User interaction is required, and the scope is changed, signaling that exploitation can impact other components.
The vulnerability was published on February 13, 2025, and its status is currently deferred. Organizations utilizing this plugin should be aware of the risks and prioritize the necessary updates.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of CSRF tokens within the plugin. Attackers may leverage this weakness to forge requests that can manipulate user data or settings without their consent. The attack vector is network-based, thus allowing an attacker to exploit this from a remote location, increasing the potential attack surface. The attack complexity is low since it does not require any sophisticated techniques.
In terms of privileges required, none are needed for the attacker to exploit this vulnerability. However, user interaction is necessary, meaning that the attacker must trick the user into performing an action that triggers the exploit. The impacts are classified as low for confidentiality, integrity, and availability, which indicates that while the risks are significant, they may not lead to catastrophic failures.
Risk & Impact Analysis
Real-world deployment risk associated with this vulnerability is substantial, particularly for organizations that rely on the Simple Responsive Menu plugin for user interfaces. If exploited, attackers can perform unauthorized actions on behalf of legitimate users, potentially leading to data breaches, unauthorized transactions, or further exploitation of the underlying system. The blast radius could extend to all users of the application, compromising user trust and leading to further security incidents.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. The urgency is driven not only by the severity of the vulnerability but also by the potential for widespread exploitation.
