A high-severity Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Ederson Peka Unlimited Page Sidebars plugin, specifically affecting versions from n/a through 0.2.6. This vulnerability allows for stored XSS attacks, which can lead to unauthorized actions performed on behalf of the victim user, presenting significant risks to organizations that utilize this plugin.
The CVSS score for this vulnerability is 7.1, categorizing it as high severity. Given the nature of CSRF attacks, the potential for exploitation is concerning, especially since the attack vector is over the network and requires user interaction. Organizations must take this threat seriously as it could lead to data leakage or unauthorized administrative actions.
Currently, this vulnerability is classified as deferred, indicating that while it is recognized, there may be no immediate action required. However, organizations should not become complacent, as the lack of immediate patching could expose them to higher risks.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The attack complexity is low, and the implications of a successful attack can be severe, making it critical to address this issue promptly.
Vulnerability Details
The vulnerability allows for Cross-Site Request Forgery (CSRF) due to inadequate verification of user requests in the Ederson Peka Unlimited Page Sidebars plugin. This issue affects all versions up to and including 0.2.6.
The CVSS score of 7.1 signifies high severity, with the following metrics: attack vector (network), attack complexity (low), privileges required (none), and user interaction required (yes). The impact on confidentiality, integrity, and availability is rated as low.
The vulnerability falls under CWE-352, which refers to Cross-Site Request Forgery. This classification highlights the potential for unauthorized actions to be executed on behalf of legitimate users.
Technical Analysis
The root cause of this vulnerability lies in the insufficient validation of requests sent to the server. Attackers may leverage CSRF techniques to exploit this weakness, allowing them to perform actions without the explicit consent of the user. The attack vector is categorized as network-based, indicating that it can be executed remotely.
The attack complexity is low, meaning that no specialized knowledge is required to exploit the vulnerability. Additionally, the requirement for user interaction means that the user must be tricked into performing an action, such as clicking a malicious link.
The potential impact on confidentiality, integrity, and availability is categorized as low, indicating that while the effects may not be catastrophic, they could still lead to unauthorized data exposure or manipulation.
Risk & Impact Analysis
Risk to organizations includes exposure to unauthorized actions being performed on behalf of users, which could lead to data breaches or loss of sensitive information. The blast radius for this vulnerability is significant, especially for organizations that heavily rely on WordPress plugins for functionality.
Organizations should assess their environment to determine if they are using the affected version of the Unlimited Page Sidebars plugin. Given the high CVSS score, immediate attention is warranted to mitigate potential exploitation and protect user data.
The urgency for remediation is high, as the potential for exploitation is present, and the user interaction requirement does not significantly hinder the ability for attackers to leverage this vulnerability.
