The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. This vulnerability allows unauthenticated attackers to change arbitrary users' passwords, including those of administrators, due to the plugin not properly validating a user's identity prior to updating their password. The severity of this vulnerability is critical, with a CVSS score of 9.8, indicating that it poses a significant risk to organizations using the affected plugin.
Risk to organizations includes potential unauthorized access to sensitive accounts and data breaches. Given the critical nature of this vulnerability, organizations should prioritize patching immediately. The exploitability score is noted as critical, emphasizing the urgency for organizations to address this issue.
Currently, there are no known public exploits or proof-of-concept (PoC) available for this vulnerability. However, the nature of the weakness indicates that it could be easily exploited by attackers with malicious intent. Therefore, organizations need to remain vigilant and proactive in addressing this vulnerability.
As this vulnerability is critical, organizations using the s2Member plugin should be aware of the potential impact and take necessary actions to secure their environments.
Vulnerability Details
The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. The vulnerability is caused by the plugin not validating a user's identity properly before updating their password. This inadequacy allows unauthenticated attackers to change arbitrary users' passwords, including those of administrators, enabling them to leverage this access to gain control of those accounts.
The CVSS score for this vulnerability is 9.8, categorizing it as critical. This high score reflects the ease of exploitation and the potential impact on confidentiality, integrity, and availability of the affected systems.
The vulnerability is classified under CWE-269, which indicates a failure to properly validate user input. Organizations should consider this classification when assessing the security posture of their applications.
Technical Analysis
The root cause of this vulnerability lies in the failure of the s2Member plugin to validate a user's identity before allowing password updates. This oversight means that attackers can exploit the system without needing any privileges or user interaction, making it a low complexity attack. The attack vector is classified as network-based, allowing for remote exploitation.
Since this vulnerability requires no privileges and no user interaction to exploit, the confidentiality, integrity, and availability impacts are all rated as high. Attackers may leverage this vulnerability to gain unauthorized access to administrative accounts, leading to significant risks for organizations.
Risk & Impact Analysis
Organizations using the s2Member plugin are at a substantial risk due to this critical vulnerability. If exploited, attackers can gain access to sensitive user accounts, potentially leading to unauthorized actions within the WordPress environment. The blast radius of this vulnerability is extensive, as it affects all users of the plugin, including administrators.
Given the CVSS score of 9.8, organizations should address this vulnerability in their priority patch cycle. The potential for data breaches and unauthorized access to critical systems necessitates immediate attention to mitigate risks.
