CVE-2022-29450 is a medium-severity security vulnerability classified as CWE-352, which refers to Cross-Site Request Forgery (CSRF) attacks, found in the Admin Management Xtended WordPress plugin developed by Oliver Schlöbe. This plugin, widely used to enhance administrative capabilities within WordPress environments, contains multiple CSRF vulnerabilities in versions up to and including 2.4.4. CSRF vulnerabilities allow an attacker to trick authenticated users into unknowingly executing unwanted actions on a web application in which they are currently authenticated. In this case, an attacker could craft malicious requests that, when executed by an authenticated administrator or user with sufficient privileges, could lead to unauthorized changes in the WordPress administrative interface or plugin settings. The vulnerability arises because the plugin fails to implement proper anti-CSRF tokens or other verification mechanisms to confirm the legitimacy of requests that modify state or perform sensitive operations. Although no known exploits have been reported in the wild, the presence of multiple CSRF flaws increases the attack surface and risk. Exploitation requires the victim to be authenticated and to interact with a maliciously crafted link or webpage, which then triggers unauthorized actions within the vulnerable plugin. The lack of available patches or updates at the time of reporting further exacerbates the risk for affected installations. Given WordPress’s widespread use across Europe for websites ranging from small businesses to large enterprises, this vulnerability poses a tangible risk to the integrity and security of affected sites.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites for critical business functions, e-commerce, or public-facing services. Successful exploitation could lead to unauthorized administrative actions such as changing plugin configurations, modifying user roles, or altering site content, potentially resulting in data integrity issues, service disruption, or reputational damage. Since CSRF attacks exploit authenticated sessions, organizations with insufficient session management or lacking multi-factor authentication are at higher risk. The vulnerability could also be leveraged as a foothold for further attacks, including privilege escalation or injection of malicious content, which could compromise customer data or lead to regulatory non-compliance under GDPR. The absence of known exploits suggests the threat is currently theoretical but should be treated proactively to prevent future incidents. The medium severity rating indicates moderate risk but with potential for serious consequences if exploited in targeted attacks against high-value European targets.

To mitigate this vulnerability, European organizations should take the following specific actions beyond generic advice: 1) Immediately audit all WordPress installations for the presence of the Admin Management Xtended plugin and identify versions at or below 2.4.4. 2) If an updated, patched version becomes available, prioritize prompt plugin updates to remediate the CSRF flaws. 3) In the absence of patches, implement web application firewall (WAF) rules to detect and block suspicious POST requests or CSRF attack patterns targeting the plugin’s endpoints. 4) Enforce strict user session management, including short session timeouts and mandatory re-authentication for sensitive administrative actions. 5) Deploy Content Security Policy (CSP) headers and SameSite cookie attributes to reduce the risk of CSRF exploitation. 6) Educate administrators and users about the risks of clicking untrusted links while logged into WordPress admin panels. 7) Monitor logs for unusual administrative activity that could indicate attempted exploitation. 8) Consider temporarily disabling or replacing the plugin with alternative solutions if patching is not feasible. These targeted measures will help reduce the attack surface and protect critical WordPress environments from CSRF exploitation.
