CVE-2024-10111: CWE-287 Improper Authentication in cyberlord92 OAuth Single Sign On – SSO (OAuth Client)
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 6.26.3. This is due to insufficient verification on the user being returned by the social login token. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the username and the user does not have an already-existing account for the service returning the token.
AI Analysis
Technical Summary
The OAuth Single Sign On – SSO (OAuth Client) plugin for WordPress suffers from an improper authentication vulnerability (CWE-287) that allows attackers to bypass authentication checks. This occurs because the plugin does not adequately verify the user identity returned by the social login token, enabling attackers who know a valid username to authenticate as that user without valid credentials. This affects all plugin versions up to and including 6.26.3. The vulnerability has a CVSS 3.1 base score of 8.1, indicating high severity with network attack vector, high impact on confidentiality, integrity, and availability, and no privileges or user interaction required.
Potential Impact
Successful exploitation allows unauthenticated attackers to log in as any existing user on the WordPress site, including administrators. This can lead to full site compromise, data exposure, unauthorized changes, and potential service disruption. The vulnerability undermines the authentication mechanism of the OAuth Single Sign On plugin, critically impacting site security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the plugin or disable it if possible to prevent exploitation. Monitor for updates from the vendor cyberlord92 and apply patches promptly once available.
