Description

Camaleon CMS 0.1.7 to 2.6.0 doesn’t terminate the active session of the users, even after the admin changes the user’s password. A user that was already logged in, will still have access to the application even after the password was changed.

Technical Analysis

CVE-2021-25970 is a high-severity vulnerability affecting Camaleon CMS versions 0.1.7 through 2.6.0. The core issue is insufficient session expiration, classified under CWE-613. Specifically, when an administrator changes a user's password, the system fails to terminate any active sessions associated with that user. This means that a user who was previously authenticated and logged in can continue to access the application without re-authenticating, even after their password has been changed. This behavior undermines the security principle that password changes should invalidate existing sessions to prevent unauthorized access. The vulnerability allows an attacker or unauthorized user who has gained access to a session token or is currently logged in to maintain access despite password resets, potentially leading to unauthorized data access, privilege escalation, or persistent unauthorized control over the CMS. The CVSS v3.1 base score is 8.8 (high), reflecting the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R), with impact on confidentiality, integrity, and availability all rated high (C:H/I:H/A:H). The scope remains unchanged (S:U). There are no known public exploits in the wild, and no official patches linked in the provided data, indicating that mitigation may require manual intervention or updates from the vendor. The vulnerability is particularly critical for environments where session management is relied upon for security post-password changes, such as multi-user CMS deployments.

Potential Impact

For European organizations using Camaleon CMS, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web content management systems. Attackers or malicious insiders could maintain unauthorized access even after password resets, potentially leading to data breaches, defacement, or unauthorized administrative actions. This is especially concerning for organizations handling sensitive or regulated data, such as those in finance, healthcare, or government sectors. The persistence of active sessions despite password changes undermines incident response efforts, as revoking credentials alone will not prevent continued access. This could facilitate lateral movement within networks or prolonged unauthorized presence. Given the CMS's role in managing web content, exploitation could also impact brand reputation and compliance with European data protection regulations like GDPR if personal data is exposed or manipulated. Additionally, the ease of exploitation (no privileges required and low complexity) increases the likelihood of successful attacks if the system is internet-facing.

Mitigation Recommendations

1. Immediate mitigation should include manual invalidation of all active sessions upon password changes. This can be implemented by modifying the session management logic to track and revoke sessions tied to a user when their credentials are updated. 2. Organizations should monitor active sessions and implement session timeout policies that limit session duration and require re-authentication periodically. 3. Deploy Web Application Firewalls (WAFs) with rules to detect anomalous session behaviors or repeated access patterns from the same session tokens. 4. Restrict administrative access to trusted networks or VPNs to reduce exposure. 5. Regularly audit user sessions and access logs to detect suspicious activity. 6. Engage with the Camaleon CMS community or vendor to obtain patches or updates addressing this vulnerability; if unavailable, consider upgrading to a version where this issue is resolved or migrating to alternative CMS platforms with robust session management. 7. Educate administrators and users about the risks of session persistence and enforce multi-factor authentication (MFA) to add an additional layer of security beyond passwords. 8. Implement security monitoring tools that can alert on unusual session persistence or concurrent sessions from different locations for the same user.
