CVE-2022-3269: CWE-384 Session Fixation in ikus060 ikus060/rdiffweb
Session Fixation in GitHub repository ikus060/rdiffweb prior to 2.4.7.
AI Analysis
Technical Summary
CVE-2022-3269 is a session fixation vulnerability identified in the GitHub project ikus060/rdiffweb prior to version 2.4.7. The vulnerability is classified under CWE-384, which pertains to session fixation issues. Session fixation occurs when an attacker is able to fixate or set a user's session identifier (session ID) before the user logs in, allowing the attacker to hijack the authenticated session once the user authenticates. In this case, the vulnerability allows an attacker to force a victim to use a known session ID, which the attacker can then use to gain unauthorized access. The CVSS v3.0 base score is 6.4, indicating a medium severity level. The vector string (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L) shows that the attack can be performed remotely over the network, requires low privileges, no user interaction, but has high attack complexity. The impact on confidentiality is high, as the attacker can access sensitive information, while integrity and availability impacts are low. No known exploits are reported in the wild, and no official patch links are provided, but the issue was addressed in version 2.4.7 of rdiffweb. The vulnerability affects all unspecified versions prior to 2.4.7, meaning users running older versions are at risk. The root cause is improper session management that does not invalidate or regenerate session IDs upon authentication, allowing session fixation attacks.
Potential Impact
For European organizations using ikus060/rdiffweb, this vulnerability poses a significant risk to confidentiality of data managed or accessed via the application. Since rdiffweb is a web-based interface for rdiff-backup, which is used for remote backup and file synchronization, unauthorized access could lead to exposure of sensitive backup data, intellectual property, or personal data protected under GDPR. The medium severity rating suggests that while exploitation is not trivial due to high attack complexity, the lack of required user interaction and remote attack vector means attackers can attempt exploitation without user involvement. Organizations relying on rdiffweb for backup management could face data breaches, loss of trust, and regulatory penalties if exploited. The integrity and availability impacts are lower but still present, as attackers might manipulate backup data or disrupt backup operations. The absence of known exploits in the wild reduces immediate risk but does not eliminate it, especially if threat actors develop exploits targeting this vulnerability.
Mitigation Recommendations
European organizations should immediately verify the version of ikus060/rdiffweb in use and upgrade to version 2.4.7 or later where the vulnerability is fixed. If upgrading is not immediately possible, organizations should implement compensating controls such as enforcing strict session management policies, including regenerating session IDs upon authentication and invalidating old sessions. Network-level protections like web application firewalls (WAFs) can be configured to detect and block suspicious session fixation attempts. Additionally, monitoring and logging of session activities should be enhanced to detect anomalies indicative of session hijacking. Organizations should also review access controls and ensure that only authorized personnel have access to the rdiffweb interface, ideally restricting access via VPN or IP whitelisting. Regular security assessments and penetration testing focusing on session management can help identify residual risks. Finally, educating users about secure session practices and maintaining up-to-date software inventory are critical to prevent exploitation.
