CVE-2022-3327 is a Missing Authentication for Critical Function vulnerability discovered in GitHub repository ikus060/rdiffweb prior to version 2.5.0a6. The vulnerability was disclosed in October 2022 and affects all versions of rdiffweb up to version 2.4.10 and alpha versions up to 2.5.0a5 (NVD).

The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. The vulnerability is classified as CWE-306 (Missing Authentication for Critical Function). This indicates that the vulnerability is network accessible, requires low attack complexity, needs no privileges, and can result in high impacts to confidentiality, integrity, and availability (NVD).

The vulnerability could allow attackers to access critical functions without proper authentication, potentially leading to unauthorized access to sensitive data, system manipulation, and compromise of system integrity. The high CVSS score indicates severe potential consequences if the vulnerability is exploited (NVD).

The vulnerability has been patched by defining idle and absolute session timeout with aggressive defaults to protect usage on public computers. Users should upgrade to rdiffweb version 2.5.0a6 or later. The fix includes implementation of session idle timeout (default 10 minutes) and absolute session timeout (default 20 minutes) (GitHub Commit).
