How to Fix CVE-2022-3269

To remediate this vulnerability, upgrade all affected Rdiffweb dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

rdiffweb fixed: 2.4.7 
pip install rdiffweb>=2.4.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show rdiffweb

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-3269, inspect your installed packages using pip:

pip show rdiffweb

Analyze the terminal output to locate any version of Rdiffweb in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.7), your application is affected.

Note: The pip show rdiffweb command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. In Rdiffweb, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

rdiffweb prior to 2.4.7 fails to invalidate session cookies on logout, leading to session fixation and allowing an attacker to access a users account. After logging in and logging out, the application continues to use the preauthentication cookies. The cookies remain the same after closing the browser and after password reset. The same cookies are reassigned for additional user logins which can lead to session fixation. An attacker can gain unauthorized access to the account of users who are using the same browser as long as a single session cookie persists on that browser once the attacker obtains a session cookie through another attack. This issue is patched in version 2.4.7. There are no known workarounds.
