Description
CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.9 and 2.11.4, session ids could be fixed by an attacker if the site is configured with server-side session storage (CKAN uses cookie-based session storage by default). The attacker would need to either set a cookie on the victim's browser or steal the victim's currently valid session. Session identifiers are now regenerated after each login. This vulnerability has been fixed in CKAN 2.10.9 and 2.11.4

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability in CKAN allows an attacker to fix a session ID if the site is configured with server-side session storage. The attacker can do this by setting a cookie on the victim's browser or stealing the victim's valid session. This means the attacker can hijack the victim's session. The issue has been fixed by regenerating session identifiers after each login in CKAN versions 2.10.9 and 2.11.4.


How can this vulnerability impact me? :

The vulnerability can lead to session fixation attacks, allowing an attacker to hijack a user's session. This can result in unauthorized access to the victim's account or data within the CKAN system, potentially compromising sensitive information.


What immediate steps should I take to mitigate this vulnerability?

Upgrade CKAN to version 2.10.9 or 2.11.4 or later, as these versions include a fix that regenerates session identifiers after each login, preventing session fixation attacks. Additionally, ensure that your CKAN installation is not configured to use server-side session storage, or if it is, take extra precautions to protect session cookies from being set or stolen by attackers.
