CVE-2024-7053 Information

Description

A vulnerability in open-webui/open-webui version 0.3.8 allows an attacker with a user-level account to perform a session fixation attack. The session cookie for all users is set with the default SameSite=Lax and does not have the Secure flag enabled allowing the session cookie to be sent over HTTP to a cross-origin domain. An attacker can exploit this by embedding a malicious markdown image in a chat which when viewed by an administrator sends the admin’s session cookie to the attacker’s server. This can lead to a stealthy administrator account takeover potentially resulting in remote code execution (RCE) due to the elevated privileges of administrator accounts.
