Description

The AIL Framework crawler task creation API (api_add_crawler_task) contained an insufficient authorization check when a user supplied a cookiejar UUID to attach to a one-shot or scheduled crawler task. The original code only verified that the cookiejar existed and, if its access level was 0, compared the cookiejar's owning user ID to the requesting user ID. It did not validate organizational boundaries, did not account for the requesting user's role. When the cookiejar level was not 0, no access check was performed at all. An authenticated user could therefore reference another organization's cookiejar by UUID and have the crawler use that organization's stored cookies (session tokens, authentication credentials) when performing web crawls, effectively leaking or exfiltrating the victim organization's session data. The vulnerability requires an authenticated user with the ability to create crawler tasks. The attacker must know or guess a valid cookiejar UUID belonging to another organization. The impact is unauthorized access to another organization's stored cookies and session data through the crawler infrastructure.

Technical Analysis

The AIL Framework's api_add_crawler_task API does not properly enforce authorization when attaching a cookiejar UUID to crawler tasks. The code only verifies cookiejar existence and, if the cookiejar's access level is 0, compares the owning user ID to the requesting user ID, but it does not validate organizational boundaries or the requesting user's role. For cookiejars with access level other than 0, no access check is performed. This allows an authenticated user with crawler task creation rights to use cookiejars from other organizations, leading to unauthorized access to stored cookies and session data.

Potential Impact

An attacker who is authenticated and able to create crawler tasks can access cookiejars from other organizations by referencing their UUIDs. This results in unauthorized access to session tokens and authentication credentials stored in those cookiejars, potentially leading to session data leakage or exfiltration across organizational boundaries.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict crawler task creation permissions to trusted users and monitor for suspicious use of cookiejar UUIDs. Validate organizational boundaries and user roles in any custom implementations or workarounds.
