Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Forkcms/forkcms, 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

Multiple cross-site request forgery (CSRF) vulnerabilities in the Admin Console in Fork before 5.8.3 allows remote attackers to perform unauthorized actions as administrator to (1) approve the mass of the user's comments, (2) restoring a deleted user, (3) installing or running modules, (4) resetting the analytics, (5) pinging the mailmotor api, (6) uploading things to the media library, (7) exporting locale.
