A vulnerability was determined in FeehiCMS up to 2.1.1. Impacted is an unknown function of the file frontend/web/timthumb.php of the component TimThumb. Executing manipulation of the argument src can lead to server-side request forgery. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

FeehiCMS version 2.1.1 fails to enforce server-side immutability for parameters that are presented to clients as "read-only." An authenticated attacker can intercept and modify the parameter in transit and the backend accepts the changes. This can lead to unintended username changes.

FeehiCMS version 2.1.1 has a Remote Code Execution via Unrestricted File Upload in Ad Management. FeehiCMS version 2.1.1 allows authenticated remote attackers to upload files that the server later executes (or stores in an executable location) without sufficient validation, sanitization, or execution restrictions. An authenticated remote attacker can upload a crafted PHP file and cause the application or web server to execute it, resulting in remote code execution (RCE).
