Technical impact
The vulnerability is a missing authorization check in FaveoSuite Faveo Helpdesk's UnAuthController functions, which allows an attacker to manipulate the id and status arguments. An attacker can remotely change ticket status, close, open, or resolve tickets without having the required permissions. This leads to integrity violations on support tickets and can compromise the business logic of the helpdesk system.
Affected Systems
FaveoSuite Faveo Helpdesk versions up to and including 2.0.3 are affected. Any installation running 2.0.3 or earlier and exposing the UnAuthController endpoints is vulnerable.
Risk and Exploitability
The CVSS score of 6.9 indicates moderate severity. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. The attacker can launch the exploit remotely by sending crafted HTTP requests to the UnAuthController endpoints. Though the exploit does not require privileged credentials, it bypasses authorization checks, allowing unauthorized users to alter ticket data and potentially disrupt support operations.
