Technical description

Insecure Permission vulnerability in Schlix Web Inc SCHLIX CMS 2.2.7-2 allows attacker to upload arbitrary files and execute arbitrary code via the tristao parameter. NOTE: this is disputed by the vendor because an admin is intentionally allowed to upload new executable PHP code, such as a theme that was obtained from a trusted source or was developed for their own website. Only an admin can upload such code, not someone else in an "attacker" role.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
