Schlix Web · Schlix Cms · CVE-2022-45544
**Name of the Vulnerable Software and Affected Versions**
Schlix Web Inc SCHLIX CMS version 2.2.7-2
**Description**
The issue allows an attacker to upload arbitrary files and execute arbitrary code via the `tristao` parameter. However, it is noted that this functionality is intentionally allowed for admins to upload new executable PHP code from trusted sources. The vulnerability is disputed by the vendor as it requires admin privileges to upload such code.
**Recommendations**
For version 2.2.7-2, consider restricting access to the `tristao` parameter to prevent unauthorized file uploads and code execution. As a temporary workaround, restrict the ability to upload new executable PHP code to only trusted sources and ensure that all admins are aware of the potential risks associated with this functionality.
