Name of the Vulnerable Software and Affected Versions zzzphp cms version 1.5.8

Description An issue was discovered that allows remote attackers to delete arbitrary files. This is possible due to the del file function in the /admin/save.php endpoint, which can be exploited by using a mixed-case extension and an extra '.' character. For example, while "php" is blocked, a path like "F:/1.phP" can succeed.

Recommendations For zzzphp cms version 1.5.8, consider restricting access to the del file function in the /admin/save.php endpoint until a patch is available. As a temporary workaround, avoid using mixed-case extensions in file paths to minimize the risk of exploitation.
