**Name of the Vulnerable Software and Affected Versions**
OTCMS version 6.0.1
**Description**
A critical vulnerability was found in OTCMS, related to the absence of restrictions on file uploads. This issue affects an unknown functionality of the file sysCheckFile.php, where the `mudi` parameter is set to `sql`. The manipulation leads to unrestricted upload, allowing a remote attacker to upload arbitrary files and potentially execute arbitrary code. The exploit has been disclosed to the public.
**Recommendations**
For OTCMS version 6.0.1, consider disabling the sysCheckFile.php file or restricting access to it until a patch is available. As a temporary workaround, avoid using the `mudi` parameter in the sysCheckFile.php file to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
