Discussion

OTSCMS OTSCMS.PHP Multiple Remote File Include Vulnerabilities

OTSCMS is prone to multiple remote file-include vulnerabilities because it fails to properly sanitize user-supplied input.

A successful exploit of these issues allows an attacker to execute arbitrary server-side script code on an affected computer with the privileges of the webserver process. This may facilitate unauthorized access.

These versions are vulnerable:

- 1.0.0 through 1.0.3
- 1.3.0 through 1.4.1
- 2.0.0 through 2.1.3.

Other versions may also be affected.
