An issue was discovered in Titan SpamTitan 7.07. Improper sanitization of the parameter fname, used on the page certs-x.php, would allow an attacker to retrieve the contents of arbitrary files. The user has to be authenticated before interacting with this page.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
