Title: FCheck Local Command Execution Vulnerability
Severity: MODERATE
Description:
Fcheck is a perl-based file integrity checker which makes use of external programs (such as MD5) to run specific tests on the structure and contents of datafiles.
Vulnerable versions of FCheck use an insecurely-structured call to open(), argumented by the name of an input file.
Shell metacharacters embedded in a filename can cause commands hidden in the text of that filename to be improperly passed to a command interpreter for execution.
As a result, the commands within the attacker's hostile filename will be run with the privilege level of the fcheck uid, potentially root.
