Description

Activity Mod Plus contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to language/lang_english/lang_activity.php not properly sanitizing user input supplied to the 'phpbb_root_path' variable. This may allow an attacker to include a file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity
Exploit: Exploit Public, Exploit Unknown
Disclosure: OSVDB Verified
