HTTP: vBulletin DecodeArguments PHP Object Injection Attempt
This signature detects attempts to exploit a known PHP object injection vulnerability in vBulletin. In a successful code injection attack, the behavior of the target host is entirely dependent on the intended function of the injected code and executes within the security context of the currently logged in user. If the attack is unsuccessful, the vulnerable application can terminate abnormally.
