#The AMS2 (Alert Management Systems 2) component of multiple Symantec products is prone to a remote #command-execution vulnerability because the software fails to adequately sanitize user-supplied #input.

#Successfully exploiting this issue will allow an attacker to execute arbitrary commands with #SYSTEM-level privileges, completely compromising affected computers. Failed exploit attempts will #result in a denial-of-service condition.
