The installer for BitDefender GravityZone relies on an encoded string in a filename to determine the URL for installation metadata, which allows remote attackers to execute arbitrary code by changing the filename while leaving the files digital signature unchanged.
Weakness
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
