CVE-2015-3326

Estado: ModificadaMedia (5)—

Trend Micro ScanMail for Microsoft Exchange (SMEX) 10.2 before Hot Fix Build 3318 and 11.0 before Hot Fix Build 4180 creates session IDs for the web console using a random number generator with predictable values, which makes it easier for remote attackers to bypass authentication via a brute force attack.
