Credential decrypter for ManageEngine OpManager version 11.x and 12.2 Tested on Free and Essential version

Abusing some SQL Injection on OpManager, is it possible to dump the table that contains managed devices' username/password and ip.

OpManager encrypts password before to store them in the database. Of course OpManager need passwords in plaintext to login on devices so the alghoritm couldn't be one-way. The encryption algorithm doesn't use a per-site key therefore reversing^Hguessing the algorithm leads to decryption of credentials on every (tested) installation.

Notified to the vendor the 7th of April 2015, no fix nor workaround yet.

Assigned CVE-2015-9107

Usage:

$ javac DecryptOpManager

$ java -cp . DecryptOpManager [encrypt|decrypt] string
