What is CVE-2016-1542?

The RPC API in the RSCD agent of BMC BladeLogic Server Automation allows remote attackers to bypass authorization mechanisms and enumerate user accounts. By sending specifically crafted action packets to the xmlrpc interface following an authorization failure, unauthorized parties can gain insights into the existence of users in the system. This vulnerability exposes key user information, potentially facilitating further attacks or unauthorized access.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
