Computer Associates Alert Notification Server Multiple Buffer Overflow Vulnerabilities

07.17.07

BACKGROUND

Computer Associates Alert Notification Server is used by several CA products, including eTrust Integrated Threat Management, to provide notifications to console users.

DESCRIPTION

Remote exploitation of multiple buffer overflow vulnerabilities in Computer Associates International Inc.'s (CA) Threat Manager allows attackers to execute arbitrary code with SYSTEM privileges.

When Computer Associates Threat Manager is installed, it also installs the Alert Notification Server (alert.exe) which registers an RPC interface with the GUID 3d742890-397c-11cf-9bf1-00805f88cb72. This interface contains stack-based buffer overflow vulnerabilities within the handling code for several RPC operation codes.

ANALYSIS

Exploitation allows an attacker to execute code with SYSTEM privileges on the targeted host.

The vulnerable code can be reached remotely using the SMB protocol. As such, valid credentials are required to exploit this vulnerability on Windows XP and newer systems. Windows 2000 based installations do not require credentials.
