I. BACKGROUND
Computer Associates Alert Notification Server is used by several CA products,
including eTrust Integrated Threat Management, to provide notifications to
console users.
II. 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.
III. 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.
IV. DETECTION
iDefense confirmed that the Alert Notification Server included with Computer
Associates International Inc.'s eTrust Integrated Threat Management r8 for
Windows is vulnerable.
V. WORKAROUND
iDefense is currently unaware of any workarounds for this issue.
VI. VENDOR RESPONSE
