Stack Buffer Overflow in Novell iPrint Client ienipp.ocx

IdentifiersCVE-2009-1568CWE-121

A stack-based buffer overflow exists in the ienipp.ocx ActiveX control in Novell iPrint Client version 5.30 and possibly earlier versions prior to 5.32. The vulnerability is triggered by supplying an overly long value to the target-frame parameter, which can overwrite the stack and allow for arbitrary code execution.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows remote attackers to execute arbitrary code in the context of the user running the vulnerable ActiveX control, potentially leading to full system compromise.

Mitigation

If you can’t patch tonight, do this now.

Disable the affected ActiveX control in Internet Explorer, restrict access to trusted sites, and use browser security settings to prevent untrusted code execution until the client is updated.

Remediation

Patch, then assume compromise.

Upgrade Novell iPrint Client to version 5.32 or later, which addresses this buffer overflow vulnerability.

novelliprint_target_frame.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the Novell iPrint Client 5.30 ActiveX control (ienipp.ocx) for Windows (CVE-2009-1568). The exploit is delivered via a malicious HTML page served by the Metasploit HTTP server. When a victim visits the page with a vulnerable version of the iPrint Client installed, an overly long 'target-frame' parameter is passed to the ActiveX control, triggering a buffer overflow and allowing arbitrary code execution. The module supports customizable payloads (up to 1456 bytes, avoiding null bytes) and leverages Metasploit's payload generation and handling capabilities. The exploit is operational and can be used to gain code execution on affected systems. The main file is written in Ruby and follows the standard Metasploit module structure, with the attack vector being browser-based exploitation of a vulnerable ActiveX control. Key fingerprintable endpoints include the vulnerable OCX file, the HTTP server endpoint, and the CLSID of the ActiveX control.
