Format String Vulnerability in EMC NetWorker nsrd RPC Service

IdentifiersCVE-2012-2288CWE-134· Use of Externally-Controlled…

A format string vulnerability exists in the nsrd RPC service of EMC NetWorker versions 7.6.3, 7.6.4 before 7.6.4.1, and 8.0 before 8.0.0.1. The vulnerability allows remote attackers to execute arbitrary code by sending crafted messages containing format string specifiers to the service. The flaw is due to improper handling of user-supplied input in format string functions within the nsrd RPC service.

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 with the privileges of the nsrd service, potentially leading to full system compromise. This can be leveraged for further lateral movement or persistence within the affected environment.

Mitigation

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

If immediate patching is not possible, restrict network access to the nsrd RPC service to trusted hosts only, and monitor for suspicious activity targeting the service. Consider network segmentation and firewall rules to limit exposure.

Remediation

Patch, then assume compromise.

Upgrade EMC NetWorker to version 7.6.4.1 or 8.0.0.1 or later, where the vulnerability has been addressed. Apply all relevant vendor patches as soon as possible.

networker_format_string.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (modules/exploits/windows/emc/networker_format_string.rb) that exploits a format string vulnerability (CVE-2012-2288) in EMC Networker 7.6 SP3 for Windows. The exploit targets the lg_sprintf function in liblocal.dll by sending a specially crafted SunRPC call to program number 0x5F3DD, version 2, procedure 6. The module supports multiple Windows targets (XP SP3, 2003 SP2) and includes logic to bypass DEP using a custom ROP chain when necessary. The payload is customizable and encoded to avoid bad characters, allowing for arbitrary code execution on the target system. The exploit is operational and requires network access to the vulnerable SunRPC service. The repository is part of the Metasploit framework and is structured as a standard Metasploit exploit module.
