Stack Buffer Overflow in RealPlayer SMIL Parser

IdentifiersCVE-2005-0455CWE-121

A stack-based buffer overflow exists in RealNetworks RealPlayer (versions 10.5, 10, 8, RealOne Player V2 and V1) within the CSmil1Parser::testAttributeFailed function in smlparse.cpp. The vulnerability is triggered when a specially crafted .SMIL file containing an overly large system-screen-size value is parsed, leading to a buffer overflow condition.

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 user running RealPlayer, potentially leading to full system compromise.

Mitigation

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

As an interim measure, avoid opening untrusted .SMIL files or files from unknown sources. Employ host-based intrusion prevention systems and restrict execution of RealPlayer where possible until patched.

Remediation

Patch, then assume compromise.

Upgrade to a patched version of RealPlayer that addresses this buffer overflow vulnerability. RealNetworks has released updates that correct the issue in affected versions.

realplayer_smil.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in RealNetworks RealPlayer versions 10 (build 6.0.12.883) and 8 (build 6.0.9.584) on Windows 2000 and Windows XP. The exploit works by serving a malicious SMIL file via an HTTP server (implemented by the module) to a victim. When the victim opens the crafted SMIL file in a vulnerable RealPlayer, a buffer overflow is triggered, allowing the attacker to execute arbitrary code. The module allows the attacker to specify a payload, which is embedded in the SMIL file and delivered to the victim. The only file in the repository is a Ruby script structured as a standard Metasploit module, making use of the Metasploit framework's HTTP server and payload generation capabilities. The main attack vector is browser-based, requiring user interaction (opening a malicious URL). The only fingerprintable endpoint is the HTTP path serving the .smil file.
