SEH-based stack buffer overflow in Xion Audio Player .m3u parsing

IdentifiersCVE-2010-20042CWE-121· Stack-based Buffer Overflow

CVE-2010-20042 affects Xion Audio Player versions prior to 1.0.126. The vulnerability is a Unicode-based stack buffer overflow triggered when the application opens a specially crafted .m3u playlist file containing an overly long string. Processing of the malicious playlist causes a stack-based overwrite that corrupts the Structured Exception Handler (SEH) chain, enabling control-flow hijacking. Successful exploitation can result in arbitrary code execution in the context of the user running Xion Audio Player.

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 arbitrary code execution on the target system in the security context of the user who opens the malicious playlist in Xion Audio Player. Because the overflow overwrites the SEH chain, an attacker can redirect execution flow to attacker-controlled payloads. This can lead to full compromise of the affected user session, including malware installation, data access, persistence, or use of the host as a pivot, subject to the privileges of the user account.

Mitigation

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

Do not open .m3u playlist files from untrusted or unauthenticated sources. Apply least-privilege principles so the player does not run with administrative rights. Use endpoint protections that can detect malformed media playlist exploit attempts, and consider application allowlisting or sandboxing for media players to reduce post-exploitation impact. Restrict delivery vectors such as email attachments and downloads from untrusted sites where practical.

Remediation

Patch, then assume compromise.

Upgrade Xion Audio Player to version 1.0.126 or later, as versions prior to 1.0.126 are affected. If upgrading is not possible, discontinue use of the vulnerable version and avoid opening untrusted .m3u playlist files.

xion_m3u_sehbof.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in Xion Audio Player versions prior to 1.0.126 (CVE-2010-20042). The exploit works by generating a specially crafted M3U playlist file ('m_101_xion.m3u') that, when opened by the vulnerable application, triggers a Unicode stack buffer overflow via an overly long string, overwriting the Structured Exception Handler (SEH) and allowing arbitrary code execution. The module uses Metasploit's payload system, allowing the attacker to select from a variety of payloads (such as reverse shells or Meterpreter sessions), which are encoded to bypass bad characters. The exploit is operational and requires the victim to manually open the malicious file. The only fingerprintable endpoints are the generated M3U file and the default output path. The code is written in Ruby and is structured as a standard Metasploit exploit module, making it easy to use within the Metasploit framework.
