Stack-based Buffer Overflow in BlazeVideo HDTV Player Pro .plf Playlist Parsing

IdentifiersCVE-2012-10031CWE-121· Stack-based Buffer Overflow

CVE-2012-10031 affects BlazeVideo HDTV Player Pro v6.6.0.3. The vulnerability is a stack-based buffer overflow in the handling of user-controlled data embedded in .plf playlist files. During parsing of a crafted .plf file, the MediaPlayerCtrl.dll component calls PathFindFileNameA() to obtain a filename from a URL-like string, then copies the returned value into a fixed-size stack buffer using an inline strcpy operation without bounds checking. An overlong filename value can therefore overwrite stack memory, causing a crash and potentially enabling arbitrary code execution in the security context of the current user.

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 can corrupt stack memory and crash the application, resulting in denial of service. Because the overflow is stack-based and occurs through an unchecked strcpy into a fixed-size buffer, a sufficiently controlled payload may allow arbitrary code execution under the privileges of the user running BlazeVideo HDTV Player Pro.

Mitigation

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

Do not open untrusted or externally supplied .plf playlist files with BlazeVideo HDTV Player Pro v6.6.0.3. Restrict delivery of playlist files from email, web downloads, and shared locations where possible. Apply application control or sandboxing to reduce impact, and run the software with the least privileges possible to limit post-exploitation effects.

Remediation

Patch, then assume compromise.

Upgrade to a vendor-fixed version if one is available. The vulnerable code path should be corrected by replacing the unbounded strcpy with a bounds-checked copy routine and by validating the length of the filename returned from PathFindFileNameA() before copying it into a stack buffer. If no patch is available, discontinue use of the affected version 6.6.0.3.

blazedvd_hdtv_bof.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module targeting a stack-based buffer overflow vulnerability in BlazeVideo HDTV Player Pro v6.6.0.3 (CVE-2012-10031). The exploit abuses improper filename handling in the MediaPlayerCtrl.dll component, where a long filename embedded in a specially crafted .plf file triggers a buffer overflow via an unsafe strcpy operation. The module generates a malicious .plf file (default name: msf.plf) containing a payload that overwrites the SEH (Structured Exception Handler) and executes arbitrary code when opened by the vulnerable application. The exploit is operational, allowing the attacker to select and encode a payload using Metasploit's framework. The attack vector is local, requiring user interaction to open the malicious file. The only fingerprintable endpoint is the generated .plf file. The code is written in Ruby and follows the standard Metasploit module structure.
