CVE-2024-7193
📋 TL;DR
This vulnerability in Mp3tag allows attackers to execute arbitrary code by placing a malicious DLL in a location where the application searches for dependencies. It affects users running Mp3tag versions up to 3.26d on Windows systems. Attackers need local access to the target system to exploit this vulnerability.
💻 Affected Systems
- Mp3tag
📦 What is this software?
Mp3tag by Mp3tag
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the Mp3tag user, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local privilege escalation or execution of malicious code within the user context, allowing attackers to steal sensitive files, install keyloggers, or pivot to other systems.
If Mitigated
Limited impact if users run with minimal privileges and have proper endpoint protection that detects DLL hijacking attempts.
🎯 Exploit Status
Exploit has been publicly disclosed and requires local access to place malicious DLL in search path. Attack complexity is low once attacker has local access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.26e
Vendor Advisory: https://community.mp3tag.de/t/mp3tag-development-build-status/455/1

🔧 Temporary Workarounds
Restrict DLL search path
windowsUse Windows policies to restrict where applications can load DLLs from
Set SafeDllSearchMode registry key to 1: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SafeDllSearchMode
Remove vulnerable DLL
windowsRemove or rename the vulnerable tak_deco_lib.dll file
del "C:\Program Files\Mp3tag\tak_deco_lib.dll"
ren "C:\Program Files\Mp3tag\tak_deco_lib.dll" tak_deco_lib.dll.bak
🧯 If You Can't Patch
- Run Mp3tag with minimal user privileges to limit potential damage from exploitation
- Use application whitelisting to prevent execution of unauthorized DLLs
