CVE-2024-10093
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability, which was classified as critical, was found in VSO ConvertXtoDvd 7.0.0.83. Affected is an unknown function in the library avcodec.dll of the file ConvertXtoDvd.exe. The manipulation leads to uncontrolled search path. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceVSO ConvertXtoDvd 7.0.0.83 contains an uncontrolled search path vulnerability in how the application loads the avcodec.dll library. The DLL is loaded without a fully qualified path, allowing a local attacker to place a malicious DLL in a directory that gets searched before the legitimate DLL location (DLL search order hijacking), achieving arbitrary code execution with the privileges of the logged-on user.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify ConvertXtoDVD versionCheck if the installed version is exactly 7.0.0.83 by looking at the program's version information in the application directory or through Programs and FeaturesAffected if Version is 7.0.0.83
-
Inspect application directory for unauthorized DLLsExamine the ConvertXtoDVD installation folder for any unexpected DLL files, particularly avcodec.dll if it does not match the original legitimate DLLAffected if A DLL file exists in the application directory that was not placed there by the legitimate installer
-
Check application execution directoryDetermine the directory from which ConvertXtoDVD is being launched; check if it is run from directories like Downloads, Temp, or network shares where untrusted users could write filesAffected if The application is launched from a directory writable by other users or from an untrusted location
-
Verify avcodec.dll loading behaviorUse Process Monitor or similar tool to observe which avcodec.dll the application attempts to load and from which path it is loaded at runtimeAffected if The application loads avcodec.dll from a directory other than the legitimate installation path or the Windows system directories
A user is affected if they have version 7.0.0.82 or 7.0.0.83 installed and the application loads avcodec.dll from a location that could be influenced by an attacker, or if unauthorized DLLs exist in the application directory.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement secure DLL loading by using explicit full paths for all LoadLibrary calls or enabling Safe DLL Search Mode; the vendor has not released a patch so users should avoid running the application from untrusted directories and monitor for suspicious DLLs in the application directory.
