CVE-2024-9495
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 · uneditedDLL hijacking vulnerabilities, caused by an uncontrolled search path in the CP210x VCP Windows installer can lead to privilege escalation and arbitrary code execution when running the impacted installer.
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 · moderate confidenceDLL hijacking vulnerability in the CP210x VCP Windows installer caused by an uncontrolled search path allows privilege escalation and arbitrary code execution when a user runs the maliciously crafted or compromised installer.

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.
-
Identify if CP210x VCP software is installedCheck for the presence of Silicon Labs CP210x VCP driver files in common installation directories such as C:\Program Files\Silicon Labs\ or C:\Program Files (x86)\Silicon Labs\, and look for files named CP210xVCP.exe or similar installer remnants in Add/Remove ProgramsAffected if CP210x VCP software from Silicon Labs is present on the system
-
Locate the CP210x VCP installer executableSearch the filesystem for files matching *CP210x*VCP*installer*.exe, *CP210x*.exe, or SiLabs*.exe in user-accessible directories such as Downloads, Temp, or user profile folders using commands like Get-ChildItem -Recurse or dir /sAffected if A CP210x VCP installer executable exists in a directory with weak permissions
-
Check for unauthorized DLLs in installer search pathsAfter locating the installer, inspect directories in the Windows PATH environment variable and the installer's execution directory for unexpected DLL files (such as version.dll, setupapi.dll, or other common targets) that may have been plantedAffected if Unexpected DLL files are found in directories the installer searches or in its execution path
-
Review system for privilege escalation indicatorsExamine Windows Event Logs (Security and Application logs) around the time the CP210x installer was executed for events indicating new user accounts, privilege changes, or suspicious process execution at elevated privilegesAffected if Event log entries show creation of unexpected accounts or privilege escalations coinciding with installer execution
-
Scan for known malicious DLLs associated with this vulnerabilityUse antivirus or endpoint detection software to scan directories where the installer was run for known malicious DLLs that could be loaded via search path hijacking, or manually compare any found DLLs against known malware signaturesAffected if Antivirus or manual inspection reveals malicious DLLs in installer-related directories
A system is likely affected if the CP210x VCP installer from Silicon Labs has been executed and suspicious DLLs or privilege escalation artifacts are found in associated directories or logs.
