CVE-2020-3350
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 in the endpoint software of Cisco AMP for Endpoints and Clam AntiVirus could allow an authenticated, local attacker to cause the running software to delete arbitrary files on the system. The vulnerability is due to a race condition that could occur when scanning malicious files. An attacker with local shell access could exploit this vulnerability by executing a script that could trigger the race condition. A successful exploit could allow the attacker to delete arbitrary files on the system that the attacker would not normally have privileges to delete, producing system instability or causing the endpoint software to stop working.

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.
-
Check Cisco AMP for Endpoints versionIdentify if Cisco AMP for Endpoints is installed and retrieve its version number using system package management tools or the AMP-specific diagnostic commandAffected if The installed version is below 1.12.4
-
Check ClamAV versionRun 'clamd --version' or check the installed clamd package version using the system package managerAffected if The installed ClamAV version is below 0.102.4
-
Determine if file scanning service is activeCheck if the ClamAV daemon (clamd) or AMP connector service is running and configured to scan files on accessAffected if The scanning service is enabled and actively processing files, which is required to trigger the race condition
-
Verify local shell access exposureAssess whether untrusted local users have shell access to the system, as the vulnerability requires authenticated local attacker accessAffected if Untrusted local users have shell access to the affected system
You are affected if either Cisco AMP for Endpoints is installed below version 1.12.4 or ClamAV is installed below version 0.102.4, and the file scanning service is active with untrusted local users having shell access.

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 data0.102.41.12.4
Apply vendor security updates/patches from Cisco for AMP for Endpoints and ensure ClamAV is updated to the latest version to remediate the race condition.
