CVE-2021-25450
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 · uneditedPath traversal vulnerability in FactoryAirCommnadManger prior to SMR Sep-2021 Release 1 allows attackers to write file as system uid via remote socket.
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 confidenceA path traversal vulnerability in FactoryAirCommandManager prior to SMR Sep-2021 Release 1 allows remote attackers to write arbitrary files to the filesystem with system (root) privileges via remote socket communication. The vulnerability stems from insufficient input validation of file paths in the FactoryAirCommandManger component, enabling authenticated attackers to escape the intended directory and write files outside the expected path.

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 Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The device runs Android 8.1, 9.0, 10.0, or 11.0
-
Confirm Samsung firmwareCheck if the device is Samsung brand by verifying 'getprop ro.product.brand' returns 'samsung'Affected if The device is not Samsung firmware (FactoryAirCommandManager is Samsung-specific)
-
Verify SMR patch levelRun 'getprop ro.build.version.sem' or check Settings > About Phone > Software info > Security patch levelAffected if The security patch level is earlier than September 2021 (SMR Sep-2021 Release 1)
-
Check for FactoryAirCommandManager componentRun 'pm list packages | grep -i aircommand' or check for the presence of /system/priv-app/FactoryAirCommandManager/ via ADB shellAffected if The FactoryAirCommandManager component is installed on the device
A device is affected if it is a Samsung Android device running version 8.1, 9.0, 10.0, or 11.0 with the FactoryAirCommandManager component present and a security patch level before September 2021.

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.
dbcve · scopedApply the SMR Sep-2021 Release 1 patch or later to address the path traversal vulnerability. Additionally, implement strict input validation and sandboxing for the FactoryAirCommandManger component to restrict file write operations to authorized directories.
SMR Sep-2021 Release 1 or later
- On the Samsung Android device, navigate to Settings
- Tap on 'Software update' or 'About phone' > 'Software update'
- Tap 'Download and install' or 'Check for updates'
- Apply the September 2021 Samsung Security Update (SMR Sep-2021 Release 1)
- Restart the device after the update completes
