CVE-2022-48174
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 · uneditedThere is a stack overflow vulnerability in ash.c:6030 in busybox before 1.35. In the environment of Internet of Vehicles, this vulnerability can be executed from command to arbitrary code execution.
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 stack buffer overflow vulnerability exists in ash.c:6030 in BusyBox versions prior to 1.35. The flaw allows attackers to execute arbitrary code via command injection through the ash shell, posing significant risk in Internet of Vehicles deployments where BusyBox is widely used in embedded systems.

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 installed BusyBox versionRun `busybox --version` or `busybox -v` to display the version stringAffected if The displayed version is 1.35 or lower, or 1.36.1 or lower (check against both ranges since the exact boundary is unclear)
-
Verify ash shell is in useCheck the current shell by running `echo $SHELL` or `ps -p $$` to identify the active shell processAffected if The shell is identified as ash, sh linked to ash, or BusyBox ash
-
Confirm ash module is presentRun `busybox --list` or `ls -la /bin/sh` to verify ash is compiled into the BusyBox binaryAffected if ash is listed as an available applet or /bin/sh points to busybox
-
Check ash.c source file version if accessibleIf the BusyBox source is available, inspect ash.c and look near line 6030 for the vulnerable code pattern involving stack buffer operationsAffected if The source at ash.c:6030 contains the unchecked buffer operation present in vulnerable versions
You are affected if BusyBox version is at or below the vulnerable threshold (verify exact range from official sources) AND the ash shell module is enabled and in use.

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 · scopedUpgrade BusyBox to version 1.35 or later to remediate this critical vulnerability. In IoV environments where immediate patching is not feasible, implement input validation and restrict shell command access to prevent exploitation.
BusyBox 1.35 or later (Debian 11 default repository version)
- 1. Identify the current BusyBox version installed on the system using: `busybox --version`
- 2. For Debian 11 (Bullseye), update the package repository: `sudo apt-get update`
- 3. Upgrade BusyBox to the latest available version in Debian 11: `sudo apt-get install --only-upgrade busybox`
- 4. Verify the updated version: `busybox --version`
- 5. Restart any critical services that depend on the BusyBox utilities if necessary
