# Dell OpenManage Enterprise: signature check flaw allows code execution by admins

Dell OpenManage Enterprise versions before 4.8.0 do not properly verify a cryptographic signature. A high-privileged attacker on an adjacent network can potentially exploit this to execute code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed OpenManage Enterprise version in the web console or on the appliance; unknown whether a specific command is given by the sources.
- Confirm whether the version is below `4.8.0`.

## Fix

- Dell OpenManage Enterprise: move to `4.8.0` or later.

## Timeline

## From the sources

Dell OpenManage Enterprise, versions prior to 4.8.0, contains an Improper Verification of Cryptographic Signature vulnerability. A high privileged attacker with adjacent network access could potentially exploit this vulnerability, leading to Code execution.
