Bind Shell Backdoor Detection

critical Nessus Plugin ID 51988
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote host may have been compromised.


A shell is listening on the remote port without any authentication being required. An attacker may use it by connecting to the remote port and sending commands directly.


Verify if the remote host has been compromised, and reinstall the system if necessary.
