描述

CVE-2022-1388 is an authentication bypass vulnerability in the REST      component of BIG-IP’s iControl API that was assigned a CVSSv3      score of 9.8. The iControl REST API is used for the management and      configuration of BIG-IP devices. CVE-2022-1388 could be exploited      by an unauthenticated attacker with network access to the management      port or self IP addresses of devices that use BIG-IP. Exploitation would      allow the attacker to execute arbitrary system commands, create and      delete files and disable services.

介绍

# Nuclei Template Exploit F5 BIG-IP iControl REST Auth Bypass RCE | Command Parameter
CVE-2022-1388 is an authentication bypass vulnerability in the REST 
component of BIG-IP’s iControl API that was assigned a CVSSv3 
score of 9.8. The iControl REST API is used for the management and 
configuration of BIG-IP devices. CVE-2022-1388 could be exploited 
by an unauthenticated attacker with network access to the management 
port or self IP addresses of devices that use BIG-IP. Exploitation would 
allow the attacker to execute arbitrary system commands, create and 
delete files and disable services.

## This template use token-spray / nuclei's CLI variable 
This nuclei-template accepts shell parameter for exploitation.
We wanted to test tokens obtained from another workflow or a manual search, so we used nuclei's CLI variable feature to dynamically feed a single token value or list of tokens into these templates at run time

> `-V, -var value              custom vars in var=value format`
