Determine the running software version of a remote F5 BIG-IP management interface. Developed with ❤️ by the Bishop Fox Cosmos team.
CVE-2022-1388, a critical vulnerability in the F5 BIG-IP management interface, allows an attacker to bypass authentication and remotely execute arbitrary system commands. Bishop Fox developed a BIG-IP scanner that you can use to determine:
- Which software version is running on a remote F5 BIG-IP management interface
- Whether a specific appliance is affected by any known vulnerabilities, including CVE-2022-1388—all without sending any malicious traffic to the server (i.e., risking being blocked by a WAF)
See full write-up for this tool at the Bishop Fox blog, including a complete walkthrough of the methodology behind building the version table.
git clone https://github.com/bishopfox/bigip-scanner.git && cd bigip-scanner
python3 -m venv venv
source venv/bin/activate
python3 -m pip install -U pip
python3 -m pip install -r requirements.txt
$ python3 bigip-scanner.py -h
usage: bigip-scanner.py [-h] -t TARGET [-v VERSION_TABLE] [-a] [-d]
Determine the running software version of a remote F5 BIG-IP management interface.

optional arguments:
-h, --help show this help message and exit
-t TARGET https://example.com
-v VERSION_TABLE version-table.csv
-a request all resources; don't stop after an exact match
-d debug mode
In the following example, https://example.com/tmui/tmui/login/images/logo_f5.png has an HTTP response header that indicates that it's running BIG-IP version 16.1.2-0.0.18 which, according to F5's security advisory, is in the vulnerable range for CVE-2022-1388.
$ python3 bigip-scanner.py -t https://example.com | jq
