Bug ID 601924: Selenium detection by ports scanning doesn't work even if the ports are opened

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP ASM(all modules)

Known Affected Versions:
12.1.0, 12.1.1

Fixed In:
13.0.0, 12.1.2

Opened: Jun 28, 2016

Severity: 3-Major


When selenium server package is running on an end point and a traffic being sent from there, proactive bot defense mechanism doesn't see selenium server opened ports.


Low impact as the selenium detection by ports scan has a low score and doesn't mitigate a client, unless it has another suspicious client properties (for example tor browser)


This occurs when ASM is provisioned with proactive bot defense enabled.



Fix Information

Ports scanning has fixed - wider range of ports are scanned.
