Critical

VectorAV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions F5 BIG-IP versions 11.6.1 through 11.6.5.2 F5 BIG-IP versions 12.1.0 through 12.1.5.2 F5 BIG-IP versions 13.1.0 through 13.1.3.4 F5 BIG-IP versions 14.1.0 through 14.1.2.7 F5 BIG-IP versions 15.1.0 through 15.1.0.5 F5 BIG-IP versions 16.0.0 through 16.0.0.1
Description The issue concerns undisclosed endpoints in iControl REST, which allow for a reflected XSS attack. This could lead to a complete compromise of the BIG-IP system if the victim user is granted the admin role.
Recommendations For F5 BIG-IP versions 11.6.1 through 11.6.5.2, update to a version outside of this range to mitigate the risk. For F5 BIG-IP versions 12.1.0 through 12.1.5.2, update to a version outside of this range to mitigate the risk. For F5 BIG-IP versions 13.1.0 through 13.1.3.4, update to a version outside of this range to mitigate the risk. For F5 BIG-IP versions 14.1.0 through 14.1.2.7, update to a version outside of this range to mitigate the risk. For F5 BIG-IP versions 15.1.0 through 15.1.0.5, update to a version outside of this range to mitigate the risk. For F5 BIG-IP versions 16.0.0 through 16.0.0.1, update to a version outside of this range to mitigate the risk. As a temporary workaround, consider restricting access to the undisclosed endpoints in iControl REST to minimize the risk of exploitation.
