BIG-IP ASM(all modules)

Opened: Jul 20, 2019
Severity: 4-Minor

Symptoms

When Bot Defense is used on the backend server that overrides request cookies, requests to non-HTML resources may fail, or may receive the whitepage JavaScript challenge. An example is when a back-end server responds with a Set-Cookie header containing empty values for each cookie request cookie it did not recognize.

Impact

Some URLs fail to load following the JavaScript challenge.

Conditions

-- Bot Defense is enabled. -- Backend server is overriding the TS Bot Defense cookies.

Workaround

Use an iRule to strip the TSPD_101 cookie from the request before forwarding it to the backend: when HTTP_REQUEST_RELEASE { HTTP::cookie remove "TSPD_101" }

Fix Information

None
