Affected Product(s):
BIG-IP APM
Known Affected Versions:
17.1.2, 17.1.2.1, 17.1.2.2
Fixed In:
17.5.1.3, 17.1.3
Opened: Aug 20, 2025 Severity: 3-Major
Applications launched through BIG-IP virtual server start correctly, but the args parameter is dropped. Example: Command Prompt opens but does not execute ipconfig when launched with args=%2Fk%20ipconfig. When bypassing BIG-IP (direct VCS node access), the same URI executes the command successfully. Applications without args (e.g., Calculator) work as expected both with and without BIG-IP.
User cannot deep-link into specific app states or pass runtime arguments to published applications through BIG-IP. Breaks workflows relying on args, such as opening IBM Notes documents directly or running pre-defined commands in applications. Causes functional discrepancy between direct Horizon access and BIG-IP proxied access, leading to user frustration and support escalations.
VMware Horizon published applications behind BIG-IP APM. Launching applications via vmware-view:// URI with args parameter. Protocols tested: Blast, PCoIP. Issue occurs consistently when BIG-IP virtual server FQDN is used. Direct access to Horizon Connection Server (bypassing BIG-IP) does not exhibit the problem.
