## Affected

- F5 BIG-IP APM: from 15.1.x, fixed in 15.1.4; from 16.1.x, fixed in 16.1.1

## Description

In BIG-IP Versions 16.1.x before 16.1.1 and 15.1.x before 15.1.4, when running in Appliance mode, an authenticated attacker may be able to bypass Appliance mode restrictions due to a directory traversal vulnerability in an undisclosed page within iApps. A successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
