In Edge Client version 7.2.x before 7.2.1.1, 7.1.9.x before 7.1.9.8, and 7.1.x-7.1.8.x before 7.1.8.5, an untrusted search path vulnerability in the BIG-IP APM Client Troubleshooting Utility (CTU) for Windows could allow an attacker to load a malicious DLL library from its current directory. User interaction is required to exploit this vulnerability in that the victim must run this utility on the Windows system. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
