Technical details
An untrusted search path vulnerability (CWE-426) exists in the Microsoft Azure Monitor Agent. The flaw occurs when the application attempts to load a resource or library without specifying a fully qualified path, potentially allowing a local attacker to place a malicious file in a directory searched by the application. To exploit this, an attacker must have local access with low-level privileges. Successful exploitation allows the attacker to execute code with elevated privileges, potentially impacting the integrity of the host system. Microsoft has released security updates to address this issue.
