CVE-2026-42830 Details
Description
Untrusted search path in Azure Monitor Agent allows an authorized attacker to elevate privileges locally.
A vulnerability allowing privilege escalation has been identified in the Azure Monitor Agent Metrics Extension. This issue arises from an untrusted search path, which could enable an authorized attacker to elevate privileges locally. The vulnerability takes advantage of the OpenSSL configuration's auto-loading behavior, allowing extension modules to load automatically. If an attacker places a malicious DLL in a location referenced by the configuration, it could be implicitly loaded, potentially leading to arbitrary code execution with elevated privileges.
Users are advised to download the security update for the Azure Monitor Agent Metrics Extension. Instructions for downloading this update are available in the release notes on the Microsoft Learn website.
