How CVE-2025-32986 Works
CVE-2025-32986 is an authentication bypass flaw in NETSCOUT nGeniusONE versions before 6.4.0 b2350. The vulnerability allows unauthenticated attackers to access sensitive files via a misconfigured endpoint. The system fails to enforce proper authentication checks, enabling direct retrieval of confidential data such as configuration files, logs, or credentials. Attackers exploit this by crafting HTTP requests to the exposed endpoint, bypassing security controls. The impact includes data leaks, privilege escalation, and potential system compromise.
