CVE-2025-2311

Low-privilege authentication bypass and credential exposure

Published Mar 20, 2025 · Updated Jun 6, 2026

Authentication flaws in SecHard Information Technologies' SecHard before 3.3.0.20220411 allow remote authenticated users to bypass controls. The published record attributes the issue to privileged API misuse, cleartext transmission, and insufficient credential protection, but identifies no specific endpoint or incorrect operation. Adjacent-network access and low privileges are required; successful abuse permits interface manipulation, authentication abuse, and API-event monitoring.
