Account compromise via accepted weak passwords
Published Nov 18, 2025 · Updated Nov 19, 2025
Weak password enforcement in LibreNMS before 25.11.0 allows remote attackers to compromise accounts through password guessing. The user-creation password validator accepts common compromised values such as 12345678 without applying a strong-password or breached-password rejection rule. An administrator must first create an account with a predictable password, after which remote attackers can obtain that account's access by brute force or credential stuffing.
