CVE-2026-41858 - BOSH-Ecosystem windows-utilities-release Weak Randomness Leading to Administrator Password Recovery

CVE ID :CVE-2026-41858
Published : June 4, 2026, 2:10 a.m. | 52 minutes ago
Description :Weak Randomness / Insecure Cryptographic Primitive (CWE-338) in Get-RandomPassword in BOSH-Ecosystem / windows-utilities-release allows a network attacker to estimate VM boot time and reconstruct a small candidate list to recover the Administrator password. The randomize_password job exists solely to lock the local Administrator account behind an unguessable password as a hardening control. Because the password is derived from a predictable, clock-seeded PRNG, a network attacker who can estimate VM boot time can reconstruct a small candidate list and recover the Administrator password, defeating the hardening control. Affected versions: - windows-utilities-release: all versions prior to v0.23.0 (inclusive); fixed in v0.23.0 or later
Severity: 6.5 | MEDIUM
