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
