Executive Summary

CVE-2026-41858 is a vulnerability in the windows-utilities-release component of the BOSH-Ecosystem. It involves weak randomness due to an insecure cryptographic primitive in the Get-RandomPassword function. Specifically, the password for the local Administrator account is generated using a predictable, clock-seeded pseudo-random number generator (PRNG). Because of this, a network attacker who can estimate the virtual machine (VM) boot time can reconstruct a small list of possible passwords and recover the Administrator password, defeating the intended security control.

Impact Analysis

This vulnerability allows a network attacker to recover the local Administrator password by exploiting the predictable password generation process. Once the attacker recovers the Administrator password, they can gain unauthorized administrative access to the affected system. This compromises the security of the system by defeating the hardening control intended to protect the Administrator account.
