Detailsinfo

A vulnerability classified as problematic was found in Cloud Foundry windows-utilities-release up to 0.22.x. Affected by this vulnerability is the function randomize_password of the component Administrator Password Handler. The manipulation with an unknown input leads to a weak prng vulnerability. The CWE definition for the vulnerability is CWE-338. The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong. As an impact it is known to affect confidentiality. The summary by CVE is:

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

The advisory is shared at cloudfoundry.org. This vulnerability is known as CVE-2026-41858 since 04/22/2026. The exploitation appears to be difficult. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.
