Microsoft Windows up to Server 2025 Cryptographic Services cryptographic primitive risky implementation

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, was found in Microsoft Windows. This vulnerability affects unknown code of the component Cryptographic Services. The manipulation results in cryptographic primitive risky implementation. This vulnerability is identified as CVE-2025-58720. The attack is only possible with local access. There is not any exploit available. A patch should be applied to remediate this issue.

Detailsinfo

A vulnerability, which was classified as critical, was found in Microsoft Windows. Affected is some unknown functionality of the component Cryptographic Services. The manipulation with an unknown input leads to a cryptographic primitive risky implementation vulnerability. CWE is classifying the issue as CWE-1240. To fulfill the need for a cryptographic primitive, the product implements a cryptographic algorithm using a non-standard, unproven, or disallowed/non-compliant cryptographic implementation. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Use of a cryptographic primitive with a risky implementation in Windows Cryptographic Services allows an authorized attacker to disclose information locally.

The weakness was released 10/14/2025 as confirmed security update guide (Website). The advisory is available at msrc.microsoft.com. This vulnerability is traded as CVE-2025-58720. The exploitability is told to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 11/07/2025).

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-34319). If you want to get best quality of vulnerability data, you may have to visit VulDB.
