IBM Concert up to 2.2.0 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.

Summaryinfo

A vulnerability, which was classified as problematic, was found in IBM Concert up to 2.2.0. The affected element is an unknown function. The manipulation results in cryptographic primitive risky implementation. This vulnerability is reported as CVE-2025-64647. The attack can be launched remotely. No exploit exists. You should upgrade the affected component.

Detailsinfo

A vulnerability classified as problematic has been found in IBM Concert up to 2.2.0. Affected is some unknown functionality. 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. CVE summarizes:

IBM Concert 1.0.0 through 2.2.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information

The advisory is available at ibm.com. This vulnerability is traded as CVE-2025-64647 since 11/06/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 04/01/2026).

Upgrading eliminates this vulnerability.
