Executive Summary

This vulnerability exists in IBM Concert versions 1.0.0 through 2.2.0, where the software uses weaker than expected cryptographic algorithms. Because of this weakness, an attacker could potentially decrypt highly sensitive information that should otherwise be protected.

Impact Analysis

The impact of this vulnerability is that an attacker might be able to decrypt highly sensitive information, which could lead to unauthorized access to confidential data. This could compromise the confidentiality of your information without affecting its integrity or availability.

Compliance Impact

The vulnerability involves the use of weaker than expected cryptographic algorithms in IBM Concert versions 1.0.0 through 2.2.0, which could allow an attacker to decrypt highly sensitive information.

Since GDPR, HIPAA, and similar regulations require strong protection of sensitive data, including encryption standards, this vulnerability could lead to non-compliance by failing to adequately protect sensitive information.

Organizations using affected versions of IBM Concert may risk violating these regulations due to potential exposure of sensitive data through cryptographic weaknesses.
