IBM Concert Weak Crypto before 3.0.0 Decrypt Sensitive Data
CVE-2026-6930 Published on October 19, 2026
IBM Concert Software Risky Cryptographic Algorithm
IBM Concert 1.0 through 3.0.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.
Vulnerability Analysis
CVE-2026-6930 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is consided to have a high level of attack complexity. The potential impact of an exploit of this vulnerability is considered to have a small impact on confidentiality, a small impact on integrity and availability.
Weakness Type
Use of a Broken or Risky Cryptographic Algorithm
The use of a broken or risky cryptographic algorithm is an unnecessary risk that may result in the exposure of sensitive information. The use of a non-standard algorithm is dangerous because a determined attacker may be able to break the algorithm and compromise whatever data has been protected. Well-known techniques may exist to break the algorithm.
