IBM Concert 1.0-3.0 Weak Crypto Enables Decrypt
CVE-2026-6719 Published on October 19, 2026
IBM Concert Software Use of Insufficiently Random Values
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-2026-6719 can be exploited with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Type
Use of Insufficiently Random Values
The software uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. When software generates predictable values in a context requiring unpredictability, it may be possible for an attacker to guess the next value that will be generated, and use this guess to impersonate another user or access sensitive information.
