Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Contacts with security groups provide timely information on broken or risky cryptographic algorithms, reducing the likelihood of their selection and use.
Ongoing education and sharing of recommended practices helps organizations identify and migrate away from broken or risky cryptographic algorithms.
Cross-organization threat feeds commonly include advances in cryptanalysis and active exploits against weak or broken algorithms, allowing organizations to deprecate them proactively.
Capital planning and funding allow selection and ongoing support of strong cryptographic algorithms rather than weak or broken ones.
Risk updates surface newly-broken or risky cryptographic algorithms as threat intelligence and computing advances evolve, enabling timely replacement.
Scanners flag use of broken or weak cryptographic algorithms via known-vulnerability databases.
Enforces approved cryptographic algorithms for each use case, blocking use of broken or risky algorithms.
Flaw remediation replaces broken or risky cryptographic algorithms once safer implementations are released by vendors.
NVD Description
IBM Concert 1.0.0 through 2.1.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.
Deeper analysisAI
CVE-2024-43178 affects IBM Concert versions 1.0.0 through 2.1.0, where the software uses weaker than expected cryptographic algorithms. This vulnerability, classified under CWE-327 (Broken or Risky Cryptographic Algorithm), enables an attacker to decrypt highly sensitive information. The issue received a CVSS v3.1 base score of 5.9 (Medium severity), reflecting network accessibility with high attack complexity, no privileges or user interaction required, unchanged scope, high confidentiality impact, and no integrity or availability impact.
An unauthenticated attacker with network access can exploit this vulnerability by leveraging the weak cryptographic algorithms to decrypt sensitive data, though the attack requires high complexity to execute successfully. Successful exploitation would result in unauthorized access to highly sensitive information protected by the affected cryptography in IBM Concert.
