Lifecycle Timeline
4Description
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
Analysis
IBM Concert versions 1.0.0 through 2.2.0 implement cryptographic algorithms that are weaker than expected, allowing attackers to decrypt highly sensitive information without authentication. The vulnerability has a CVSS score of 5.9 with high confidentiality impact but no integrity or availability impact. A patch is available from IBM, and this represents a pure information disclosure risk affecting the confidentiality of encrypted data.
Technical Context
This vulnerability falls under CWE-1240 (Use of Insufficiently Trusted Data Source), which in this context refers to the use of cryptographic algorithms that do not provide adequate security strength. IBM Concert, an enterprise integration and orchestration platform, relies on cryptographic operations to protect sensitive configuration data, credentials, and inter-node communication. The weakness likely involves the use of deprecated or mathematically broken cryptographic primitives (such as weak key derivation functions, insufficient key lengths, or broken cipher suites) rather than modern standards like AES-256-GCM or ChaCha20-Poly1305. The affected CPE specification (cpe:2.3:a:ibm:concert:*:*:*:*:*:*:*:*) indicates all Concert products across all versions from 1.0.0 through 2.2.0 are impacted.
Affected Products
IBM Concert versions 1.0.0 through 2.2.0 are affected, as confirmed by CPE cpe:2.3:a:ibm:concert:*:*:*:*:*:*:*:*. All installations running any version within this range are vulnerable to decryption of sensitive data. IBM has released a patch available through their support portal at https://www.ibm.com/support/pages/node/7267105. Organizations should verify their current Concert version and cross-reference against the patched version number provided in the IBM security advisory.
Remediation
Upgrade IBM Concert to a patched version released after 2.2.0 as detailed in the IBM support advisory at https://www.ibm.com/support/pages/node/7267105. Until patching is completed, implement network-level controls including network segmentation to restrict Concert instances to trusted internal networks only, disable any unnecessary cryptographic data export features, and review access logs for evidence of unauthorized decryption attempts. If re-encryption of existing sensitive data with Concert is possible, perform a cryptographic key rotation using stronger algorithms after patching. Ensure that encrypted artifacts stored in backups or archives are inventoried and scheduled for re-encryption post-patch.
