CVE-2026-18104: CWE-327 Use of a Broken or Risky Cryptographic Algorithm in IBM Db2 Mirror for i
IBM Db2 Mirror for i 7.6, 7.5, and 7.4 could allow a local attacker to obtain sensitive information due to the use of the AES Electronic Codebook (ECB) mode for encryption.
AI Analysis
Technical Summary
CVE-2026-18104 identifies a cryptographic weakness in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 where the AES encryption is implemented using the Electronic Codebook (ECB) mode. ECB mode is known to be insecure because it does not sufficiently randomize ciphertext blocks, potentially allowing attackers with local access to recover sensitive information. The vulnerability requires local access with low privileges and does not impact integrity or availability.
Potential Impact
A local attacker with low privileges could obtain sensitive information due to the insecure use of AES in ECB mode. The confidentiality impact is limited, and there is no impact on integrity or availability. No known exploits are reported in the wild.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is available, consider restricting local access to trusted users only to mitigate risk.
