CVE-2021-20426Network attack vector

Sensitive-data disclosure via hard-coded credentials

Published May 24, 2021 · Updated Sep 16, 2024

Hard-coded credentials in IBM Security Guardium 11.2 allow remote attackers to read sensitive data through network access. IBM has not disclosed the credential value, its code or configuration locus, or whether the affected use is inbound authentication, outbound communication, or internal encryption. Exploitation requires no authentication or user interaction but depends on unspecified high-complexity conditions, and the documented impact is disclosure only.
