IBM Common Cryptographic Architecture 7.0.0 through 7.5.51 allows an authenticated user to cause a denial of service in the HSM via a specially crafted sequence of valid requests.
Vulnerability
IBM Common Cryptographic Architecture (CCA) versions 7.0.0 through 7.5.51 contain an out-of-bounds write vulnerability (CWE-787) in the Hardware Security Module (HSM) interface. An authenticated user can trigger this issue by sending a specially crafted sequence of valid requests to the CCA service, leading to a denial of service.
Exploitation
An attacker must be authenticated to the system and have network access (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). The exploit requires no user interaction and involves sending a specific sequence of valid CCA requests that cause an out-of-bounds memory write in the HSM firmware.
Impact
Successful exploitation results in a denial of service of the Hardware Security Module, causing high availability impact. No confidentiality or integrity loss is expected.
Mitigation
IBM has released security fixes for all affected versions; refer to the IBM security bulletin [1] for specific fix details and upgrade instructions. No workarounds are documented in the available references.
