CVE-2026-12628

IBM Storage Protect hard-coded credentials

9.1 CRITICALEPSS 0.63%
  1. Published22 Jun 2026

Description

IBM Storage Protect Client 8.1.0.0 through 8.2.1.0 and IBM Storage Protect Snapshot For Windows 8.1.0.0 through 8.2.1.0 could allow a remote attacker to bypass authentication due to the use of a hardcoded credential in the FlashCopy Manager (FCM) authentication mechanism. The application contains a static credential embedded in multiple authentication code paths, and does not properly validate authentication responses, which may allow an unauthenticated attacker to establish a trusted session and access protected services. This vulnerability affects client components across multiple versions and may allow an attacker to impersonate legitimate clients, potentially leading to unauthorized access to system resources.
