CVE-2023-50956
📋 TL;DR
IBM Storage Defender - Resiliency Service versions 2.0.0 through 2.0.9 store secret keys containing user credentials in clear text. This allows privileged users to access sensitive authentication information that should be encrypted. The vulnerability affects organizations using these specific versions of IBM's storage management software.
💻 Affected Systems
- IBM Storage Defender - Resiliency Service
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
A malicious privileged user could extract all stored credentials, potentially gaining unauthorized access to protected systems and data, leading to data breaches or system compromise.
Likely Case
Privileged users could inadvertently or intentionally view sensitive credentials, violating security policies and potentially enabling credential reuse attacks.
If Mitigated
With proper access controls and monitoring, the risk is limited to authorized privileged users who would be audited and held accountable for any misuse.
🎯 Exploit Status
Exploitation requires existing privileged access to the system where the software is installed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.0.10 or later
Vendor Advisory: https://www.ibm.com/support/pages/node/7178587
