CVE-2023-25925
📋 TL;DR
This vulnerability allows authenticated remote attackers to execute arbitrary operating system commands on IBM Security Guardium Key Lifecycle Manager systems by sending specially crafted requests. It affects versions 3.0 through 4.1.1 of the software. Attackers with valid credentials can potentially gain full control of affected systems.
💻 Affected Systems
- IBM Security Guardium Key Lifecycle Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attacker to execute arbitrary commands with system privileges, potentially leading to data theft, encryption key compromise, or deployment of ransomware.
Likely Case
Authenticated attacker gains command execution capabilities, allowing them to access sensitive key management data, modify configurations, or establish persistence on the system.
If Mitigated
With proper network segmentation and access controls, impact is limited to the specific Guardium Key Lifecycle Manager instance, though key management functions could still be disrupted.
🎯 Exploit Status
Requires authenticated access but exploitation appears straightforward based on CVSS score and CWE-78 (OS Command Injection).
