CVE-2023-24958
📋 TL;DR
This vulnerability in IBM TS7700 Management Interface allows authenticated users to submit specially crafted URLs that can lead to privilege escalation and remote code execution. It affects IBM TS7700 Management Interface versions 8.51.2.12, 8.52.200.111, 8.52.102.13, and 8.53.0.63. Attackers with valid credentials could potentially gain full system control.
💻 Affected Systems
- IBM TS7700 Management Interface
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with administrative privileges, data exfiltration, ransomware deployment, and persistent backdoor installation across the TS7700 infrastructure.
Likely Case
Privilege escalation from authenticated user to administrator, followed by data access/modification, configuration changes, and potential lateral movement within the storage infrastructure.
If Mitigated
Limited to authenticated user access scope with proper network segmentation and monitoring preventing lateral movement and data exfiltration.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained. The CWE-78 (OS Command Injection) suggests direct command execution capability.
