CVE-2024-28976
📋 TL;DR
Dell Repository Manager versions before 3.4.5 contain a path traversal vulnerability in the API module. A local attacker with low privileges can exploit this to write arbitrary files to the server filesystem with web application privileges. This affects organizations using vulnerable versions of Dell Repository Manager.
💻 Affected Systems
- Dell Repository Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through arbitrary file writes leading to privilege escalation, remote code execution, or data destruction.
Likely Case
Unauthorized file writes allowing data manipulation, configuration changes, or planting backdoors for persistence.
If Mitigated
Limited impact if proper access controls and monitoring are in place, though file system integrity could still be compromised.
🎯 Exploit Status
Exploitation requires local access but low privileges; path traversal vulnerabilities are typically straightforward to exploit.
