CVE-2025-6793
📋 TL;DR
This vulnerability in Marvell QConvergeConsole allows unauthenticated remote attackers to delete arbitrary files and read sensitive information by exploiting a directory traversal flaw in the QLogicDownloadImpl class. Attackers can achieve SYSTEM-level access on affected installations. Organizations using vulnerable versions of Marvell QConvergeConsole are at risk.
💻 Affected Systems
- Marvell QConvergeConsole
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via deletion of critical system files, disclosure of sensitive configuration files and credentials, and potential ransomware deployment.
Likely Case
Data destruction through arbitrary file deletion, credential theft from configuration files, and service disruption.
If Mitigated
Limited impact if network segmentation prevents external access and proper file permissions restrict SYSTEM-level damage.
🎯 Exploit Status
Directory traversal vulnerabilities typically have low exploitation complexity; ZDI advisory suggests weaponization is likely.
