CVE-2024-28979
📋 TL;DR
Dell OpenManage Enterprise versions 4.1.0 and older contain a cross-site scripting (XSS) vulnerability that allows high-privileged attackers with remote access to inject malicious scripts into web pages. This could lead to session hijacking, data theft, or unauthorized actions when users view compromised pages. Only administrators with valid credentials can exploit this vulnerability.
💻 Affected Systems
- Dell OpenManage Enterprise
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker could steal administrator session cookies, gain full control of the OpenManage Enterprise console, and potentially pivot to managed systems.
Likely Case
Attackers with valid credentials could inject scripts to steal session data or perform unauthorized actions within the management interface.
If Mitigated
With proper access controls and network segmentation, impact is limited to the management interface without affecting managed systems.
🎯 Exploit Status
Exploitation requires authenticated administrative access to the web interface.
