CVE-2024-25948
📋 TL;DR
CVE-2024-25948 is an out-of-bounds write vulnerability in Dell iDRAC Service Module versions 5.3.0.0 and earlier. A privileged local attacker could execute arbitrary code, potentially causing denial of service. This affects systems running the vulnerable iDRAC Service Module software.
💻 Affected Systems
- Dell iDRAC Service Module
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Privileged local attacker gains arbitrary code execution with SYSTEM/root privileges, leading to complete system compromise, data exfiltration, or persistent backdoor installation.
Likely Case
Local attacker with administrative privileges causes denial of service by crashing the iDRAC Service Module, disrupting remote management capabilities.
If Mitigated
With proper access controls limiting local administrative privileges, impact is limited to denial of service from authorized administrators.
🎯 Exploit Status
Exploitation requires local privileged access. No public exploit code available at time of analysis.
