CVE-2024-7696
📋 TL;DR
This vulnerability allows authenticated attackers to tamper with audit logs or perform denial-of-service attacks on AXIS Camera Station servers by crafting malicious audit log entries. It affects organizations using vulnerable versions of AXIS Camera Station software. Attackers must have authenticated access to exploit this vulnerability.
💻 Affected Systems
- AXIS Camera Station
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete server unavailability through DoS attack, combined with audit log manipulation to hide malicious activities and disrupt forensic investigations.
Likely Case
Service disruption affecting camera monitoring capabilities, potentially combined with limited audit log tampering to conceal unauthorized access.
If Mitigated
Minimal impact with proper network segmentation, strong authentication controls, and monitoring in place to detect anomalous log activity.
🎯 Exploit Status
Exploitation requires authenticated access but appears straightforward based on the description of crafting malicious audit log entries.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in provided information - refer to Axis advisory
Vendor Advisory: https://www.axis.com/dam/public/b3/53/03/cve-2024-7696-en-US-459552.pdf
