CVE-2025-30507
📋 TL;DR
CVE-2025-30507 is a blind SQL injection vulnerability in CyberData 011209 Intercom devices that allows unauthenticated attackers to extract sensitive information from the database. This affects organizations using these intercom systems for physical security or communication. The vulnerability enables data exfiltration without requiring valid credentials.
💻 Affected Systems
- CyberData 011209 Intercom
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive data including user credentials, configuration details, and potentially access to other systems through credential reuse or lateral movement.
Likely Case
Extraction of sensitive configuration data, user information, or system details that could facilitate further attacks or reconnaissance.
If Mitigated
Limited data exposure if proper network segmentation and input validation controls are in place, though some information leakage may still occur.
🎯 Exploit Status
Blind SQL injection typically requires automated tools for efficient exploitation but is well-understood by attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific version
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-25-155-01
