CVE-2025-65230
📋 TL;DR
Barix Instreamer versions 04.06 and 04.05 contain a stored cross-site scripting vulnerability in the Web UI's Streaming Destination configuration input. This allows attackers to inject malicious scripts that execute when administrators view the configuration page. Organizations using these vulnerable versions are affected.
💻 Affected Systems
- Barix Instreamer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as administrators, or deploy malware to administrator browsers, potentially leading to full system compromise.
Likely Case
Attackers with access to the configuration interface could inject scripts that steal credentials or perform unauthorized actions when administrators view the page.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before execution, preventing exploitation.
🎯 Exploit Status
Exploitation requires access to the configuration interface. Public proof-of-concept available in GitHub repository.
