CVE-2026-24347
📋 TL;DR
Improper input validation in the Admin UI of EZCast Pro II version 1.17478.146 allows attackers to manipulate files in the /tmp directory. This vulnerability affects systems running the vulnerable version of EZCast Pro II software.
💻 Affected Systems
- EZCast Pro II
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could overwrite critical system files, execute arbitrary code, or achieve privilege escalation by manipulating files in the /tmp directory.
Likely Case
Attackers can create, modify, or delete temporary files, potentially leading to denial of service or data corruption.
If Mitigated
With proper input validation and file permission controls, impact is limited to non-critical temporary file manipulation.
🎯 Exploit Status
Exploitation requires access to the Admin UI interface and knowledge of the input validation flaw.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://hub.ntc.swiss/ntcf-2025-32806
Restart Required: Yes
Instructions:
1. Monitor vendor website for security updates. 2. Apply patch when available. 3. Restart affected services.
🔧 Temporary Workarounds
Restrict Admin UI Access
linuxLimit access to the Admin UI interface using firewall rules or network segmentation.
iptables -A INPUT -p tcp --dport [admin_port] -s [trusted_ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [admin_port] -j DROP
Secure /tmp Directory
linuxApply stricter permissions and mount options to the /tmp directory to limit file manipulation.
chmod 1777 /tmp
mount -o remount,noexec,nosuid /tmp
🧯 If You Can't Patch
- Implement network segmentation to isolate EZCast Pro II systems from critical infrastructure.
- Deploy application firewalls to monitor and block suspicious Admin UI requests.
🔍 How to Verify
Check if Vulnerable:
Check the software version via Admin UI or system logs for version 1.17478.146.Check Version:
grep -i version /var/log/ezcast.log || check Admin UI settings pageVerify Fix Applied:
Verify version has been updated beyond 1.17478.146 and test Admin UI input validation.📡 Detection & Monitoring
Log Indicators:
