CVE-2025-50428
📋 TL;DR
This CVE describes a command injection vulnerability in RaspAP raspap-webgui that allows attackers to execute arbitrary commands on affected systems. The vulnerability affects users running RaspAP versions 3.3.2 and earlier, particularly those with web interface exposed. Attackers can exploit this by sending malicious input through the interface parameter.
💻 Affected Systems
- RaspAP raspap-webgui
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attacker to execute arbitrary commands with web server privileges, install malware, pivot to other systems, or establish persistent access.
Likely Case
Remote code execution leading to system takeover, data theft, or use as a foothold for further network attacks.
If Mitigated
Limited impact if proper network segmentation, least privilege, and input validation are implemented.
🎯 Exploit Status
Exploitation requires sending malicious input to the vulnerable parameter. Public references and pull requests demonstrate the vulnerability details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 3.3.2 (check latest release)
Vendor Advisory: https://github.com/RaspAP/raspap-webgui/pull/1833
Restart Required: Yes
Instructions:
1. Update RaspAP to latest version via git pull or package manager. 2. Restart web server service. 3. Verify the includes/hostapd.php file has proper input sanitization.
🔧 Temporary Workarounds
Disable web interface
linuxTemporarily disable the RaspAP web interface to prevent exploitation.
sudo systemctl stop lighttpd
sudo systemctl disable lighttpd
Network restriction
linuxRestrict access to RaspAP web interface using firewall rules.
sudo ufw deny 80
sudo ufw deny 443
sudo ufw allow from 192.168.1.0/24 to any port 80
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems
- Apply web application firewall (WAF) rules to block command injection patterns
🔍 How to Verify
Check if Vulnerable:
Check RaspAP version: cat /var/www/html/includes/config.php | grep 'RASPAP_VERSION' or check installed package version.Check Version:
grep 'RASPAP_VERSION' /var/www/html/includes/config.phpVerify Fix Applied:
Verify includes/hostapd.php contains proper input validation/sanitization and version is greater than 3.3.2.📡 Detection & Monitoring
