Technical Details for CVE-2025-48703
Vulnerability Analysis
The vulnerability arises from improper handling and sanitization of the t_total parameter within filemanager changePerm requests, allowing for arbitrary command execution when special shell metacharacters are injected.
Root Cause
The root cause lies in the lack of input validation and sanitization in the processing of user-supplied parameters within the filemanager component, making it susceptible to command injection.
Attack Vector
The attack vector for this vulnerability is over the network, requiring the attacker to have a valid non-root username to initiate the request.
# Example exploitation code (sanitized)
curl -X POST \
-d "action=changePerm&t_total=/;/bin/bash-c 'malicious_command'" \

Detection Methods for CVE-2025-48703
Indicators of Compromise
- Unexpected executions of shell commands from the application user
- Unusual outbound traffic or connections initiated to suspicious IPs
- Presence of new unauthorized user accounts
Detection Strategies
IDS/IPS solutions should be configured to monitor for anomalies in HTTP POST requests targeting sensitive endpoints. Analyze logs for unexpected command executions and deviations from normal behavior.
Monitoring Recommendations
Regularly review system logs for unauthorized activity. Utilize SentinelOne to detect unusual behavior and command executions indicative of exploitation attempts using AI-driven heuristic analysis.
How to Mitigate CVE-2025-48703
Immediate Actions Required
- Remove unnecessary access to the CWP panel from external networks
- Ensure all credentials are secure and rotate any potentially compromised passwords
- Apply application-level firewalls (WAF) configurations to prevent malicious inputs
Patch Information
Control Web Panel has released an update fixing this issue in version 0.9.8.1205. It is critical to apply this patch immediately to safeguard systems.
Workarounds
Isolate the CWP from direct internet access and utilize VPNs for administrative access to mitigate the risk of exploitation until patches can be applied.
# Configuration example
firewall-cmd --permanent --zone=public --add-source=trusted_ip
firewall-cmd --reload
