CVE-2025-50228 Overview
Jizhicms v2.5.4 is vulnerable to Server-Side Request Forgery (SSRF) in the User Evaluation, Message, and Comment modules. This vulnerability allows attackers to manipulate the application server into making unauthorized requests to internal or external resources, potentially exposing sensitive internal services, bypassing access controls, or facilitating further attacks against backend infrastructure.
Critical Impact
SSRF vulnerabilities in Jizhicms v2.5.4 can allow attackers to access internal network resources, scan internal ports, and potentially exfiltrate sensitive data from backend services that should not be accessible from the public internet.

Technical Details for CVE-2025-50228
Vulnerability Analysis
The SSRF vulnerability in Jizhicms v2.5.4 exists within multiple user-facing modules including User Evaluation, Message, and Comment functionality. SSRF occurs when an application fetches remote resources based on user-supplied input without proper validation. In this case, attackers can craft malicious requests that cause the Jizhicms server to initiate connections to arbitrary internal or external destinations.
The vulnerability spans three distinct modules, suggesting a systemic issue with input validation and URL handling across the application's codebase. When exploited, the server acts as a proxy for the attacker, making requests on their behalf with the server's network privileges and trust relationships.
Root Cause
The root cause of this vulnerability stems from insufficient validation of user-supplied URLs or hostname parameters within the User Evaluation, Message, and Comment modules. The application accepts and processes URL inputs without adequately verifying the target destination, allowing attackers to redirect server-side requests to unintended internal resources, metadata endpoints, or external attacker-controlled servers.
Attack Vector
An attacker can exploit this SSRF vulnerability by submitting specially crafted URLs through the affected modules (User Evaluation, Message, or Comment). The attack typically involves:
- Identifying input fields that accept URLs or trigger server-side HTTP requests
- Submitting malicious URLs pointing to internal services (e.g., http://127.0.0.1, http://localhost, internal IP ranges, or cloud metadata endpoints like http://169.254.169.254/)
- The Jizhicms server processes the request and fetches the resource, returning data or confirming connectivity to the attacker
This can be leveraged to scan internal networks, access cloud instance metadata, interact with internal APIs, or pivot to attack other services. For detailed technical information regarding the vulnerability mechanism, refer to the GitHub Issue #104 Discussion.
Detection Methods for CVE-2025-50228
Indicators of Compromise
- Unusual outbound HTTP requests from the web server to internal IP addresses (e.g., 127.0.0.1, 10.x.x.x, 172.16.x.x, 192.168.x.x)
- Server-side requests to cloud metadata endpoints such as 169.254.169.254
- Unexpected network connections from the Jizhicms application to services it does not normally communicate with
- Log entries showing URL parameters containing internal hostnames or IP addresses in User Evaluation, Message, or Comment requests
Detection Strategies
- Implement network monitoring to detect anomalous outbound connections from the Jizhicms web server
- Configure web application firewall (WAF) rules to block requests containing internal IP addresses or suspicious URL patterns in user input
- Review application logs for URL parameters targeting localhost, private IP ranges, or cloud metadata services
- Deploy egress filtering to restrict the web server's ability to connect to internal network segments
Monitoring Recommendations
- Enable detailed logging for all HTTP requests made by the Jizhicms application
- Monitor for DNS queries to internal hostnames originating from the web server
- Set up alerts for failed or successful connections to internal services from the application tier
- Review access patterns in User Evaluation, Message, and Comment modules for anomalous URL submissions
How to Mitigate CVE-2025-50228
Immediate Actions Required
- Review and restrict user input fields in the User Evaluation, Message, and Comment modules that accept URLs
- Implement strict input validation to block internal IP addresses, localhost references, and cloud metadata endpoints
- Apply network segmentation to limit the web server's access to sensitive internal resources
- Monitor for exploitation attempts while awaiting an official patch
Patch Information
No official vendor patch has been confirmed at this time. Administrators should monitor the Official jizhicms Website and the GitHub Repository for jizhicms for security updates. It is recommended to track the GitHub Issue #104 Discussion for updates on this vulnerability.
Workarounds
- Implement a URL allowlist that permits only explicitly approved external domains for server-side requests
- Deploy a WAF with rules to detect and block SSRF attack patterns in request parameters
- Configure network-level egress rules to prevent the web server from accessing internal network ranges
- Consider temporarily disabling or restricting access to the affected modules (User Evaluation, Message, Comment) until a patch is available
- Use a forward proxy for all outbound requests from the application, allowing centralized URL filtering and logging
# Example: Network egress filtering using iptables to block internal network access from the web server
# Block access to common internal ranges from the web application user
iptables -A OUTPUT -m owner --uid-owner www-data -d 127.0.0.0/8 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 172.16.0.0/12 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 192.168.0.0/16 -j DROP
iptables -A OUTPUT -m owner --uid-owner www-data -d 169.254.169.254 -j DROP
