CVE-2025-46385: Server-Side Request Forgery Vulnerability

CVE-2025-46385 Overview

CVE-2025-46385 is a Server-Side Request Forgery (SSRF) vulnerability classified under CWE-918. This vulnerability allows attackers to manipulate server-side requests to access internal resources, bypass security controls, or interact with internal services that should not be externally accessible. SSRF vulnerabilities are particularly dangerous as they can be leveraged to pivot into internal networks and access sensitive data or systems.

Critical Impact

This SSRF vulnerability enables unauthorized network access with high integrity impact, allowing attackers to forge requests from the vulnerable server to internal or external resources without authentication requirements.

Technical Details for CVE-2025-46385

Vulnerability Analysis

This Server-Side Request Forgery (SSRF) vulnerability enables attackers to induce the server-side application to make HTTP requests to an arbitrary domain of the attacker's choosing. The vulnerability is exploitable remotely over the network without requiring any authentication or user interaction. The attack scope extends beyond the vulnerable component, meaning successful exploitation can impact resources outside the vulnerable system's security boundary.

The primary impact of this vulnerability is on data integrity, with the potential for attackers to modify or manipulate internal resources through forged requests. This could lead to unauthorized actions being performed on behalf of the server, data tampering in connected systems, or bypassing of network-based access controls.

Root Cause

The root cause stems from CWE-918: Server-Side Request Forgery, where the application fails to properly validate or sanitize user-supplied URLs or request parameters before making server-side HTTP requests. This allows attackers to control the destination of outbound requests made by the server, effectively using the application as a proxy to reach otherwise inaccessible resources.

Attack Vector

The attack vector is network-based with low complexity requirements. An attacker can exploit this vulnerability by:

1. Identifying input parameters that accept URLs or hostnames processed by the server
2. Supplying malicious URLs pointing to internal resources (e.g., http://localhost, http://169.254.169.254 for cloud metadata)
3. Leveraging the server's network position to access internal services, cloud provider metadata endpoints, or other restricted resources
4. Potentially chaining with other vulnerabilities to achieve further compromise

The vulnerability requires no privileges and no user interaction, making it highly exploitable in exposed applications.

Detection Methods for CVE-2025-46385

Indicators of Compromise

• Unusual outbound HTTP/HTTPS connections from application servers to internal IP ranges or localhost addresses
• Server requests to cloud metadata endpoints (e.g., 169.254.169.254, metadata.google.internal)
• Unexpected DNS resolution requests for internal hostnames from web-facing servers
• Log entries showing requests to internal-only services originating from the application layer

Detection Strategies

• Implement egress traffic monitoring to detect anomalous outbound requests from web servers
• Deploy Web Application Firewall (WAF) rules to inspect and block suspicious URL patterns in request parameters
• Monitor DNS query logs for resolution attempts of internal or suspicious hostnames from application servers
• Analyze application logs for URL parameters containing internal IP addresses, localhost references, or cloud metadata URLs

Monitoring Recommendations

• Enable comprehensive logging of all outbound HTTP requests made by server-side applications
• Configure network monitoring to alert on connections to internal IP ranges from DMZ or web-tier systems
• Implement application-level tracing to correlate user requests with server-side HTTP calls
• Set up alerts for access attempts to sensitive internal endpoints from application servers

How to Mitigate CVE-2025-46385

Immediate Actions Required

• Audit application code for user-controllable URL parameters used in server-side requests
• Implement strict allowlist validation for any URLs processed server-side
• Block outbound connections to internal IP ranges and cloud metadata endpoints from application servers
• Apply network segmentation to limit the reach of potential SSRF attacks

Patch Information

Patch information is not currently available in the CVE data. Security teams should monitor the Israeli Government CVE Advisories for updated remediation guidance and patch availability announcements.

Workarounds

• Implement URL allowlisting to restrict server-side requests to known-safe domains only
• Deploy network-level controls to prevent application servers from reaching internal resources or cloud metadata services
• Use a dedicated proxy server with strict egress filtering for all outbound requests
• Disable unnecessary URL-following functionality and limit HTTP redirect depth in server-side request handlers
• Consider implementing DNS pinning to prevent DNS rebinding attacks that may bypass validation

Organizations should implement defense-in-depth measures combining input validation, network segmentation, and monitoring to reduce SSRF risk while awaiting vendor patches.
