CVE-2025-54925 Overview
CVE-2025-54925 is a Server-Side Request Forgery (SSRF) vulnerability classified under [CWE-918]. The flaw allows an attacker who can configure the application to point at an attacker-controlled URL to coerce the server into issuing outbound requests on their behalf. Successful exploitation results in unauthorized access to sensitive data reachable from the server.
The issue is referenced in a Schneider Electric security notice and is exploitable over the network without authentication or user interaction. Confidentiality impact is high, while integrity and availability are unaffected.
Critical Impact
Unauthenticated attackers can abuse application-configured URL fetching to reach internal services and exfiltrate sensitive data accessible to the vulnerable host.

Technical Details for CVE-2025-54925
Vulnerability Analysis
The vulnerability is a Server-Side Request Forgery weakness in an application configuration path. The application accepts a URL value as part of its configuration and subsequently performs server-side requests to that URL without sufficient validation of the destination.
Because the request originates from the server, attacker-supplied URLs can target resources that are not directly reachable from the public network. These include internal HTTP services, cloud instance metadata endpoints, and other back-end systems that trust the host. Responses returned to the attacker may include sensitive data.
The attack vector is network-based, requires no privileges, and does not require user interaction. The impact is limited to confidentiality, with no direct write or denial-of-service consequences described.
Root Cause
The root cause is missing or insufficient validation of user-controllable URL configuration values before the server initiates outbound requests. The application does not enforce an allow-list of permitted hosts, schemes, or network ranges, allowing requests to arbitrary destinations including internal IP space and loopback addresses.
Attack Vector
An attacker with the ability to set the URL configuration value provides a destination pointing at an internal or sensitive resource. The vulnerable application then issues an HTTP request to that destination and returns or logs the response. The attacker uses this primitive to enumerate internal services, retrieve metadata, or harvest credentials reachable from the server.
No verified exploit code is publicly available. Refer to the Schneider Electric Security Notice for vendor-specific technical details.
Detection Methods for CVE-2025-54925
Indicators of Compromise
- Outbound HTTP or HTTPS requests from the application host to internal IP ranges such as 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, or loopback 127.0.0.1
- Requests from the application to cloud metadata endpoints such as 169.254.169.254
- Configuration changes that introduce unexpected external or non-standard URLs in the application settings
Detection Strategies
- Inspect application audit logs for modifications to URL-based configuration fields and correlate with the user account performing the change
- Monitor egress traffic from the application server for requests to non-business destinations or to RFC1918 addresses that the server should not contact
- Alert on HTTP requests originating from the server with response bodies containing tokens, keys, or metadata schema markers
Monitoring Recommendations
- Enable verbose logging on outbound HTTP client libraries used by the affected application
- Forward network flow data and application logs to a centralized analytics platform for correlation
- Establish a baseline of legitimate outbound destinations and alert on deviations
How to Mitigate CVE-2025-54925
Immediate Actions Required
- Apply the vendor-provided fix referenced in Schneider Electric advisory SEVD-2025-224-02
- Restrict administrative access to URL configuration fields to a minimal set of trusted operators
- Place the application behind an egress proxy that enforces an allow-list of permitted destinations
Patch Information
Consult the Schneider Electric Security Notice for the patched versions and remediation guidance applicable to your deployment.
Workarounds
- Block outbound traffic from the application host to internal network ranges and cloud metadata endpoints at the firewall
- Disable or restrict the application feature that fetches user-configured URLs if it is not required
- Audit existing URL configuration values and remove any entries that point to unexpected destinations
# Example egress filtering with iptables to block metadata and RFC1918 from app host

iptables -A OUTPUT -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -d 172.16.0.0/12 -j DROP
