CVE-2025-54924: Server-Side Request Forgery Vulnerability

CVE-2025-54924 Overview

CVE-2025-54924 is a Server-Side Request Forgery (SSRF) vulnerability (CWE-918) that could enable unauthorized access to sensitive data when an attacker sends a specially crafted document to a vulnerable endpoint. This vulnerability allows remote attackers to abuse server functionality to perform requests to internal resources or external systems, potentially exposing confidential information.

Critical Impact

Successful exploitation of this SSRF vulnerability could allow attackers to access sensitive internal data without authentication, potentially leading to information disclosure of protected systems and resources.

Technical Details for CVE-2025-54924

Vulnerability Analysis

This SSRF vulnerability exists within a document processing endpoint that fails to properly validate or sanitize user-supplied input before making server-side requests. The flaw allows an attacker to manipulate the application into making arbitrary HTTP requests to internal or external destinations of the attacker's choosing.

The vulnerability is particularly concerning because it requires no authentication or user interaction to exploit, and can be triggered remotely over the network. An attacker can craft malicious documents containing specially formed URLs or request parameters that, when processed by the vulnerable endpoint, cause the server to initiate requests to unintended targets.

Root Cause

The root cause of this vulnerability is improper input validation within the document processing functionality. The application fails to adequately validate, sanitize, or restrict the URLs and network resources that can be accessed when processing user-supplied documents. This allows attackers to specify arbitrary internal IP addresses, localhost references, or cloud metadata endpoints in their crafted documents.

Attack Vector

The attack vector for CVE-2025-54924 is network-based and does not require authentication or privileges. An attacker can exploit this vulnerability by:

1. Crafting a malicious document containing specially formed URLs pointing to internal resources
2. Submitting the crafted document to the vulnerable endpoint
3. The server processes the document and makes requests to the attacker-specified internal resources
4. Sensitive data from internal systems is returned to the attacker

This vulnerability is especially dangerous in cloud environments where attackers could access cloud metadata services (such as AWS EC2 metadata at 169.254.169.254) to retrieve credentials and other sensitive configuration data.

Detection Methods for CVE-2025-54924

Indicators of Compromise

• Unusual outbound requests from the application server to internal IP ranges (e.g., 10.x.x.x, 172.16.x.x, 192.168.x.x)
• Requests to localhost or loopback addresses (127.0.0.1, ::1) from document processing components
• Access attempts to cloud metadata endpoints such as 169.254.169.254
• Abnormal document uploads containing URL references to internal resources

Detection Strategies

• Monitor application logs for document processing requests containing internal IP addresses or suspicious URL patterns
• Implement network monitoring to detect outbound connections from application servers to internal-only resources
• Deploy web application firewall (WAF) rules to detect SSRF patterns in submitted documents
• Enable DNS query logging to identify requests for internal hostnames from the application server

Monitoring Recommendations

• Configure alerting for requests to cloud metadata service endpoints
• Implement egress filtering and monitor for bypass attempts
• Review document processing logs for anomalous URL patterns or excessive internal resource access
• Establish baseline network behavior for application servers and alert on deviations

How to Mitigate CVE-2025-54924

Immediate Actions Required

• Review the Schneider Electric Security Notice SEVD-2025-224-02 for specific remediation guidance
• Restrict network access to vulnerable endpoints until patches can be applied
• Implement network segmentation to limit the impact of potential SSRF exploitation
• Deploy web application firewall rules to block known SSRF attack patterns

Patch Information

Schneider Electric has published a security notice addressing this vulnerability. Refer to the Schneider Electric Security Notice SEVD-2025-224-02 for detailed patching instructions and affected product versions.

Workarounds

• Implement strict URL allowlisting for any document processing functionality
• Block outbound requests from application servers to internal IP ranges and cloud metadata endpoints
• Deploy network-level controls to prevent the application from accessing sensitive internal resources
• Consider disabling document processing functionality if not business-critical until patches are applied

# Example: Block SSRF attempts to cloud metadata endpoints using iptables
iptables -A OUTPUT -d 169.254.169.254 -j DROP

# Example: Restrict outbound connections to internal ranges
iptables -A OUTPUT -d 10.0.0.0/8 -j DROP
iptables -A OUTPUT -d 172.16.0.0/12 -j DROP
iptables -A OUTPUT -d 192.168.0.0/16 -j DROP
