CVE-2025-30680 Overview
CVE-2025-30680 is a Server-Side Request Forgery (SSRF) vulnerability affecting Trend Micro Apex Central Software-as-a-Service (SaaS). The flaw lets an authenticated attacker manipulate certain request parameters to coerce the application into issuing unintended outbound requests. Successful exploitation leads to information disclosure on affected installations. The vulnerability is tracked under [CWE-918] and carries a CVSS 3.1 base score of 7.1. Trend Micro states that customers receiving automatic monthly maintenance releases on their SaaS instance require no further action.
Critical Impact
A low-privileged remote attacker can abuse the SSRF flaw to disclose sensitive information accessible to the Apex Central SaaS service, including internal resources reachable from the server.
Affected Products
- Trend Micro Apex Central (SaaS)
- Apex Central deployments running on Microsoft Windows
- SaaS instances not updated through Trend Micro's monthly maintenance releases

Technical Details for CVE-2025-30680
Vulnerability Analysis
The vulnerability resides in a request-handling component of Apex Central SaaS that accepts user-controlled input used to construct outbound HTTP requests. The application fails to validate or restrict the destination of these requests. An authenticated attacker with low privileges can supply crafted parameters that force the server to fetch attacker-chosen URLs. Because the request originates from the Apex Central server, it can reach internal endpoints and cloud metadata services not exposed to the public internet. The response content or behavior is then observable to the attacker, producing information disclosure.
Root Cause
The root cause is insufficient validation of URLs or host parameters consumed by a server-side fetch operation, classified as [CWE-918] Server-Side Request Forgery. The component does not enforce an allowlist of permitted destinations and does not block requests to internal address space, loopback, or link-local ranges. This permits arbitrary outbound HTTP requests under the identity of the Apex Central service.
Attack Vector
Exploitation requires network access to the Apex Central SaaS web interface and a valid low-privileged account. No user interaction is needed. The attacker sends an HTTP request containing manipulated parameters referencing internal targets. The Apex Central server processes the request and issues an outbound call on the attacker's behalf. Returned data or differential responses leak information about reachable hosts, services, or internal application state. Refer to the Zero Day Initiative Advisory ZDI-25-238 for additional technical context.

Detection Methods for CVE-2025-30680
Indicators of Compromise
- Outbound HTTP requests from the Apex Central application host to internal IP ranges, loopback, or cloud metadata endpoints such as 169.254.169.254.
- Unusual request parameters in Apex Central web logs containing fully qualified URLs, IP literals, or URL-encoded protocol handlers.
- Authenticated sessions from low-privilege accounts issuing repeated requests to endpoints that accept URL or host parameters.
Detection Strategies
- Monitor Apex Central web access logs for parameter values containing http://, https://, file://, or IP literals where a hostname is not expected.
- Correlate authenticated user activity with outbound network connections originating from the Apex Central server to non-Trend Micro destinations.
- Alert on responses to Apex Central HTTP requests that contain content lengths or status codes inconsistent with normal application behavior.
Monitoring Recommendations
- Enable detailed application and proxy logging on the Apex Central tier and forward logs to a centralized analytics platform for retention and correlation.
- Track per-account API usage patterns to identify low-privileged accounts probing parameters that drive server-side fetches.
- Establish a baseline of legitimate outbound destinations from Apex Central and alert on deviations.
How to Mitigate CVE-2025-30680
Immediate Actions Required
- Confirm that the Apex Central SaaS instance is enrolled in Trend Micro's automatic monthly maintenance release program.
- Review Apex Central account inventory and remove or restrict low-privileged accounts that are no longer required.
- Inspect recent web access and audit logs for evidence of SSRF probing activity prior to patch deployment.
Patch Information
Trend Micro has addressed CVE-2025-30680 in the Apex Central SaaS monthly maintenance release. Customers who allow Trend Micro to automatically apply monthly maintenance releases to their SaaS instance receive the fix without manual intervention. Refer to the Trend Micro Solution Overview KA-0019355 for vendor guidance.
Workarounds
- Restrict access to the Apex Central management interface to known administrative source networks where feasible.
- Enforce least-privilege role assignments so that only required accounts can reach endpoints that accept URL or host parameters.
- Apply egress filtering at the network boundary to block requests from the Apex Central host to internal address ranges and cloud metadata services.
# Example egress restriction concept (illustrative; adapt to your environment)
# Block outbound traffic from the Apex Central host to internal and metadata ranges
iptables -A OUTPUT -d 169.254.169.254 -j DROP
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
