CVE-2025-30678 is a Server-Side Request Forgery (SSRF) vulnerability identified in the modTMSM component of Trend Micro Apex Central (on-premise) version 8.0. SSRF vulnerabilities occur when an attacker can manipulate server-side requests to interact with internal or external systems that the server can access, potentially bypassing network restrictions. In this case, the vulnerability allows an unauthenticated attacker (no privileges required) to manipulate certain parameters that control server requests, leading to unauthorized information disclosure. The vulnerability does not impact integrity or availability but has a high impact on confidentiality, as sensitive internal data could be exposed. The CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). No known exploits are currently reported in the wild, and no patches have been published at the time of analysis. The vulnerability is specific to the on-premise deployment of Trend Micro Apex Central version 8.0, a centralized security management platform widely used for endpoint and server security management. The SSRF flaw could allow attackers to leverage the server’s network access to retrieve sensitive information from internal resources or cloud metadata services, potentially facilitating further attacks or reconnaissance. Given the nature of the vulnerability, exploitation requires some user interaction, such as tricking a user into triggering a crafted request, which limits the attack vector somewhat but does not eliminate risk. The vulnerability is classified under CWE-918 (Server-Side Request Forgery).

For European organizations, the impact of this SSRF vulnerability in Trend Micro Apex Central could be significant, especially for enterprises relying on this product for centralized security management. Confidentiality breaches could expose sensitive internal network information, security configurations, or cloud metadata, which can be leveraged for lateral movement or privilege escalation. This could undermine the security posture of organizations, particularly those in regulated sectors such as finance, healthcare, and critical infrastructure, where data confidentiality is paramount. Since Trend Micro Apex Central is often deployed in hybrid environments managing endpoints and servers, attackers exploiting this vulnerability could gain insights into internal network topology or access tokens, increasing the risk of subsequent targeted attacks. The requirement for user interaction somewhat limits mass exploitation but targeted phishing or social engineering campaigns could be effective. The absence of known exploits currently reduces immediate risk but organizations should not delay remediation. The vulnerability does not affect system integrity or availability directly, so impact is primarily on information disclosure. However, the disclosed information could facilitate more damaging attacks later. European organizations with on-premise deployments of version 8.0 are at risk until patched or mitigated.

Apply vendor-provided patches immediately once available. Since no patches are currently published, monitor Trend Micro advisories closely for updates addressing CVE-2025-30678. Implement strict network segmentation to limit the Apex Central server’s access to sensitive internal resources and cloud metadata endpoints, reducing the potential impact of SSRF exploitation. Use web application firewalls (WAFs) or intrusion prevention systems (IPS) with rules tuned to detect and block SSRF attack patterns targeting the modTMSM component. Restrict and monitor outbound HTTP/HTTPS requests from the Apex Central server to only necessary destinations, employing egress filtering to prevent unauthorized internal or external requests. Educate users and administrators about the risk of social engineering or phishing that could trigger the SSRF vulnerability, emphasizing caution with unexpected links or requests related to Apex Central. Enable detailed logging and monitoring on Apex Central to detect unusual request patterns or anomalies indicative of SSRF attempts. Consider deploying virtual patching or temporary compensating controls if immediate patching is not feasible, such as disabling or restricting vulnerable functionality if possible. Review and harden configuration parameters related to modTMSM to ensure that parameters controlling server requests are validated and sanitized to the extent configurable.
