Description

Adversaries may attempt to get a listing of services running on remote hosts and local network infrastructure devices, including those that may be vulnerable to remote software exploitation.

Security Summary

CVE-2025-28091 is a Server-Side Request Forgery (SSRF) vulnerability, classified under CWE-918, affecting maccms10 version 2025.1000.4047. The issue arises via the Add Article functionality, allowing forged requests from the server side. It has a CVSS v3.1 base score of 9.1 (Critical), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, indicating network accessibility, low attack complexity, no privileges or user interaction required, unchanged impact scope, high confidentiality and integrity impacts, and no availability impact. The vulnerability was published on 2025-03-28.

Any unauthenticated attacker with network access can exploit this SSRF vulnerability remotely. By leveraging the Add Article feature, an attacker can trick the server into making unauthorized requests, potentially accessing internal services, bypassing firewalls, or interacting with resources not directly exposed to the internet. Successful exploitation enables high-level confidentiality breaches, such as reading sensitive data, and integrity violations, like modifying internal states, without disrupting availability.

MITRE ATT&CK Enterprise Techniques

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1046 Network Service Discovery Discovery
Adversaries may attempt to get a listing of services running on remote hosts and local network infrastructure devices, including those that may be vulnerable to remote software exploitation.
Why these techniques?

SSRF vulnerability in public-facing maccms10 Add Article feature enables remote unauthenticated exploitation of the application (T1190) and facilitates internal network service discovery by forging requests to non-public resources (T1046).
