Summary

CVE-2025-56316 is a critical-severity SQL Injection (CWE-89) vulnerability in Mingsoft Mcms. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 34.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of unsanitized inputs like the content_title parameter to block arbitrary SQL query injection during FreeMarker template rendering.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of the specific SQL injection flaw in MCMS 5.5.0 via patching or code remediation.

SC-7 Boundary Protection partial match

preventdetect

Boundary protection at the network perimeter, such as web application firewalls, can inspect and block crafted SQL injection payloads sent to the /cms/content/list endpoint.

MITRE ATT&CK Enterprise TechniquesAI

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.

Why these techniques?

SQL injection in a public-facing web application endpoint directly enables T1190 (Exploit Public-Facing Application). Arbitrary SQL query execution facilitates T1213.006 (Data from Information Repositories: Databases) for unauthorized data access.

NVD Description

A SQL injection vulnerability in the content_title parameter of the /cms/content/list endpoint in MCMS 5.5.0 allows remote attackers to execute arbitrary SQL queries via unsanitized input in the FreeMarker template rendering.

Deeper analysisAI

CVE-2025-56316 is a SQL injection vulnerability (CWE-89) in MCMS 5.5.0, published on 2025-10-17. The flaw exists in the content_title parameter of the /cms/content/list endpoint, where unsanitized user input during FreeMarker template rendering enables remote attackers to execute arbitrary SQL queries. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting critical severity due to its network accessibility, low attack complexity, and lack of prerequisites.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted requests to the affected endpoint. Successful exploitation allows execution of arbitrary SQL queries, potentially resulting in high confidentiality, integrity, and availability impacts, such as unauthorized data access, modification, or system disruption.
