CVE-2019-25573
Published: 21 March 2026
Summary
CVE-2019-25573 is a high-severity SQL Injection (CWE-89) vulnerability in Njtech Greencms. Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.9th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2019-25573 is an SQL injection vulnerability (CWE-89) affecting Green CMS 2.x, rated with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N). The issue resides in the handling of the 'cat' parameter, where insufficient input sanitization allows injection of malicious SQL code via GET requests to index.php with the parameters m=admin, c=posts, and a=index.
Authenticated attackers with low privileges (PR:L) can exploit this vulnerability over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). By injecting SQL payloads into the 'cat' parameter, they can execute arbitrary SQL queries, manipulate database operations, and extract sensitive information, resulting in high confidentiality impact (C:H), low integrity impact (I:L), and no availability impact (A:N).
Advisories such as the VulnCheck entry (https://www.vulncheck.com/advisories/green-cms-2-x-sql-injection-via-cat-parameter) and a proof-of-concept exploit on Exploit-DB (https://www.exploit-db.com/exploits/46244) document the vulnerability in detail. Additional references include the official Green CMS site (http://www.greencms.net/) and its GitHub repository (https://codeload.github.com/GreenCMS/GreenCMS/zip/beta).
