Summary

CVE-2019-25640 is a high-severity SQL Injection (CWE-89) vulnerability in Inoutscripts (inferred from references). Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.1th 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).

Deeper analysis

CVE-2019-25640 is an SQL injection vulnerability (CWE-89) in Inout Article Base CMS, affecting the portalLogin.php component. The flaw arises from insufficient sanitization of the 'p' and 'u' parameters in GET requests, enabling attackers to manipulate database queries with XOR-based payloads. Published on 2026-03-24, it carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating high severity due to network accessibility and confidentiality risks.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted GET requests to portalLogin.php. Successful exploitation allows extraction of sensitive database information or denial of service via time-based blind SQL injection techniques, with low attack complexity and no user interaction required.

Advisories and proof-of-concept exploits detail the issue, including an Exploit-DB entry at https://www.exploit-db.com/exploits/46593, the vendor product page at https://www.inoutscripts.com/products/inout-article-base/, and a VulnCheck advisory at https://www.vulncheck.com/advisories/inout-article-base-cms-lastest-sql-injection-via-portallogin-php. Practitioners should consult these for detection signatures, patch availability, or upgrade guidance from the vendor.

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.
T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
Why these techniques?

SQL injection in public-facing web application (portalLogin.php) directly enables exploitation of public-facing application (T1190) and facilitates data collection from databases via query manipulation (T1213.006).
