Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 43.7th 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-2019-25347, published on 2026-02-12, is a SQL injection vulnerability (CWE-89) in thesystem App version 1.0. The flaw resides in the authentication mechanism, where the username parameter is vulnerable to manipulation. Attackers can inject malicious SQL code, such as ' or '1=1', into the username field to bypass authentication controls and gain unauthorized access to user accounts.
The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), signifying exploitation over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows remote attackers to circumvent login protections, potentially accessing sensitive user data with high confidentiality impact but without affecting integrity or availability.
