CVE-2019-25432
Published: 20 February 2026
Summary
CVE-2019-25432 is a high-severity SQL Injection (CWE-89) vulnerability. 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 26.8th 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-2019-25432 is an authentication bypass vulnerability in Part-DB version 0.4, stemming from SQL injection flaws in the login form's authentication parameters. Attackers can inject SQL syntax, such as a single quote followed by 'or', to bypass credential validation and gain unauthorized access to the application. The issue is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) with 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), indicating high confidentiality impact from network-accessible exploitation without privileges or user interaction.
Unauthenticated remote attackers can exploit this vulnerability by submitting malicious input into the login form, allowing them to log in without valid credentials and access sensitive application data. The low attack complexity enables straightforward exploitation, potentially leading to full compromise of the Part-DB instance depending on user permissions and deployed features.
Advisories and proof-of-concept exploits are available from sources including the Part-DB GitHub repository (https://github.com/Part-DB/Part-DB/), Exploit-DB (https://www.exploit-db.com/exploits/47547), and VulnCheck (https://www.vulncheck.com/advisories/part-db-authentication-bypass-via-loginphp), which detail the vulnerability and potential remediation steps such as upgrading to a patched version or implementing input sanitization.
