Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 32.2th 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

Web Ofisi Firma v13 is affected by CVE-2019-25457, an SQL injection vulnerability (CWE-89) in the 'oz' array parameter. This flaw allows attackers to inject malicious SQL code into database queries when processing GET requests to category pages. The vulnerability has 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 with low attack complexity and no privileges required.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted GET requests with malicious 'oz[]' values, such as time-based blind SQL injection payloads. Successful exploitation enables extraction of sensitive database information, potentially including user credentials, business data, or other confidential records hosted by the application.

Advisories and references, including an Exploit-DB proof-of-concept (https://www.exploit-db.com/exploits/47145) and a VulnCheck advisory (https://www.vulncheck.com/advisories/web-ofisi-firma-sql-injection-via-oz-parameter), detail the issue but do not specify patches or vendor-provided mitigations. The vendor product page (https://www.web-ofisi.com/detay/kurumsal-firma-v13-sinirsiz-dil.html) provides no remediation guidance in the available information. Security practitioners should isolate affected instances, apply input validation or prepared statements if customizing the software, and monitor for anomalous database queries.
