CVE-2019-25457 in Firma
Summary
by MITRE • 02/22/2026
Web Ofisi Firma v13 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the 'oz' array parameter. Attackers can send GET requests to category pages with malicious 'oz[]' values using time-based blind SQL injection payloads to extract sensitive database information.

The vulnerability identified as CVE-2019-25457 resides within Web Ofisi Firma version 13, representing a critical security flaw that undermines the integrity of database operations through improper input validation. This issue manifests as an sql injection vulnerability that specifically targets the 'oz' array parameter utilized in category page requests, exposing the application to unauthorized data manipulation and extraction attempts by malicious actors. The flaw enables attackers to bypass authentication mechanisms entirely, as the vulnerability operates without requiring valid credentials or session tokens to exploit.
The technical implementation of this vulnerability follows a time-based blind sql injection methodology, where attackers construct malicious GET requests containing specially crafted 'oz[]' parameter values that trigger database response delays when processed. This approach relies on the database's behavior of pausing execution for specified time intervals when certain conditions are met, allowing attackers to infer database structure and content through timing analysis. The vulnerability stems from inadequate parameter sanitization and improper query construction practices, where user-supplied array values are directly incorporated into sql statements without proper escaping or parameterization.
From an operational impact perspective, this vulnerability presents significant risks to organizations utilizing Web Ofisi Firma v13, as it enables complete database compromise through unauthenticated access. Attackers can extract sensitive information including user credentials, personal data, business records, and system configurations through sequential time-based queries. The blind nature of the injection means that attackers must systematically test payloads and analyze response times to reconstruct database schemas, making the exploitation process more time-consuming but still highly effective. This vulnerability directly violates security principles outlined in cwe-89 sql injection and aligns with attack patterns described in the attack technique t1213 database server hijacking within the mitre att&ck framework.
Mitigation strategies for CVE-2019-25457 should prioritize immediate implementation of parameterized queries and input validation controls to prevent sql injection exploitation. Organizations must ensure that all user-supplied array parameters undergo rigorous sanitization before database processing, implementing proper escape sequences and using prepared statements to separate sql logic from data. Additionally, web application firewalls should be configured to monitor and block suspicious parameter patterns, while regular security audits should verify that all array inputs are properly validated against expected data types and ranges. The remediation process should also include updating to patched versions of Web Ofisi Firma, as this vulnerability represents a known flaw that has been addressed in subsequent releases, with the security community strongly recommending immediate patch deployment to prevent potential data breaches and compliance violations.
