addresses: CWE-74

Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.

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.
Why these techniques?

Direct SQL injection in unauthenticated login.php of a publicly accessible web app enables remote exploitation of a public-facing application.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

A vulnerability was identified in code-projects Online Examination System 1.0. Affected by this issue is some unknown functionality of the file login.php. The manipulation of the argument username/password leads to sql injection. The attack may be initiated remotely.

Deeper analysisAI

CVE-2026-2173 is a SQL injection vulnerability (CWE-74, CWE-89) in code-projects Online Examination System 1.0. The flaw resides in an unknown functionality of the login.php file, where the username and password arguments can be manipulated to inject malicious SQL code. Published on 2026-02-08, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and low exploitation barriers.

Remote attackers require no privileges or user interaction to exploit this issue. By submitting crafted inputs to the username and password fields during login attempts, adversaries can execute arbitrary SQL queries, potentially leading to limited impacts on confidentiality (e.g., data exposure), integrity (e.g., data modification), and availability (e.g., denial of service).

Advisories from VulDB (ctiid.344874, id.344874, submit.749255) and the project site at code-projects.org provide further details; practitioners should consult these for any recommended patches, input validation fixes, or workarounds, as no specific mitigation steps are detailed in the CVE description.
