Vulnerability Assessment

Weakness	CWE CWE-89 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Parameterized queries, prepared statements MITRE ATT&CK 2 techniques across 2 tactics: Initial Access, Persistence The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Exploitation Conditions	Requires the attacker to reach the specific endpoint /reviewer_0/admins/assessments/pretest/exam-delete.php and supply a manipulated test_id parameter. Although the CVSS vector states PR:N (no authentication), the file resides in the /admins/ administrative area, so in a properly configured deployment a valid admin session is likely a practical prerequisite; exploitation is further limited by the product's rare deployment footprint (SourceCodester Online Reviewer Management System 1.0, a demo/student PHP+MySQL application).
Impact	This is a classic high-nominal/low-real-risk finding. The CVSS 4.0 base score of 6.9 (Medium) reflects a network-reachable, low-complexity SQL injection (AV:N/AC:L/AT:N), but VulDB deliberately scored the impact as only partial across all three dimensions (VC:L/VI:L/VA:L) rather than the VC:H typical of extractable SQLi, which caps the score. The vector embeds E:P (Proof-of-Concept), consistent with the publicly available exploit on GitHub - publicly available exploit code exists, but this is NOT active exploitation: there is no CISA KEV listing and no EPSS score was provided. The single most important mitigating signal is prevalence: SourceCodester projects are free student/demo PHP applications with essentially no production footprint, so despite an unauthenticated remote vector on paper, real-world exposure is minimal. NOTE A CONFLICT: the CVSS vector asserts PR:N (unauthenticated), yet the vulnerable file lives under an /admins/ administrative directory (/reviewer_0/admins/assessments/pretest/exam-delete.php), which normally implies an authenticated admin context - this discrepancy should be verified against the source code, as VulDB scoring for these submissions is frequently over-optimistic on PR.
Exploit ScenarioDerived	A remote attacker sends a crafted request to /reviewer_0/admins/assessments/pretest/exam-delete.php with a malicious test_id parameter, injecting SQL into the delete query to read, alter, or destroy database records. A public proof-of-concept is available on GitHub (huliangjia/cve issue #8), lowering the skill barrier, though the endpoint's placement under an admin path may require a valid session in a correctly deployed instance.

AnalysisAIv1 – Sep 23, 2026

SQL injection in SourceCodester Online Reviewer Management System 1.0 allows attackers to manipulate the test_id parameter in /reviewer_0/admins/assessments/pretest/exam-delete.php, potentially reading or altering database contents. Publicly available exploit code exists, but practical exploitation requires reaching the administrative interface and likely a valid admin session despite the CVSS 4.0 vector indicating no privileges; the product's rare deployment footprint further limits real-world risk. This is a classic high-nominal/low-real-risk finding with limited confidentiality, integrity, and availability impact.

RemediationAI

No vendor-released patch has been identified at the time of analysis. As a compensating control, restrict access to the /reviewer_0/admins/ directory to trusted administrators only, ensuring that strong authentication is enforced; this reduces the attack surface but may hinder legitimate administrative workflows. Additionally, implement input validation and parameterized queries in exam-delete.php to neutralize the SQL injection, though this requires custom code changes since the vendor has not provided an update. Consider deploying a web application firewall (WAF) to block malicious test_id parameters, but note that WAF rules can be bypassed with encoding tricks and require ongoing tuning. Given the product's demo/student nature and rare deployment, the most robust remediation is to remove the application from production environments or isolate it from untrusted networks. Monitor the vendor's website (https://www.sourcecodester.com/) and VulDB for any forthcoming patches.

Technical ContextAI · show details

The vulnerability is a SQL injection (CWE-89) in the PHP-based Online Reviewer Management System, specifically in the exam-delete.php script where the test_id parameter is passed to a SQL query without proper sanitization. The application likely uses MySQL as its backend database, and the affected endpoint resides within the administrative directory (/reviewer_0/admins/), meaning that in a properly configured deployment, an attacker would need a valid admin session to reach it. The CPE cpe:2.3:a:sourcecodester:online_reviewer_management_system:*:*:*:*:*:*:*:* indicates that all versions of the product are potentially affected, though only version 1.0 has been confirmed. The CVSS 4.0 vector shows a network-accessible attack with low complexity and no privileges required, but our independent assessment downgrades the privilege requirement to low (PR:L) due to the administrative context.
