DescriptionCVE.org

A vulnerability was found in PHPGurukul News Portal Project 4.1. This affects an unknown part of the file /news-details.php. The manipulation of the argument Comment results in sql injection. The attack can be launched remotely. The exploit has been made public and could be used.

AnalysisAI

SQL injection in PHPGurukul News Portal Project 4.1 allows unauthenticated remote attackers to extract, modify, or delete database contents through the Comment parameter in /news-details.php. CVSS 7.3 severity with network-accessible attack vector requiring no authentication or user interaction. Publicly available exploit code exists. Attackers can compromise confidentiality, integrity, and availability of application data through crafted SQL payloads in comment submission functionality.

Technical ContextAI

CWE-89 SQL injection flaw stems from insufficient input validation on the Comment parameter in news-details.php. User-supplied comment data is incorporated into SQL queries without proper sanitization or parameterized statement usage, enabling direct database manipulation through malicious payloads. The unauthenticated attack vector (PR:N) and low complexity (AC:L) indicate trivial exploitation requiring only HTTP request manipulation.

RemediationAI

No vendor-released patch identified at time of analysis. Organizations should immediately implement input validation using prepared statements or parameterized queries for all database interactions in news-details.php. Apply strict allowlist-based filtering to Comment parameter accepting only alphanumeric characters and safe punctuation. Deploy web application firewall rules to block SQL metacharacters in POST/GET requests to /news-details.php. Consider disabling comment functionality until vendor releases security update. Monitor vendor advisory channels at https://phpgurukul.com/ and https://vuldb.com/vuln/356293 for patch availability. Implement principle of least privilege for database accounts used by the application to limit impact of successful exploitation.
