Lifecycle Timeline
2DescriptionCVE.org
A weakness has been identified in code-projects Nero Social Networking Site 1.0. This affects an unknown part of the file /friendprofile.php. Executing manipulation of the argument ID can lead to sql injection. It is possible to launch the attack remotely. The exploit has been made available to the public and could be exploited.
AnalysisAI
SQL injection in Nero Social Networking Site 1.0 exposes the /friendprofile.php endpoint to remote unauthenticated database manipulation via an unsanitized ID parameter. The CVSS 4.0 score of 5.5 reflects low-level confidentiality, integrity, and availability impact with no scope change to downstream systems. A public proof-of-concept exploit is available on GitHub, though the EPSS score of 0.03% (8th percentile) indicates negligible observed exploitation activity, consistent with the product's extremely narrow deployment footprint as a PHP demo application.
Technical ContextAI
Nero Social Networking Site 1.0 is a PHP-based demo social networking application developed by 'fabian' on code-projects.org (CPE: cpe:2.3:a:fabian:nero_social_networking_site:1.0). The vulnerability manifests in /friendprofile.php, where the ID parameter is incorporated into a backend SQL query without adequate sanitization or parameterization. The root cause is classified as CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), encompassing the SQL injection subclass (CWE-89). The flaw is a classic instance of unsanitized user-supplied input reaching a SQL interpreter, a pattern common in PHP applications that use direct string concatenation rather than PDO prepared statements or MySQLi parameterized queries. No framework or ORM protection is evident from available data.
RemediationAI
No vendor-released patch has been identified at time of analysis. Given the application's nature as a demo/educational project on code-projects.org, an official patch is unlikely to be released. Operators running this application should immediately restrict or remove public access to /friendprofile.php and consider decommissioning the application if it is internet-exposed, as production deployment of demo-grade software is strongly inadvisable. As a code-level fix, the ID parameter must be passed through PHP PDO prepared statements or MySQLi parameterized queries rather than string concatenation - this eliminates the injection vector without side effects. As a compensating control, deploying a WAF rule to block SQL metacharacters (single quotes, UNION, SELECT keywords) in the ID parameter can reduce opportunistic exploitation risk, though WAF bypasses are common for basic SQL injection payloads.
