Unauthenticated network endpoint with no complexity barrier; low C/I/A reflects limited scope of a single-purpose voting app database.

Lifecycle Timeline
1DescriptionCVE.org
A vulnerability was detected in code-projects Online Voting System 1.0. Impacted is the function test_input of the file /saveVote.php. Performing a manipulation of the argument voterName/voterEmail/voterID/selectedCandidate results in sql injection. The attack can be initiated remotely.
AnalysisAI
SQL injection in code-projects Online Voting System 1.0 exposes remote unauthenticated attackers a direct path to manipulate backend database queries through four parameters in the vote submission endpoint /saveVote.php. The test_input function - intended as a sanitization layer - fails to neutralize SQL metacharacters across voterName, voterEmail, voterID, and selectedCandidate, indicating a systemic rather than isolated input-handling failure. A publicly available proof-of-concept exists on GitHub, lowering the exploitation barrier, though real-world exposure is substantially constrained by the product's near-zero production deployment footprint as an educational PHP project.
Technical ContextAI
The affected application is a PHP-based voting system distributed by code-projects.org, a platform that publishes educational and demo source code projects. The vulnerable file /saveVote.php contains a function named test_input which performs superficial input handling but fails to prevent SQL injection - a textbook instance of CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses CWE-89 SQL Injection as a child weakness. The root cause is that user-supplied values are not bound through parameterized queries or prepared statements before being embedded in SQL logic. Four parameters are affected - voterName, voterEmail, voterID, and selectedCandidate - suggesting the unsanitized input pattern is applied broadly across the vote-processing logic rather than in one isolated location. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms the vulnerability is network-accessible with no authentication, no complexity barrier, and no required user interaction.
RemediationAI
No vendor-released patch has been identified at time of analysis - code-projects does not maintain security update cycles for its educational projects. The definitive fix is replacing the test_input function with PHP PDO or MySQLi prepared statements with bound parameters, which eliminates the SQL injection root cause entirely; this change must be applied consistently across all four vulnerable parameters in /saveVote.php. As a compensating control, web server access controls (e.g., Apache .htaccess or nginx allow/deny directives) can restrict /saveVote.php to known IP ranges, reducing unauthenticated exposure - though this breaks the application's intended public accessibility and is not a substitute for code-level remediation. Deploying a WAF rule blocking SQL metacharacter patterns in POST body parameters offers partial mitigation but can be bypassed with encoding techniques. The most effective long-term resolution is replacing this application with an actively maintained alternative. Advisory reference: https://vuldb.com/vuln/376162.
