CVE-2024-8223: Music Gallery Site SQL Injection Flaw

CVE-2024-8223 Overview

CVE-2024-8223 is a SQL injection vulnerability in SourceCodester Music Gallery Site 1.0, developed by oretnom23. The flaw resides in the /classes/Master.php?f=delete_category endpoint, where the id parameter is passed unsanitized into a backend SQL query. Authenticated remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the risk of opportunistic abuse against exposed deployments. The weakness is tracked under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact
Remote attackers with low-privileged access can inject SQL through the id parameter of delete_category, leading to unauthorized read, modification, or deletion of database records.

Technical Details for CVE-2024-8223

Vulnerability Analysis

The vulnerability exists in the category deletion routine exposed through /classes/Master.php?f=delete_category. The handler accepts an id argument supplied by the client and concatenates it directly into a SQL statement. Because the input is neither parameterized nor escaped, attackers can break out of the intended query context and append arbitrary SQL clauses.

Successful exploitation can disclose database contents, alter records, or remove data from the underlying MySQL backend. The attack requires network reachability to the web application and low-level authentication on the site. Public technical analysis of the issue is available in the GitHub SQL Injection Analysis and the VulDB entry #275932.

Root Cause

The root cause is improper neutralization of user-supplied input before it is included in a SQL statement [CWE-89]. The delete_category function trusts the id argument from the HTTP request without enforcing a numeric type, prepared statements, or input validation. Any tainted characters such as quotes, comments, or UNION keywords reach the SQL engine intact.

Attack Vector

An attacker sends an HTTP POST or GET request to /classes/Master.php?f=delete_category and tampers with the id parameter. By injecting payloads such as boolean conditions, UNION SELECT clauses, or time-based delays, the attacker can enumerate schema metadata and exfiltrate user records. Since the endpoint is reachable over the network, exploitation can be automated against internet-exposed instances.

No verified proof-of-concept code is published in the NVD references beyond the analysis write-up. Refer to the VulDB CTI ID #275932 entry for additional context.

Detection Methods for CVE-2024-8223

Indicators of Compromise

HTTP requests to /classes/Master.php?f=delete_category containing SQL metacharacters such as ', --, UNION, SLEEP(, or INFORMATION_SCHEMA in the id parameter
Web server access logs showing repeated delete_category requests from the same source with varying id values
Unexpected MySQL errors or unusually long query response times correlated with category deletion requests

Detection Strategies

Deploy web application firewall (WAF) signatures that inspect the id parameter on the Master.php endpoint for SQL injection patterns
Enable database query logging and alert on queries originating from the delete_category code path that contain tautologies or stacked statements
Correlate authentication events with delete_category requests to identify low-privileged accounts probing the endpoint

Monitoring Recommendations

Monitor outbound database connections for anomalous bulk reads against the Music Gallery Site schema
Track failed login attempts followed by access to administrative PHP handlers in the /classes/ directory
Forward web and database logs to a centralized analytics platform for retention and threat hunting

How to Mitigate CVE-2024-8223

Immediate Actions Required

Restrict network access to Music Gallery Site 1.0 instances until a vendor-supplied fix is available
Disable or remove the delete_category endpoint if the feature is not required in production
Audit existing user accounts and rotate credentials for any account that could reach the vulnerable endpoint

Patch Information

No official vendor patch has been published in the referenced advisories at the time of NVD publication. Operators should track the SourceCodester project page and the VulDB submission #398722 for remediation updates. Until a patch is provided, apply compensating controls at the application and network layers.

Workarounds

Place the application behind a WAF with rules blocking SQL metacharacters in the id parameter of Master.php
Modify the delete_category handler to enforce strict integer casting of id and use parameterized queries via PDO::prepare or mysqli_prepare
Limit access to authenticated administrative users through IP allowlists or VPN-only access

bash

# Example mod_security rule blocking SQL metacharacters on the vulnerable endpoint
SecRule REQUEST_URI "@contains /classes/Master.php" \
    "chain,deny,status:403,id:1008223,msg:'CVE-2024-8223 SQLi attempt'"
    SecRule ARGS:id "@rx (?i)(union|select|sleep\(|--|;|')" "t:none"
