CVE-2024-5069: Men's Salon Management System SQLi Flaw

CVE-2024-5069 Overview

CVE-2024-5069 is a SQL injection vulnerability in SourceCodester Simple Online Men's Salon Management System 1.0. The flaw resides in the view_service.php file, where the id parameter is passed directly into a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements and interact with the backend database. The vulnerability is remotely exploitable and requires only low-level privileges. Public disclosure of exploit details has occurred under VulDB identifier VDB-264926. The weakness is categorized as [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Remote attackers with low privileges can extract, modify, or delete database contents by injecting SQL through the id parameter of view_service.php.

Affected Products

• Oretnom23 (SourceCodester) Simple Online Men's Salon Management System 1.0
• Component: view_service.php
• Vulnerable parameter: id

Technical Details for CVE-2024-5069

Vulnerability Analysis

The vulnerability stems from unsafe handling of user-supplied input in view_service.php. The application accepts the id parameter via HTTP request and concatenates it directly into a SQL statement. Because the application performs no input validation, type casting, or parameterized querying, an attacker can append SQL syntax to alter the query logic. Successful exploitation allows extraction of stored salon data, customer records, administrator credentials, and other database contents. Depending on the database user's permissions, attackers may also modify or delete records. The flaw can be exercised remotely without user interaction.

Root Cause

The root cause is improper neutralization of special elements in an SQL command [CWE-89]. The id parameter consumed by view_service.php is interpolated into a SQL query without prepared statements or escaping. Any single quote, comment marker, or UNION clause supplied by the attacker becomes part of the executed query.

Attack Vector

The attack vector is network-based and requires authentication at a low privilege level. An attacker submits a crafted HTTP request to view_service.php with a malicious id value. Public exploit details are referenced in the GitHub SQL Injection Report and the VulDB entry #264926.

No verified exploit code is reproduced here. The vulnerability mechanism involves appending SQL operators such as UNION SELECT or boolean expressions to the id parameter to coerce the backend database into returning unauthorized data.

Detection Methods for CVE-2024-5069

Indicators of Compromise

• HTTP requests to view_service.php containing SQL metacharacters such as single quotes, --, /*, UNION, SELECT, or SLEEP in the id parameter.
• Unusually long or URL-encoded id parameter values in web server access logs.
• Database error messages or stack traces appearing in HTTP responses originating from view_service.php.
• Spikes in database query volume or unexpected SELECT statements against salon management tables.

Detection Strategies

• Inspect web server and application logs for anomalous query strings targeting view_service.php?id=.
• Deploy web application firewall (WAF) rules to flag classic SQL injection payload patterns against the affected endpoint.
• Enable database query auditing to capture queries originating from the salon management application and review for unexpected syntax.

Monitoring Recommendations

• Forward web server, application, and database logs to a centralized analytics platform for correlation.
• Alert on repeated HTTP 500 responses or database errors from view_service.php.
• Monitor for sudden bulk reads from sensitive tables such as user accounts or transaction records.

How to Mitigate CVE-2024-5069

Immediate Actions Required

• Restrict public exposure of the Simple Online Men's Salon Management System until remediation is complete.
• Place the application behind a WAF with SQL injection signatures enabled for the view_service.php endpoint.
• Audit accounts that have used the application and rotate credentials for any administrative database users.
• Review database contents for unauthorized modifications.

Patch Information

No official vendor patch has been published for SourceCodester Simple Online Men's Salon Management System 1.0 in the referenced advisories. Operators should consult the VulDB CTI entry #264926 and the VulDB submission #336842 for updates. Until a patch is provided, code-level remediation is required: replace string-concatenated queries in view_service.php with parameterized statements (prepared statements with bound parameters) and validate that the id parameter is a numeric value before use.

Workarounds

• Modify view_service.php to cast the id parameter to an integer before passing it to the SQL query.
• Implement prepared statements using PDO or MySQLi parameter binding throughout the codebase.
• Apply input allowlisting that rejects any non-numeric value submitted to the id parameter.
• Restrict the database account used by the application to the minimum privileges required, removing DROP, ALTER, and write access where not needed.
