CVE-2024-2149 Overview
CVE-2024-2149 is a SQL injection vulnerability in CodeAstro Membership Management System 1.0. The flaw exists in settings.php, where the currency parameter is passed to a database query without proper sanitization. An authenticated attacker with high privileges can manipulate this parameter to inject arbitrary SQL statements. The attack is remotely exploitable over the network and does not require user interaction. The exploit has been publicly disclosed under identifier VDB-255502, increasing the likelihood of opportunistic exploitation against exposed instances.
Critical Impact
Successful exploitation allows attackers to read, modify, or delete sensitive database contents, including member records, credentials, and configuration data.
Affected Products
- CodeAstro Membership Management System 1.0
- Deployments exposing settings.php to authenticated users
- Instances relying on the currency request parameter without input filtering

Technical Details for CVE-2024-2149
Vulnerability Analysis
The vulnerability is a classic SQL injection issue [CWE-89] located in the settings.php component of CodeAstro Membership Management System 1.0. The application concatenates the value of the currency HTTP parameter directly into a SQL statement before executing it against the backend database. Because the parameter is neither validated nor bound as a prepared statement placeholder, attacker-controlled input alters the structure of the query.
An attacker with valid administrative credentials can submit crafted payloads through the settings interface. Payloads may include UNION SELECT statements to extract data, boolean-based blind techniques to enumerate schema, or stacked queries to modify records. The confidentiality, integrity, and availability of stored data are all at risk once the query context is broken.
Root Cause
The root cause is missing input sanitization and the absence of parameterized queries. The currency argument flows unchecked from the HTTP request into a SQL string, violating the separation between code and data. This is a common pattern in PHP applications that concatenate $_POST or $_GET values into query strings.
Attack Vector
The attack vector is network-based over HTTP or HTTPS. The attacker must first authenticate to the application with high-privilege credentials, then submit a modified request to settings.php containing a malicious currency value. Because no user interaction is required beyond the attacker's own request, exploitation can be scripted and automated once credentials are obtained.
No verified proof-of-concept code is available in the referenced advisories. See the GitHub CVE Hunting Guide and VulDB entry #255502 for additional technical context.
Detection Methods for CVE-2024-2149
Indicators of Compromise
- Unusual currency parameter values in HTTP requests to settings.php containing SQL keywords such as UNION, SELECT, SLEEP, or comment sequences (--, #).
- Database error messages returned in application responses following requests to the settings endpoint.
- Unexpected administrative actions or configuration changes originating from a single authenticated session.
Detection Strategies
- Deploy web application firewall rules that flag SQL metacharacters in the currency parameter for the affected endpoint.
- Enable database query logging and alert on syntactically malformed queries or queries referencing information_schema from application service accounts.
- Correlate authentication events with subsequent access to settings.php to identify credential misuse.
Monitoring Recommendations
- Monitor outbound data volume from the database server for signs of bulk extraction.
- Track administrative account activity for anomalous request patterns targeting configuration endpoints.
- Review web server access logs for repeated requests to settings.php with varying currency values, indicative of automated probing.
How to Mitigate CVE-2024-2149
Immediate Actions Required
- Restrict network access to the Membership Management System administrative interface using IP allowlisting or VPN gating.
- Rotate all administrative credentials and enforce multi-factor authentication for privileged accounts.
- Audit the database for unauthorized modifications and export activity dating back to the deployment of version 1.0.
Patch Information
No vendor patch has been published in the referenced advisories at the time of this writing. Organizations running CodeAstro Membership Management System 1.0 should contact the vendor for remediation guidance or evaluate migration to an alternative platform.
Workarounds
- Apply an input filter or WAF rule that rejects non-alphanumeric characters in the currency parameter before requests reach the application.
- Modify the application source to replace string concatenation in settings.php with parameterized queries using PDO or MySQLi prepared statements.
- Limit administrative accounts to the minimum number of trusted operators and revoke unused credentials.
