CVE-2024-33958: E-negosyo System SQLi Vulnerability

CVE-2024-33958 Overview

CVE-2024-33958 is a SQL injection vulnerability in the Janobe Young Entrepreneur E-Negosyo System version 1.0. The flaw resides in the phonenumber parameter of the /passwordrecover.php endpoint. An unauthenticated attacker can send a crafted query to the server and retrieve information stored in the backend database. The issue is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command. INCIBE published the advisory covering multiple vulnerabilities in Janobe products.

Critical Impact

Unauthenticated remote attackers can extract sensitive data from the application database through the password recovery endpoint.

Technical Details for CVE-2024-33958

Vulnerability Analysis

The vulnerability stems from improper neutralization of user-supplied input in the password recovery workflow. The phonenumber parameter accepted by /passwordrecover.php is concatenated into a SQL statement without parameterization or input sanitization. An attacker can inject SQL syntax to alter the query logic and exfiltrate database contents.

Exploitation requires network access to the web application but no authentication and no user interaction. The Exploit Prediction Scoring System (EPSS) places this issue at the 48th percentile, indicating moderate likelihood of exploitation activity relative to the broader CVE corpus. No public proof-of-concept is currently listed, and the vulnerability is not present in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The root cause is the absence of prepared statements or input validation in the password recovery script. User input from the phonenumber field flows directly into a dynamic SQL query, allowing query structure manipulation through standard SQL injection payloads such as boolean-based, union-based, or time-based techniques.

Attack Vector

An attacker sends an HTTP request to /passwordrecover.php with a malicious phonenumber value. By appending SQL operators, the attacker can enumerate tables, dump credentials, or extract personally identifiable information. Because the endpoint is part of an unauthenticated password recovery flow, no prior account or session is required. Refer to the INCIBE Security Notice for additional context on the affected parameter and request structure.

Detection Methods for CVE-2024-33958

Indicators of Compromise

• HTTP requests to /passwordrecover.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the phonenumber parameter.
• Web server access logs showing unusually long or URL-encoded phonenumber values.
• Database error messages or HTTP 500 responses originating from the password recovery endpoint.
• Spikes in outbound data volume from the database host following requests to the password recovery flow.

Detection Strategies

• Deploy a Web Application Firewall (WAF) rule that inspects the phonenumber parameter for SQL injection signatures and OWASP CRS patterns.
• Enable database query logging and alert on queries originating from the password recovery flow that include UNION, INFORMATION_SCHEMA, or unexpected JOINs.
• Correlate web access logs with database audit logs to flag anomalous query patterns tied to a single source IP.

Monitoring Recommendations

• Monitor request rate and response size for /passwordrecover.php to identify enumeration or data exfiltration.
• Alert on repeated 4xx or 5xx responses from the password recovery endpoint from a single client.
• Track source IP reputation and geolocation for requests targeting authentication and recovery endpoints.

How to Mitigate CVE-2024-33958

Immediate Actions Required

• Restrict network access to the E-Negosyo System until a vendor fix is available.
• Place the application behind a WAF with SQL injection signatures enabled for the /passwordrecover.php endpoint.
• Audit database accounts used by the application and revoke unnecessary privileges, especially FILE and administrative roles.
• Review web and database logs for prior exploitation attempts against the phonenumber parameter.

Patch Information

No vendor patch has been published in the references available at the time of writing. Consult the INCIBE Security Notice for advisory updates and any future vendor remediation guidance.

Workarounds

• Disable or remove the /passwordrecover.php endpoint if the password recovery feature is not required.
• Implement server-side input validation to allow only numeric characters in the phonenumber field before any database interaction.
• Refactor backend queries to use parameterized statements or prepared queries through the application's database driver.
• Apply least-privilege principles to the database user account bound to the application.
