CVE-2024-10427: Pet Shop Management System SQLi Flaw

CVE-2024-10427 Overview

CVE-2024-10427 is a SQL injection vulnerability in Codezips Pet Shop Management System 1.0. The flaw exists in /deleteanimal.php, where the t1 parameter is passed to a database query without proper sanitization. Remote attackers with low-level privileges can manipulate the parameter to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the risk of opportunistic exploitation against exposed installations. The initial researcher advisory referenced the parameter as refno, but further inspection confirmed the affected parameter name is t1. This issue is categorized under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Authenticated remote attackers can execute arbitrary SQL queries against the backend database, potentially exposing or modifying pet shop records and customer data.

Technical Details for CVE-2024-10427

Vulnerability Analysis

The vulnerability resides in the /deleteanimal.php endpoint of Codezips Pet Shop Management System 1.0. The script accepts the t1 parameter from user-supplied input and concatenates it directly into a SQL DELETE statement. Because the application does not validate, sanitize, or parameterize the input, attackers can break out of the intended query context and append arbitrary SQL syntax.

The attack is initiated over the network and requires only low privileges on the application. No user interaction is needed to trigger the flaw. Successful exploitation allows attackers to read, modify, or delete records in the underlying database. Depending on database privileges, attackers may extract credentials, enumerate schema information, or pivot to additional records beyond the targeted animal entry.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. The deleteanimal.php script builds SQL queries through string concatenation with the t1 request parameter instead of using prepared statements or parameterized queries. Standard SQL injection payloads such as boolean conditions, UNION clauses, or stacked queries can be injected through this parameter.

Attack Vector

An attacker sends a crafted HTTP request to /deleteanimal.php with a malicious value supplied in the t1 parameter. The injected SQL is executed by the backend database engine in the context of the application's database user. Since the exploit has been publicly disclosed through VulDB and a GitHub issue, automated scanners and opportunistic attackers can readily weaponize the technique. Refer to the GitHub CVE Issue Discussion and VulDB #281968 for additional technical context.

Detection Methods for CVE-2024-10427

Indicators of Compromise

• HTTP requests to /deleteanimal.php containing SQL meta-characters in the t1 parameter, such as single quotes, UNION, SELECT, OR 1=1, or comment sequences like -- and #.
• Unexpected DELETE, UPDATE, or SELECT activity in MySQL query logs originating from the Pet Shop Management application user.
• Anomalous outbound responses with database error strings or large data exports from the application server.

Detection Strategies

• Inspect web server access logs for repeated or malformed requests to /deleteanimal.php containing URL-encoded SQL syntax.
• Deploy a web application firewall (WAF) with SQL injection signatures tuned to flag injection patterns in the t1 parameter.
• Correlate web application errors with database audit logs to identify queries that deviate from the application's expected query templates.

Monitoring Recommendations

• Enable MySQL general or audit logging on the database host to capture all queries executed via the application account.
• Alert on HTTP 500 responses from /deleteanimal.php that may indicate malformed injected payloads.
• Track sudden spikes in request volume against the deleteanimal.php endpoint from a single source address.

How to Mitigate CVE-2024-10427

Immediate Actions Required

• Restrict network access to the Pet Shop Management System administrative interfaces using firewall rules or VPN-only access.
• Place the application behind a WAF and enable SQL injection protection rules covering the t1 parameter on /deleteanimal.php.
• Audit the database account used by the application and remove unnecessary privileges such as FILE, DROP, or schema-level write access.

Patch Information

No official vendor patch has been published for Codezips Pet Shop Management System 1.0 at the time of disclosure. Operators should monitor the VulDB advisory and the vendor's distribution channels for an updated release. Until a fix is available, the application should be considered unsafe for exposure to untrusted networks.

Workarounds

• Modify /deleteanimal.php to use parameterized queries or prepared statements via mysqli or PDO instead of string concatenation.
• Apply server-side input validation to ensure the t1 parameter accepts only the expected numeric identifier format.
• Disable or remove the deleteanimal.php endpoint if the delete functionality is not required for operational use.
