CVE-2024-5636: Bakery Online Ordering System SQLi Flaw

CVE-2024-5636 Overview

CVE-2024-5636 is a SQL injection vulnerability in itsourcecode Bakery Online Ordering System 1.0. The flaw exists in the report/index.php script, where the procduct parameter is passed to a backend SQL query without proper sanitization. An authenticated remote attacker can manipulate the parameter to inject arbitrary SQL statements against the application database. The issue is tracked in VulDB as identifier VDB-267092 and has been publicly disclosed with technical details available on GitHub. The weakness is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Remote attackers with low privileges can execute arbitrary SQL queries through the procduct parameter, leading to unauthorized read and write access to bakery ordering data.

Technical Details for CVE-2024-5636

Vulnerability Analysis

The vulnerability resides in the reporting module of the Bakery Online Ordering System. The script report/index.php accepts a request parameter named procduct and incorporates it directly into a SQL statement. Because the parameter is not validated, escaped, or bound through a prepared statement, attacker-controlled input alters the query syntax. This allows extraction of records, modification of stored data, and enumeration of the database schema. The flaw is reachable over the network and requires only low privileges to exploit, with no user interaction needed.

Root Cause

The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. The application concatenates the procduct HTTP parameter into a SQL query string rather than using parameterized queries. PHP code paths that build queries with string interpolation are inherently susceptible to injection when input filtering is absent.

Attack Vector

An attacker sends a crafted HTTP request to report/index.php with a malicious value in the procduct parameter. By appending SQL meta-characters and clauses such as UNION SELECT, OR 1=1, or time-based payloads, the attacker manipulates the underlying query. Public proof-of-concept material has been disclosed through the referenced GitHub CVE Analysis and VulDB entry, increasing the likelihood of opportunistic exploitation against exposed instances.

No verified exploit code is reproduced here. Refer to the public analysis linked above for parameter syntax and payload structure.

Detection Methods for CVE-2024-5636

Indicators of Compromise

• HTTP requests to /report/index.php containing SQL keywords such as UNION, SELECT, SLEEP(, or -- inside the procduct parameter.
• Web server access logs showing repeated requests to the report endpoint from a single source with varying procduct values.
• Unexpected database errors or anomalous query latency originating from the reporting module.

Detection Strategies

• Inspect web application firewall (WAF) and reverse proxy logs for SQL injection signatures targeting the procduct parameter.
• Enable verbose query logging on the backend database and alert on syntactically unusual queries originating from the application service account.
• Correlate authentication events with subsequent requests to report/index.php to identify low-privileged accounts probing the reporting feature.

Monitoring Recommendations

• Monitor for outbound data spikes from the database host that could indicate bulk record extraction.
• Alert on schema discovery queries against information_schema tables outside of expected administrative windows.
• Track 500-series HTTP responses from report/index.php, which often accompany failed injection attempts.

How to Mitigate CVE-2024-5636

Immediate Actions Required

• Restrict network access to the Bakery Online Ordering System until a fix is applied, exposing it only to trusted users.
• Audit report/index.php and replace string-concatenated SQL with parameterized queries using PDO or mysqli prepared statements.
• Review database audit logs for evidence of injection attempts and unauthorized data access since the application went live.

Patch Information

No official vendor patch has been published in the referenced advisories. Operators should apply source-level fixes by introducing input validation and prepared statements, or migrate to a maintained ordering platform. Consult the VulDB entry for further disclosure status.

Workarounds

• Deploy a WAF rule that rejects requests to /report/index.php when the procduct parameter contains SQL meta-characters such as quotes, semicolons, or comment sequences.
• Enforce server-side allow-list validation on procduct, restricting it to expected numeric or alphanumeric identifiers.
• Run the database service under a least-privilege account that cannot read or modify tables outside the application schema.
