CVE-2024-9011: Crud Operation System SQL Injection Flaw

CVE-2024-9011 Overview

CVE-2024-9011 is a SQL injection vulnerability in code-projects Crud Operation System 1.0. The flaw resides in the updata.php script, where the sid parameter is passed to a database query without proper sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements against the backend database. The issue requires only low-level privileges and no user interaction, and the exploit has been publicly disclosed. The weakness is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Remote attackers can inject SQL through the sid parameter in updata.php, exposing or modifying database contents in Crud Operation System 1.0.

Affected Products

• code-projects Crud Operation System 1.0
• Component: updata.php
• Vulnerable parameter: sid

Technical Details for CVE-2024-9011

Vulnerability Analysis

The vulnerability exists in the updata.php file of code-projects Crud Operation System 1.0. The sid request parameter is concatenated directly into a SQL query string without parameterized binding or input validation. Attackers supply crafted SQL fragments through sid to alter the structure of the executed query.

Successful exploitation allows reading, modifying, or deleting database records. Because the application accepts requests over the network, an authenticated low-privilege user can trigger the flaw remotely. A public proof-of-concept has been disclosed, lowering the barrier for opportunistic attackers.

The EPSS probability for CVE-2024-9011 is 0.105%, reflecting low predicted exploitation activity. However, public disclosure of the technique means defenders should treat the issue as actionable.

Root Cause

The root cause is unsanitized concatenation of the sid input into a SQL statement within updata.php. The application does not use prepared statements, parameter binding, or type enforcement on integer identifiers. This pattern matches [CWE-89] and reflects a missing input validation layer between the HTTP request handler and the database access code.

Attack Vector

The attack vector is network-based. An attacker sends an HTTP request to updata.php with a malicious value in the sid parameter. Typical payloads include boolean-based, union-based, or time-based blind SQL injection sequences targeting the underlying MySQL or MariaDB engine. No advanced tooling is required; the technique has been documented in the GitHub Issue Discussion and the VulDB entry #278166.

No verified exploit code is referenced in the NVD record. See the linked advisories for technical reproduction details.

Detection Methods for CVE-2024-9011

Indicators of Compromise

• HTTP requests targeting updata.php with SQL meta-characters in the sid parameter such as ', --, UNION, SELECT, or SLEEP(.
• Web server access logs showing repeated requests to updata.php from a single source with varying sid payloads.
• Database error messages or unusually long query response times correlated with traffic to updata.php.

Detection Strategies

• Inspect web application firewall (WAF) logs for SQL injection signatures hitting /updata.php?sid=.
• Enable database query logging and alert on syntactically anomalous statements referencing tables used by Crud Operation System.
• Correlate authentication events with subsequent abnormal database access patterns from the same session.

Monitoring Recommendations

• Forward web server, WAF, and database audit logs to a centralized analytics platform for SQL injection pattern matching.
• Baseline normal query structures issued by updata.php and alert on deviations such as nested SELECT statements or stacked queries.
• Track outbound data volumes from the database host to identify potential data exfiltration following injection attempts.

How to Mitigate CVE-2024-9011

Immediate Actions Required

• Restrict network access to the Crud Operation System application until a fix is applied, limiting exposure to trusted networks only.
• Deploy WAF rules that block SQL injection payloads on the sid parameter of updata.php.
• Audit existing database accounts used by the application and enforce least-privilege permissions to reduce blast radius.

Patch Information

No vendor patch is referenced in the NVD entry for CVE-2024-9011. Operators should monitor the code-projects website and the GitHub Issue Discussion for updated guidance. Until an official fix is released, apply the workarounds below.

Workarounds

• Modify updata.php to use parameterized queries or prepared statements for the sid value instead of string concatenation.
• Enforce server-side type validation that rejects any sid value that is not a positive integer before passing it to the database layer.
• Remove or disable the affected functionality if it is not required for production use.
• Place the application behind a reverse proxy with SQL injection filtering enabled.
