CVE-2024-8762: Crud Operation System SQLi Vulnerability

CVE-2024-8762 Overview

CVE-2024-8762 is a SQL injection vulnerability in code-projects Crud Operation System 1.0. The flaw resides in the /updatedata.php script, where the sid parameter is passed to a database query without proper sanitization or parameterization [CWE-89]. Attackers can manipulate the sid argument to inject arbitrary SQL statements, allowing unauthorized read or modification of backend database content. The vulnerability is exploitable remotely over the network and requires only low-privileged access. Public disclosure of the exploit technique increases the likelihood of opportunistic attacks against exposed deployments.

Critical Impact

Remote attackers with low privileges can manipulate the sid parameter in /updatedata.php to execute arbitrary SQL queries, exposing or altering backend database content.

Affected Products

• code-projects Crud Operation System 1.0
• Deployments using the vulnerable /updatedata.php endpoint
• Web applications built on the unpatched Crud Operation System codebase

Technical Details for CVE-2024-8762

Vulnerability Analysis

The vulnerability is a SQL injection flaw [CWE-89] in the /updatedata.php component of code-projects Crud Operation System 1.0. The application accepts user-supplied input through the sid parameter and concatenates it directly into a SQL statement. This allows an attacker to break out of the intended query context and append arbitrary SQL syntax. Because the endpoint is reachable over the network, exploitation does not require local access or elevated permissions beyond a low-privileged session.

The affected functionality typically handles update operations against backend records. Injection at this point can return unintended rows, modify data integrity, or expose authentication-related fields. Public disclosure of the exploit means defenders should assume scanners and automated tooling will fingerprint this endpoint.

Root Cause

The root cause is the absence of parameterized queries or prepared statements when processing the sid request parameter. Input from the HTTP request flows directly into a SQL string without type enforcement, allow-list validation, or escaping. Any client able to reach /updatedata.php with authenticated context can supply malicious payloads in sid.

Attack Vector

An attacker sends a crafted HTTP request to /updatedata.php with a manipulated sid parameter containing SQL metacharacters and clauses. The injected statement is executed by the backend database with the privileges of the application's database user. Depending on the database role, the attacker can enumerate schema details, exfiltrate records via UNION-based or boolean-based techniques, or alter data through stacked queries.

The exploitation mechanism follows the standard SQL injection pattern against an unsanitized integer or string identifier. Refer to the GitHub Issue Tracker and the VulDB entry for additional technical context.

Detection Methods for CVE-2024-8762

Indicators of Compromise

• HTTP requests to /updatedata.php containing SQL metacharacters such as ', ", --, UNION, or SLEEP( in the sid parameter.
• Database error messages or HTTP 500 responses originating from /updatedata.php during parameter tampering.
• Unexpected UPDATE, SELECT, or INFORMATION_SCHEMA queries in database logs tied to the application's service account.

Detection Strategies

• Deploy web application firewall (WAF) signatures targeting SQL injection patterns against the /updatedata.php endpoint and the sid argument.
• Inspect application and database logs for malformed sid values, anomalous query structures, and repeated parsing errors.
• Correlate failed login or authorization events with subsequent injection attempts to identify reconnaissance behavior.

Monitoring Recommendations

• Enable verbose query logging on the database backend and alert on INFORMATION_SCHEMA access from the Crud Operation System service account.
• Monitor outbound network traffic from the database host for unusual data egress that may indicate dump-style exfiltration.
• Track request rate and parameter entropy on /updatedata.php to detect automated injection tooling such as sqlmap.

How to Mitigate CVE-2024-8762

Immediate Actions Required

• Restrict network access to /updatedata.php using authentication checks, IP allow-listing, or reverse proxy rules until a fix is applied.
• Apply WAF rules that block SQL metacharacters in the sid parameter and reject non-numeric values where appropriate.
• Audit database accounts used by the application and revoke unnecessary privileges such as FILE or schema-altering rights.

Patch Information

No official vendor patch has been published in the referenced advisories at the time of NVD publication. Maintainers and operators should review the GitHub Issue Tracker for upstream fixes and refactor /updatedata.php to use prepared statements with bound parameters before redeploying the application.

Workarounds

• Replace direct SQL string concatenation in /updatedata.php with PDO or mysqli prepared statements that bind sid as an integer.
• Add server-side input validation that enforces a strict numeric format on sid and rejects any non-conforming request.
• Run the application's database user with least-privilege permissions limited to the specific tables required by Crud Operation System.
