CVE-2024-29730: SportsNET SQL Injection Vulnerability

CVE-2024-29730 Overview

CVE-2024-29730 is a SQL injection vulnerability affecting SportsNET version 4.0.1. The flaw resides in the idCat parameter of the /app/ax/consejoRandom/ endpoint. Attackers can send specially crafted SQL queries through this parameter without authentication. Successful exploitation allows attackers to retrieve, modify, and delete arbitrary data in the backend database.

The vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command). It is remotely exploitable over the network and requires no user interaction or privileges. The Spanish National Cybersecurity Institute (INCIBE) coordinated the disclosure of this issue.

Critical Impact
Unauthenticated network attackers can extract, alter, or destroy the contents of the SportsNET database through a single crafted HTTP request.

Technical Details for CVE-2024-29730

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw in the web application layer of SportsNET 4.0.1. The application accepts the idCat parameter from client requests and incorporates the value directly into a backend SQL statement. Because input is not parameterized or sanitized, attackers can break out of the intended query context and append arbitrary SQL.

Exploitation occurs through HTTP requests to the /app/ax/consejoRandom/ endpoint. The attack requires no authentication, no privileges, and no user interaction. Once an attacker controls the SQL statement, they can issue SELECT, UPDATE, and DELETE operations across any table the application's database account can reach.

Impact extends beyond data theft. Attackers can corrupt application state, destroy records, or pivot to authentication tables to forge or escalate access. In deployments where the database user holds broad privileges, the attacker effectively controls the data tier.

Root Cause

The root cause is the absence of parameterized queries or input validation when handling the idCat request parameter. User-controlled input is concatenated into a SQL statement before execution, mapping directly to [CWE-89].

Attack Vector

An unauthenticated remote attacker sends an HTTP request to the vulnerable endpoint /app/ax/consejoRandom/ with a malicious payload in the idCat parameter. The injected SQL is executed by the backend database engine with the privileges of the application's database account. No code or proof-of-concept exploit is publicly listed in NVD or ExploitDB at the time of publication.

No verified exploit code is publicly available. Refer to the INCIBE Security Notice for additional technical context.

Detection Methods for CVE-2024-29730

Indicators of Compromise

HTTP requests to /app/ax/consejoRandom/ containing SQL meta-characters such as single quotes, --, UNION, SELECT, OR 1=1, or ; within the idCat parameter.
Anomalous database errors or 500-level responses originating from the consejoRandom endpoint.
Unexpected UPDATE or DELETE statements in database audit logs targeting application tables.
Outbound responses with unusually large payloads from the affected endpoint, suggesting data exfiltration.

Detection Strategies

Deploy a web application firewall (WAF) rule set that inspects the idCat parameter for SQL injection signatures and tautology patterns.
Enable database query logging and alert on parameterized values containing SQL keywords or comment markers.
Correlate web server access logs with database audit logs to identify request-to-query mappings on the affected endpoint.

Monitoring Recommendations

Monitor the /app/ax/consejoRandom/ URI for spikes in traffic, repeated 4xx/5xx responses, or requests from a single source iterating over idCat values.
Track database accounts used by SportsNET for unusual DML activity, especially DELETE and UPDATE operations outside normal business hours.
Alert on outbound data transfer volumes from the application server that exceed historical baselines.

How to Mitigate CVE-2024-29730

Immediate Actions Required

Restrict network access to the SportsNET application to trusted users and networks until a vendor patch is applied.
Place a WAF in front of the application with rules blocking SQL injection patterns in the idCat parameter.
Reduce the privileges of the application's database account to the minimum required, removing DROP, ALTER, and broad DELETE rights where feasible.
Review database and application logs for prior exploitation attempts against /app/ax/consejoRandom/.

Patch Information

No vendor advisory or patch URL is listed in the NVD entry at the time of publication. Contact the SportsNET vendor for remediation guidance and consult the INCIBE Security Notice for disclosure details.

Workarounds

Block or filter requests to /app/ax/consejoRandom/ at the reverse proxy or WAF if the endpoint is not business-critical.
Enforce strict server-side validation on idCat, allowing only the expected data type (for example, a positive integer) before the value reaches the database layer.
Rotate database credentials used by the application and audit existing data for unauthorized modification.
