1. Vulnerability Assessment and Severity Evaluation

The EUVD entry EUVD-2024-26727 describes SQL injection vulnerabilities in SportsNET version 4.0.1. The vulnerability allows an attacker to execute arbitrary SQL queries by sending a specially crafted SQL query through the url parameter in the endpoint https://XXXXXXX.saludydesafio.com/app/ax/generateShortURL/.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector string breakdown is as follows:

• AV:N (Attack Vector: Network) - The vulnerability is exploitable over the network.
• AC:L (Attack Complexity: Low) - The attack requires low complexity.
• PR:N (Privileges Required: None) - No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None) - No user interaction is required.
• S:U (Scope: Unchanged) - The vulnerability does not change the security scope.
• C:H (Confidentiality: High) - The vulnerability has a high impact on confidentiality.
• I:H (Integrity: High) - The vulnerability has a high impact on integrity.
• A:H (Availability: High) - The vulnerability has a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject malicious SQL code into the url parameter to manipulate the database.
• Data Exfiltration: By crafting specific SQL queries, an attacker can retrieve sensitive information from the database.
• Data Manipulation: The attacker can update or delete database records, leading to data integrity issues.
• Denial of Service (DoS): The attacker can execute SQL commands that disrupt the normal operation of the database, causing a DoS condition.

Exploitation Methods:

• Manual Exploitation: An attacker can manually craft SQL queries and send them to the vulnerable endpoint.
• Automated Tools: Use of automated SQL injection tools to identify and exploit the vulnerability.
• Scripting: Writing scripts to automate the injection process and exfiltrate data.

3. Affected Systems and Software Versions

Affected Systems:

• SportsNET version 4.0.1

Software Versions:

• The vulnerability specifically affects version 4.0.1 of SportsNET.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by the vendor.
• Input Validation: Implement strict input validation and sanitization for the url parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.
