CVE-2024-8972: Saha365 App SQL Injection Vulnerability

CVE-2024-8972 Overview

CVE-2024-8972 is an SQL Injection vulnerability affecting the Mobil365 Informatics Saha365 App. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL queries into the application. This weakness (CWE-89) enables unauthorized database access, data manipulation, and potential complete system compromise.

Critical Impact

This SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands against the backend database, potentially leading to complete data breach, data manipulation, or denial of service.

Affected Products

• Mobil365 Informatics Saha365 App versions before 30.09.2024

Technical Details for CVE-2024-8972

Vulnerability Analysis

This SQL Injection vulnerability in the Saha365 App results from insufficient input validation and sanitization of user-supplied data before it is incorporated into SQL queries. When user input containing special SQL characters or commands is processed without proper neutralization, attackers can modify the intended query logic to access, modify, or delete database contents.

The network-accessible nature of this vulnerability means that exploitation can occur remotely without requiring authentication or user interaction. Successful exploitation could result in unauthorized access to sensitive information stored in the database, modification or deletion of data, and in some configurations, command execution on the underlying database server.

Root Cause

The root cause of CVE-2024-8972 is the improper neutralization of special elements in user-supplied input before constructing SQL queries. The application fails to properly sanitize or parameterize user input, allowing malicious SQL syntax to be interpreted as part of the database query rather than as data. This is a classic example of CWE-89 (SQL Injection), where the application concatenates untrusted data directly into SQL statements without proper escaping or using parameterized queries.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no privileges or user interaction to exploit. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable input fields or parameters in the Saha365 App. These payloads may include:

• Single quote characters (') to break out of string contexts
• SQL keywords like UNION, SELECT, INSERT, UPDATE, or DELETE
• Comment sequences (--, /**/) to neutralize trailing query portions
• Boolean-based or time-based blind injection techniques for data extraction

The vulnerability affects the application's interaction with its backend database, potentially exposing all stored data and database functionality to unauthorized manipulation.

Detection Methods for CVE-2024-8972

Indicators of Compromise

• Unusual database query patterns or errors in application logs
• Unexpected database access from web application service accounts
• Anomalous outbound data transfers from database servers
• Web application firewall (WAF) alerts for SQL injection attempts
• Database audit logs showing unauthorized data access or schema modifications

Detection Strategies

• Deploy web application firewalls (WAF) configured to detect and block SQL injection patterns
• Monitor application logs for SQL syntax errors or unusual query structures
• Implement database activity monitoring to detect anomalous query patterns
• Review HTTP request logs for common SQL injection payloads in request parameters

Monitoring Recommendations

• Enable detailed logging on web servers and database servers
• Configure alerting for SQL error messages appearing in application responses
• Monitor for mass data retrieval patterns that may indicate data exfiltration
• Implement intrusion detection systems (IDS) with SQL injection signature rules

How to Mitigate CVE-2024-8972

Immediate Actions Required

• Upgrade Saha365 App to version 30.09.2024 or later immediately
• Review application logs for signs of prior exploitation attempts
• Implement web application firewall rules to block SQL injection attacks
• Conduct a security assessment of the database for unauthorized modifications

Patch Information

Mobil365 Informatics has addressed this vulnerability in Saha365 App version 30.09.2024 and later. Organizations using affected versions should upgrade to the patched version as soon as possible. For additional details, refer to the USOM Security Notification TR-24-1890.

Workarounds

• Deploy a web application firewall (WAF) with SQL injection protection rules as a compensating control
• Implement input validation at the network perimeter using reverse proxy configurations
• Restrict database user privileges to limit potential impact of successful exploitation
• Consider temporarily taking the application offline if patching is not immediately possible and the risk is deemed critical
