CVE-2019-25713: MyT-PM SQL Injection Vulnerability

CVE-2019-25713 Overview

CVE-2019-25713 is an SQL Injection vulnerability in MyT-PM version 1.5.1 that allows authenticated attackers to execute arbitrary SQL queries through malicious input. The vulnerability exists in the Charge[group_total] parameter, enabling attackers to submit crafted POST requests to the /charge/admin endpoint. Successful exploitation can lead to unauthorized extraction of sensitive database information or manipulation of data through error-based, time-based blind, or stacked query injection techniques.

Critical Impact

Authenticated attackers can extract sensitive database contents, modify data, or potentially escalate privileges through SQL injection payloads targeting the charge management functionality.

Technical Details for CVE-2019-25713

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) in MyT-PM arises from insufficient input validation in the charge management module. The application fails to properly sanitize user-supplied input in the Charge[group_total] parameter before incorporating it into SQL queries. Because the vulnerability requires authentication, an attacker must first obtain valid credentials to the MyT-PM application before exploitation is possible. However, once authenticated, the attacker can leverage multiple injection techniques including error-based extraction, time-based blind injection, and stacked queries to interact with the underlying database.

The network-accessible nature of this vulnerability means that any authenticated user with access to the /charge/admin endpoint can potentially abuse this flaw. The impact includes high confidentiality risk due to the ability to extract sensitive data, along with some integrity risk from potential data manipulation capabilities.

Root Cause

The root cause of CVE-2019-25713 is improper input validation and lack of parameterized queries in the charge management functionality of MyT-PM. The Charge[group_total] parameter is directly concatenated into SQL statements without proper sanitization or escaping, allowing attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack is conducted over the network by an authenticated user. The attacker sends a malicious POST request to the /charge/admin endpoint with a crafted Charge[group_total] parameter containing SQL injection payloads.

The vulnerability can be exploited using several techniques:

• Error-based injection: Attackers can craft payloads that cause the database to return error messages containing sensitive data
• Time-based blind injection: By injecting time delay functions, attackers can infer database contents through response timing differences
• Stacked queries: Multiple SQL statements can be executed in a single request, potentially allowing data modification or deletion

Detailed exploitation information is available at Exploit-DB #46084.

Detection Methods for CVE-2019-25713

Indicators of Compromise

• Unusual POST requests to the /charge/admin endpoint with SQL syntax in the Charge[group_total] parameter
• Database error messages appearing in application logs or HTTP responses containing SQL keywords
• Abnormal database query patterns or execution times indicating time-based injection attempts
• Evidence of unauthorized data access or extraction from database audit logs

Detection Strategies

• Monitor web application logs for requests containing SQL keywords such as UNION, SELECT, OR 1=1, SLEEP(), or WAITFOR DELAY in POST parameters
• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the charge management functionality
• Enable database query logging and alert on queries with suspicious patterns or abnormally long execution times
• Deploy intrusion detection signatures for known SQL injection attack patterns against MyT-PM

Monitoring Recommendations

• Configure application-level logging to capture all requests to the /charge/admin endpoint with full POST body contents
• Establish baseline metrics for database query performance and alert on anomalies that may indicate time-based injection testing
• Monitor authentication logs for compromised accounts that may be used to launch authenticated attacks
• Review database access logs for unusual queries or access patterns from the web application user account

How to Mitigate CVE-2019-25713

Immediate Actions Required

• Restrict access to the /charge/admin endpoint to only trusted administrative users
• Implement a Web Application Firewall (WAF) with SQL injection detection rules in front of MyT-PM
• Review user accounts with access to the charge functionality and revoke unnecessary permissions
• Enable detailed logging for database queries and web requests to facilitate incident response

Patch Information

No official patch information is currently available from the vendor. Organizations should consult the ManageYourTeam Homepage for the latest security updates. For more details about the vulnerability and potential fixes, refer to the VulnCheck SQL Injection Advisory.

Workarounds

• Implement input validation at the web server or application proxy level to filter out SQL injection payloads before they reach the application
• Deploy a reverse proxy with ModSecurity or similar WAF capabilities configured with OWASP Core Rule Set to block SQL injection attempts
• If possible, modify the application code to use parameterized queries or prepared statements for all database interactions
• Consider network segmentation to limit which users can access the vulnerable endpoint
