CVE-2025-1156: Pix Software Vivaz SQL Injection Vulnerability

CVE-2025-1156 Overview

A critical SQL injection vulnerability has been identified in Pix Software Vivaz version 6.0.10. This vulnerability exists in the login servlet endpoint (/servlet?act=login) where the usuario parameter is susceptible to SQL injection attacks. The flaw allows remote attackers to manipulate SQL queries without authentication, potentially compromising the entire database backend. The exploit has been publicly disclosed, and notably, the vendor was contacted about this vulnerability but did not respond.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system.

Technical Details for CVE-2025-1156

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Injection) occurs in the authentication mechanism of Pix Software Vivaz. The login servlet at /servlet?act=login fails to properly sanitize or parameterize the usuario (username) input parameter before incorporating it into SQL queries. This classic injection flaw allows attackers to craft malicious input that alters the intended SQL query logic.

The vulnerability is particularly concerning because it affects the authentication endpoint, meaning attackers can potentially bypass login controls entirely or extract credentials and other sensitive information from the database. Since the attack requires no prior authentication and can be executed remotely over the network, it presents a significant risk to any internet-exposed deployment of this software.

Root Cause

The root cause is improper input validation and the use of unsanitized user input in SQL query construction. The application fails to implement parameterized queries (prepared statements) or adequate input sanitization for the usuario parameter in the login functionality. This allows user-supplied data to be interpreted as part of the SQL command structure rather than as data.

Attack Vector

The attack is executed remotely over the network by sending specially crafted HTTP requests to the vulnerable login endpoint. An attacker can manipulate the usuario parameter to inject SQL syntax that modifies the query behavior. Common attack scenarios include:

The vulnerable endpoint /servlet?act=login accepts the usuario parameter which is directly concatenated into SQL queries. An attacker can inject SQL metacharacters and commands to bypass authentication checks, enumerate database contents using UNION-based attacks, or extract data through blind SQL injection techniques. Since no authentication is required to reach the login page, this vulnerability can be exploited by any remote attacker with network access to the application.

Detection Methods for CVE-2025-1156

Indicators of Compromise

• Monitor HTTP request logs for suspicious SQL syntax patterns in the usuario parameter of requests to /servlet?act=login
• Look for unusual database query patterns or errors in application logs indicating SQL syntax errors
• Check for unexpected database access patterns such as bulk data extraction or unauthorized table enumeration
• Review authentication logs for successful logins with anomalous user identifiers

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the login endpoint
• Implement database activity monitoring to identify unauthorized queries or data exfiltration attempts
• Configure intrusion detection systems (IDS) to alert on SQL injection attack signatures in HTTP traffic
• Enable verbose logging on the application and database servers to capture exploitation attempts

Monitoring Recommendations

• Continuously monitor access logs for the /servlet?act=login endpoint for malicious payloads
• Set up alerts for database errors that may indicate SQL injection probing
• Implement rate limiting on the login endpoint to slow automated exploitation attempts
• Review database audit logs regularly for signs of unauthorized data access

How to Mitigate CVE-2025-1156

Immediate Actions Required

• Restrict network access to the Pix Software Vivaz application to trusted IP ranges only
• Deploy a Web Application Firewall (WAF) with SQL injection protection in front of the application
• If possible, disable or restrict access to the /servlet?act=login endpoint until a patch is available
• Implement additional authentication layers such as VPN requirements for accessing the application

Patch Information

As of the last update, no official patch has been released by the vendor. The vendor was contacted regarding this vulnerability but did not respond. Organizations using Pix Software Vivaz 6.0.10 should contact the vendor directly for remediation guidance or consider alternative solutions. For additional technical details, refer to VulDB Entry #295060 and the VulDB Submission #493482.

Workarounds

• Place the application behind a reverse proxy or WAF configured to filter SQL injection attempts
• Implement network segmentation to isolate the vulnerable application from critical systems
• Use database connection accounts with minimal required privileges to limit the impact of successful exploitation
• Consider implementing a custom input validation layer at the network perimeter to sanitize the usuario parameter

# Example WAF rule configuration (ModSecurity)
# Block SQL injection attempts on the login endpoint
SecRule REQUEST_URI "/servlet" "id:1001,phase:2,deny,status:403,chain"
SecRule ARGS:act "@streq login" "chain"
SecRule ARGS:usuario "@detectSQLi" "msg:'SQL Injection attempt blocked on Vivaz login'"
