CVE-2025-31551

Remediation/Mitigation Strategy: SQL Injection Vulnerability in Salesmate Add-On for Gravity Forms

Vulnerability Details:

  • Vulnerability ID: CVE-2025-31551
  • Affected Software: Salesmate.io Salesmate Add-On for Gravity Forms
  • Affected Versions: Versions n/a through 2.0.3
  • Vulnerability Type: Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)
  • Description: The Salesmate Add-On for Gravity Forms is susceptible to SQL Injection. This vulnerability allows an attacker to inject arbitrary SQL code into database queries, potentially leading to unauthorized access, data modification, or data deletion.

Severity:

  • CVSS Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Network, Low Attack Complexity, No Privileges Required, No User Interaction, Unchanged Scope, High Confidentiality Impact, High Integrity Impact, High Availability Impact)

Explanation of CVSS Metrics:

  • AV:N (Network): The vulnerability can be exploited over a network.
  • AC:L (Low Attack Complexity): The attack is easy to execute.
  • PR:N (None): No authentication is required to exploit the vulnerability.
  • UI:N (None): No user interaction is required to trigger the vulnerability.
  • S:U (Unchanged): An exploited vulnerability cannot affect resources beyond the security scope managed by the security authority of the vulnerable component.
  • C:H (High): There is a high impact to data confidentiality. An attacker can gain access to sensitive information.
  • I:H (High): There is a high impact to data integrity. An attacker can modify data.
  • A:H (High): There is a high impact to system availability. An attacker can disrupt or take down the application.

Known Exploit Information:

  • The provided data states “Awaiting Analysis” so details on the specific exploit vector are unknown, but we can infer based on the vulnerability type. Exploitation likely involves manipulating input fields within the Gravity Forms integration with Salesmate to inject malicious SQL code. This code could then be executed by the application’s database server.

Remediation/Mitigation Strategy:

Immediate Actions (Emergency Fixes):

  1. Update to a Patched Version: The most critical action is to update the Salesmate Add-On for Gravity Forms to a version higher than 2.0.3 if a patched version is available. Contact Salesmate.io or the plugin developer for confirmation on availability and instructions.
  2. Disable the Plugin (Temporary): As an immediate, albeit disruptive, measure, temporarily disable the Salesmate Add-On for Gravity Forms plugin until a patched version is available and deployed. This will prevent exploitation but will also break the integration.
  3. Web Application Firewall (WAF) Rules (Defense in Depth): Implement or update WAF rules to detect and block common SQL injection attack patterns. This is a defense-in-depth measure and should not be relied upon as the sole solution. Examples of rules could include:
    • Blocking requests containing SQL keywords like UNION, SELECT, INSERT, UPDATE, DELETE, DROP, etc. in input fields known to be used by the plugin.
    • Blocking requests with unusual characters or sequences that are not expected in normal input.

Long-Term Solutions (Permanent Fixes):

  1. Code Review and Security Audit: Conduct a thorough code review and security audit of the Salesmate Add-On for Gravity Forms to identify and address all potential SQL injection vulnerabilities. Focus on all code that handles user input and database interactions.
  2. Input Validation and Sanitization: Implement robust input validation and sanitization techniques to ensure that all user-supplied data is properly validated and sanitized before being used in SQL queries. This includes:
    • Whitelisting: Only allow specific characters or patterns in input fields.
    • Encoding: Encode special characters that could be interpreted as SQL commands.
  3. Parameterized Queries (Prepared Statements): Use parameterized queries (also known as prepared statements) instead of dynamically building SQL queries using string concatenation. Parameterized queries prevent SQL injection by treating user input as data, not as executable code.
  4. Least Privilege Principle: Ensure that the database user account used by the Salesmate Add-On for Gravity Forms has only the minimum necessary privileges required to perform its functions. Avoid granting the account overly broad permissions.
  5. Regular Security Updates: Establish a process for regularly updating the Salesmate Add-On for Gravity Forms and all other WordPress plugins to the latest versions to address security vulnerabilities as they are discovered. Subscribe to security advisories from Salesmate.io and Patchstack.
  6. Implement a Security Monitoring System: Implement a security monitoring system to detect and alert on suspicious activity, such as SQL injection attempts.

Testing:

  • Penetration Testing: Conduct thorough penetration testing after implementing the remediation steps to verify that the SQL injection vulnerability has been successfully addressed and that no other vulnerabilities exist.

Communication:

  • Inform Users: If the vulnerability has been exploited, inform users of potentially compromised data and recommend that they change their passwords.
  • Contact Salesmate.io: Contact Salesmate.io to report the vulnerability and request their assistance in developing and deploying a patch.

Important Considerations:

  • The information provided is based on the limited details from the vulnerability report. A full assessment requires a deeper dive into the Salesmate Add-On for Gravity Forms code.
  • This mitigation strategy is a starting point and should be tailored to the specific environment and requirements.
  • Implementing a combination of the above measures provides the strongest protection against SQL injection attacks.
