phpMyAdmin CVE-2019-18622 SQL Injection Vulnerability

Description

phpMyAdmin is prone to an SQL-injection vulnerability because it fails to properly sanitize user-supplied input before using it in an SQL query. Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. phpMyAdmin versions prior to 4.9.2 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn’t needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
NIDS may identify and block generic attacks against web applications. Detecting and filtering SQL statements may reduce the likelihood of successful exploits.

Modify default ACL settings.
Implement database access control to limit the immediate impact of such vulnerabilities on the data and possibly the database itself. Ensure that applications are isolated from one another and from sensitive data through separate user accounts and restrictive ACL configurations.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Updates are available. Please see the references or vendor advisory for more information.
