F5 BIG-IP AFM CVE-2019-6658 SQL Injection Vulnerability

Description

F5 BIG-IP AFM is prone to an SQL-injection vulnerability because it fails to sufficiently sanitize user-supplied input before using it in an SQL query. An attacker can exploit this issue to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

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.

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.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review logs regularly.

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

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