Background

Ubiquiti UniFi is a Management Controller for Ubiquiti Networks UniFi APs.

Description

A bundled version of log4j could facilitate remote code execution. Please review the CVE identifier referenced below for details.

Impact

An attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.

Workaround

There is no known workaround at this time.

Resolution

All Ubiquity UniFi users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-wireless/unifi-6.5.55"
OSVersionArchitecturePackageVersionFilename
Gentooanyallnet-wireless/unifi< 6.5.55UNKNOWN
