Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 15 Apr 2022. US federal agencies had to remediate by 6 May 2022, a deadline that has passed.

Required action. Apply updates per vendor instructions.

Description

On certain Ubiquiti devices, Command Injection exists via a GET request to stainfo.cgi (aka Show AP info) because the ifname variable is not sanitized, as demonstrated by shell metacharacters. The fixed version is v4.0.1 for 802.11 ISP products, v5.3.5 for AirMax ISP products, and v5.4.5 for AirSync firmware. For example, Nanostation5 (Air OS) is affected.
