CVE-2020-22662: Ruckuswireless r310 firmware command injection vulnerability

Ruckuswireless · R310 Firmware

In Ruckus R310 10.5.1.0.199, Ruckus R500 10.5.1.0.199, Ruckus R600 10.5.1.0.199, Ruckus T300 10.5.1.0.199, Ruckus T301n 10.5.1.0.199, Ruckus T301s 10.5.1.0.199, SmartCell Gateway 200 (SCG200) before 3.6.2.0.795, SmartZone 100 (SZ-100) before 3.6.2.0.795, SmartZone 300 (SZ300) before 3.6.2.0.795, Virtual SmartZone (vSZ) before 3.6.2.0.795, ZoneDirector 1100 9.10.2.0.130, ZoneDirector 1200 10.2.1.0.218, ZoneDirector 3000 10.2.1.0.218, ZoneDirector 5000 10.0.1.0.151, a vulnerability allows attackers to change and set unauthorized "illegal region code" by remote code Execution command injection which leads to run illegal frequency with maxi output power. Vulnerability allows attacker to create an arbitrary amount of ssid wlans interface per radio which creates overhead over noise (the default max limit is 8 ssid only per radio in solo AP). Vulnerability allows attacker to unlock hidden regions by privilege command injection in WEB GUI.
