9.8CRITICAL
What is CVE-2022-35536?
WAVLINK routers, including models WN572HP3, WN533A8, WN530H4, WN535G3, and WN531P3, are vulnerable due to a lack of input validation in the QoS management interface. The parameters 'qos_bandwidth' and 'qos_dat' in the 'qos.cgi' file allow for command injection attacks, which could be exploited to execute arbitrary commands on the server. This vulnerability poses significant risks as it can lead to unauthorized control over the network devices, potentially compromising the entire network.
