Summary

The D-Link DIR-620 devices, particularly those using specific customized firmware versions (1.0.3, 1.0.37, 1.3.1, 1.3.3, 1.3.7, 1.4.0, and 2.0.22), are susceptible to OS command injection due to improper handling of the res_buf parameter in index.cgi. This flaw may permit attackers to execute arbitrary OS commands, potentially compromising the device's integrity and exposing sensitive information on the network. Users of affected devices should urgently review their firmware and apply any security patches provided by D-Link to mitigate this risk.
