Description

A vulnerability classified as critical has been found in Linksys RE6500, RE6250, RE6300, RE6350, RE7000 and RE9000 1.0.013.001/1.0.04.001/1.0.04.002/1.1.05.003/1.2.07.001. This affects the function NTP of the file /goform/NTP. The manipulation of the argument manual_year_select/manual_month_select/manual_day_select/manual_hour_select/manual_min_select/manual_sec_select leads to os command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
