Title
TRENDnet TEW-821DAP NTP Timezone Configuration apply_time.cgi uci_safe_get stack-based overflow
Summary
A vulnerability was determined in TRENDnet TEW-821DAP 2.2.01b05. Affected by this vulnerability is the function uci_safe_get of the file /cgi-bin/apply_time.cgi of the component NTP Timezone Configuration Handler. Executing a manipulation of the argument system.ntp.server/system.ntp.enable_server/cameo.time.time_zone/cameo.cameo.syslog_server can lead to stack-based buffer overflow. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized.
