A denial of service vulnerability exists in the confctl_set_guest_wlan functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to denial of service. An attacker can send packets to trigger this vulnerability.

A stack-based buffer overflow vulnerability exists in the confsrv confctl_set_app_language functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to stack-based buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.

A stack-based buffer overflow vulnerability exists in the confers ucloud_add_node_new functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to stack-based buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.

An information disclosure vulnerability exists in the confctl_get_master_wlan functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to information disclosure. An attacker can send packets to trigger this vulnerability.

A denial of service vulnerability exists in the confctl_set_master_wlan functionality of TCL LinkHub Mesh Wifi MS1G_00_01.00_14. A specially-crafted network packet can lead to denial of service. An attacker can send packets to trigger this vulnerability.

A stack-based buffer overflow vulnerability exists in the confsrv addTimeGroup functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to a buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.

A hard-coded password vulnerability exists in the libcommonprod.so prod_change_root_passwd functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. During system startup this functionality is always called, leading to a known root password. An attacker does not have to do anything to trigger this vulnerability.

A denial of service vulnerability exists in the ucloud_del_node functionality of TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14. A specially-crafted network packet can lead to denial of service. An attacker can send packets to trigger this vulnerability.

An information disclosure vulnerability exists in the confctl_get_guest_wlan functionality of TCL LinkHub Mesh Wifi MS1G_00_01.00_14. A specially-crafted network packet can lead to information disclosure. An attacker can send packets to trigger this vulnerability.

This advisory documents the impact of an internally found vulnerability in Arista EOS for security ACL bypass. The impact of this vulnerability is that the security ACL drop rule might be bypassed if a NAT ACL rule filter with permit action matches the packet flow. This could allow a host with an IP address in a range that matches the range allowed by a NAT ACL and a range denied by a Security ACL to be forwarded incorrectly as it should have been denied by the Security ACL. This can enable an ACL bypass.
