DrayTek VigorSwitch Multiple Models Buffer Overflow via poe_schedule_profile

Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the poe_schedule_profile function. The vulnerability is caused by repeated concatenation of the start_date, start_time, duration_time, how_often, weekdays, monthly_date, and cycle_duration fields into small fixed-size buffers without proper length checks. A remote attacker can trigger this vulnerability via crafted input, causing a denial of service or potentially executing arbitrary commands. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models Buffer Overflow via webBackupAction

Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the webBackupAction function. The vulnerability is caused by repeated string concatenation of the pathN, valueN, key, and option fields into fixed-size stack buffers without total length checks. A remote attacker can trigger this vulnerability via crafted input, causing a denial of service or potentially executing arbitrary commands. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models Path Traversal via getSyslogFile

Multiple DrayTek VigorSwitch models contain a directory traversal vulnerability in the getSyslogFile function. The vulnerability is caused by insufficient validation of the option field. A remote attacker can trigger this vulnerability via crafted input containing path traversal sequences to access arbitrary files on the device. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models OS Command Injection via rebDevice

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the rebDevice function. The vulnerability is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models OS Command Injection via getDetail

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the getDetail function. The vulnerability is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models Pre-Authentication NULL Pointer Dereference via setget.cgi

Multiple DrayTek VigorSwitch models contain a pre-authentication null pointer dereference vulnerability in the setget.cgi interface. The vulnerability is caused by missing validation when the pass field is absent. A remote attacker can trigger this vulnerability via a crafted request to crash the service and cause a denial of service.

DrayTek VigorSwitch Multiple Models NULL Pointer Dereference via formlogout

Multiple DrayTek VigorSwitch models contain a null pointer dereference vulnerability in the formlogout function. The vulnerability is caused by missing checks for an empty or absent Cookie header before string handling. A remote attacker can trigger this vulnerability via a crafted request to crash the service and cause a denial of service. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models OS Command Injection via pingtrace

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the pingtrace function. The vulnerability is caused by insufficient validation of the host field before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

DrayTek VigorSwitch Multiple Models OS Command Injection via setTime

Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the setTime function. The vulnerability is caused by insufficient filtering of the username and password fields before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. Exploitation requires valid administrative credentials for the device's web management interface.

Draytek Vigor Routers firmware versions below 3.9.6/4.2.4, Access Points firmware versions below v1.4.0, Switches firmware versions below 2.6.7, and Myvigor firmware versions below 2.3.2 were discovered to use hardcoded encryption keys which allows attackers to bind any affected device to their own account. Attackers are then able to create WCF and DrayDDNS licenses and synchronize them from the website.
