Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via mail_mailalert
Summary
Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the mail_mailalert function. The vulnerability is caused by concatenating multiple smtpReceiver email addresses into a fixed-size buffer without checking the remaining buffer size. 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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via acl_general_setup Edit ACE
Summary
Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the acl_general_setup Edit ACE function. The vulnerability is caused by copying the name field into a fixed-size buffer without length validation. 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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via switch_lan_gvrp
Summary
Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the switch_lan_gvrp function. The vulnerability is caused by unsafe copying of the portList field into an undersized buffer. 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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via poe_schedule_profile
Summary
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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via sysreboot
Summary
Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the sysreboot function. The vulnerability is caused by unsafe concatenation of split valueN data into a fixed-size buffer. 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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via webBackupAction
Summary
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.

Title
DrayTek VigorSwitch Multiple Models Buffer Overflow via pingtrace
Summary
Multiple DrayTek VigorSwitch models contain a buffer overflow vulnerability in the pingtrace function. The vulnerability is caused by missing length checks when the host, count, and interval fields are concatenated into a fixed-size buffer. 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.

Title
DrayTek VigorSwitch Multiple Models Path Traversal via getSyslogFile
Summary
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.

Title
DrayTek VigorSwitch Multiple Models OS Command Injection via setDevice
Summary
Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the setDevice function. The vulnerability is caused by insufficient sanitization of the username, password, and location 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.

Title
DrayTek VigorSwitch Multiple Models OS Command Injection via sysreboot
Summary
Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the sysreboot function. The vulnerability is caused by insufficient filtering of the config, act, pathN, and valueN 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.

Title
DrayTek VigorSwitch Multiple Models OS Command Injection via webBackupAction
Summary
Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the webBackupAction function. The vulnerability is caused by insufficient filtering of the option, key, pw_encode, pathN, and valueN 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.

Title
DrayTek VigorSwitch Multiple Models OS Command Injection via commandTable
Summary
Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the commandTable function. The vulnerability is caused by incomplete filtering of dangerous characters such as backticks, newline characters, and single quotes in the parameter field. 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.
