CVSS v3.1 |
| 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. |
| Multiple DrayTek VigorSwitch models contain unauthorized operation vulnerabilities in multiple syslog functions. The vulnerability is caused by missing authorization checks. A remote attacker can trigger these vulnerabilities via crafted requests to modify configuration, restart services, save startup configuration, or clear logs. |
| Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the tftp_upgrade function. The vulnerability is caused by insufficient filtering before the filename field is concatenated into a command. 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. |
| Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the fdftDevice 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. |
| 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. |
| Multiple DrayTek VigorSwitch models contain a command injection vulnerability in the auth_set 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. |
| Multiple DrayTek VigorSwitch models contain a pre-authentication command injection vulnerability in the setget.cgi interface. The vulnerability is caused by insufficient filtering of the pass field before command execution. A remote attacker can trigger this vulnerability via crafted input to execute arbitrary commands with root privileges. |
| 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. |
| 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. |
| 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. |
