The vulnerability in the inetipv6.cgi web interface of the DrayTek Vigor router software allows a attacker to trigger a Denial-of-Service Attack (DoS).

The vulnerability in the SSLapp.cgi web interface of the DrayTek Vigor router software lies in the overflow of buffers on the stack during the processing of the sIpv6AiccuUser parameter. Exploiting this vulnerability allows a remote attacker to trigger a Denial-of-Service attack...

The vulnerability of the web interface of Draytek Vigor routers, Draytek Vigor access points, Draytek Vigor switches, and the cloud platform Draytek Vigor Myvigor arises from the use of rigidly encrypted credentials. This allows attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the web interface of Draytek Vigor routers, Draytek Vigor access points, Draytek Vigor switches, and the cloud platform Draytek Vigor Myvigor is related to the use of rigidly encrypted login credentials. Exploiting this vulnerability allows a malicious actor to compromise the...

The vulnerability in the mainfunction.cgii web interface of DrayTek Vigor software allows a hacker to execute arbitrary code.

The vulnerability in the mainfunction.cgii web interface of the DrayTek Vigor router software exists due to the lack of measures taken to clean data at the control level. Exploiting this vulnerability allows an attacker operating remotely to execute arbitrary code...

The vulnerability of the set_ap_map_config() function in the mainfunction.cgi script of the DrayTek Vigor 3900, Vigor 2960, and Vigor 300B router microprogramming system allows a hacker to execute arbitrary commands.

The vulnerability of the setapmapconfig function in the mainfunction.cgi script of the DrayTek Vigor 3900, Vigor 2960, and Vigor 300B routers relates to the failure to eliminate the and & elements used in the operating system’s command when processing the action parameter. Exploiting this...
