DrayTek Vigor3910 devices through 4.3.2.6 are vulnerable to stored Cross Site Scripting (XSS) by authenticated users due to poor sanitization of the router name.
DrayTek Vigor3910 devices through 4.3.2.6 are vulnerable to reflected XSS by authenticated users, caused by missing validation of the sFormAuthStr parameter.
DrayTek Vigor3910 devices through 4.3.2.6 are affected by an OS command injection vulnerability that allows an attacker to leverage the recvCmd binary to escape from the emulated instance and inject arbitrary commands into the host machine.
A stack-based Buffer Overflow vulnerability in DrayTek Vigor310 devices through 4.3.2.6 allows a remote attacker to execute arbitrary code via a long query string to the cgi-bin/ipfedr.cgi component.
DrayTek Vigor3910 devices through 4.3.2.6 have a stack-based overflow when processing query string parameters because GetCGI mishandles extraneous ampersand characters and long key-value pairs.
DrayTek Vigor310 devices through 4.3.2.6 allow a remote attacker to execute arbitrary code via the function ft_payload_dns(), because a byte sign-extension operation occurs for the length argument of a _memcpy call, leading to a heap-based Buffer Overflow.
An issue in DrayTek Vigor310 devices through 4.3.2.6 allows an attacker to obtain sensitive information because the httpd server of the Vigor management UI uses a static string for seeding the PRNG of OpenSSL.
