** UNSUPPORTED WHEN ASSIGNED ** Draytek Vigor2960 v1.5.1.4 and v1.5.1.5 are vulnerable to directory traversal via the mainfunction.cgi dumpSyslog 'option' parameter allowing an authenticated attacker with access to the web management interface to delete arbitrary files. Vigor2960 is no longer supported.
DrayTek Vigor2960 v1.5.1.4 allows an authenticated attacker with network access to the web management interface to inject operating system commands via the mainfunction.cgi 'parameter' parameter. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
** UNSUPPORTED WHEN ASSIGNED ** A vulnerability classified as critical has been found in DrayTek Vigor 2960 1.5.1.4/1.5.1.5. Affected is the function sub_1DF14 of the file /cgi-bin/mainfunction.cgi of the component Web Management Interface. The manipulation of the argument option with the input /../etc/passwd- leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-221742 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
A Format String vulnerability exists in DrayTek Vigor 2960 <= 1.5.1.3, DrayTek Vigor 3900 <= 1.5.1.3, and DrayTek Vigor 300B <= 1.5.1.3 in the mainfunction.cgi file via a crafted HTTP message containing malformed QUERY STRING, which could let a remote malicious user execute arbitrary code.
A Remote Command Injection vulnerability exists in DrayTek Vigor 2960 1.5.1.3, DrayTek Vigor 3900 1.5.1.3, and DrayTek Vigor 300B 1.5.1.3 via a crafted HTTP message containing malformed QUERY STRING in mainfunction.cgi, which could let a remote malicious user execute arbitrary code.
On DrayTek Vigor3900, Vigor2960, and Vigor300B devices before 1.5.1, cgi-bin/mainfunction.cgi/cvmcfgupload allows remote command execution via shell metacharacters in a filename when the text/x-python-script content type is used, a different issue than CVE-2020-14472.
A stack-based buffer overflow on DrayTek Vigor2960, Vigor3900, and Vigor300B devices before 1.5.1.1 allows remote attackers to execute arbitrary code via the formuserphonenumber parameter in an authusersms action to mainfunction.cgi.
