DrayTek Vigor 2960 Web Management Interface mainfunction.cgi command injection

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability, which was classified as critical, was found in DrayTek Vigor 2960 1.5.1.4/1.5.1.5. Affected is an unknown function of the file mainfunction.cgi of the component Web Management Interface. The manipulation of the argument password leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-222258 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

An issue was discovered on certain DrayTek Vigor routers before July 2022 such as the Vigor3910 before 4.3.1.1. /cgi-bin/wlogin.cgi has a buffer overflow via the username or password to the aa or ab field.

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.

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.

An information disclosure vulnerability exists in Draytek VigorConnect 1.6.0-B3, allowing an unauthenticated attacker to export system logs.

The Profile Name field in the floor plan (Network Menu) page in Draytek VigorConnect 1.6.0-B3 was found to be vulnerable to stored XSS, as user input is not properly sanitized.

An arbitrary file deletion vulnerability exists in the file delete functionality of the Html5Servlet endpoint of Draytek VigorConnect 1.6.0-B3. This allows an authenticated user to arbitrarily delete files in any location on the target operating system with root privileges.

Draytek VigorConnect 1.6.0-B3 lacks cross-site request forgery protections and does not sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.

An arbitrary file upload and directory traversal vulnerability exists in the file upload functionality of DownloadFileServlet in Draytek VigorConnect 1.6.0-B3. An unauthenticated attacker could leverage this vulnerability to upload files to any location on the target operating system with root privileges.

Draytek VigorAP910C - Information Leakage

A vulnerable SNMP in Draytek VigorAP910C cannot be disabled, which may cause information leakage.

Draytek VigorAP 1000C contains a stored cross-site scripting (XSS) vulnerability in the RADIUS Setting - RADIUS Server Configuration module. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload in the username input field.

DrayTek Vigor2960 1.5.1 allows remote command execution via shell metacharacters in a toLogin2FA action to mainfunction.cgi.

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.

Stack-based buffer overflow vulnerability in Vigor3900, Vigor2960, and Vigor300B with firmware before 1.5.1.1.

On Draytek Vigor3900, Vigor2960, and Vigor 300B devices before 1.5.1.1, there are some command-injection vulnerabilities in the mainfunction.cgi file.

On DrayTek Vigor2925 devices with firmware 3.8.4.3, XSS exists via a crafted WAN name on the General Setup screen. NOTE: this is an end-of-life product.

On DrayTek Vigor2925 devices with firmware 3.8.4.3, Incorrect Access Control exists in loginset.htm, and can be used to trigger XSS. NOTE: this is an end-of-life product.

Cross-site scripting (XSS) vulnerability in DrayTek Vigor AP910C devices with firmware 1.2.0_RC3 build r6594 allows remote attackers to inject arbitrary web script or HTML via vectors involving home.asp.

Cross-site request forgery (CSRF) vulnerability in DrayTek Vigor AP910C devices with firmware 1.2.0_RC3 build r6594 allows remote attackers to hijack the authentication of unspecified users for requests that enable SNMP on the remote device via vectors involving goform/setSnmp.

In Draytek Vigor3900 1.5.1.3, attackers can inject malicious commands into mainfunction.cgi and execute arbitrary commands by calling the restore function.
