This vulnerability allows remote attackers to execute arbitrary code on affected installations of Webmin. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of CGI requests. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root.

miniserv.pl in Webmin 1.962 on Windows mishandles special characters in query arguments to the CGI program.
software/apt-lib.pl in Webmin before 1.997 lacks HTML escaping for a UI command.
Webmin 1.973 is affected by reflected Cross Site Scripting (XSS) to achieve Remote Command Execution through Webmin's running process feature.
A Cross-Site Scripting (XSS) vulnerability exists in Webmin 1.973 via the Scheduled Cron Jobs feature.
Arbitrary command execution can occur in Webmin through 1.962. Any user authorized for the Package Updates module can execute arbitrary commands with root privileges via vectors involving %0A and %0C. NOTE: this issue exists because of an incomplete fix for CVE-2019-12840.
In Webmin through 1.910, any user authorized to the "Package Updates" module can execute arbitrary commands with root privileges via the data parameter to update.cgi.
Improper Access Control to Remote Code Execution in GitHub repository webmin/webmin prior to 1.990.
Webmin 1.973 is affected by Cross Site Request Forgery (CSRF) to achieve Remote Command Execution (RCE) through Webmin's running process feature.
rpc.cgi in Webmin through 1.920 allows authenticated Remote Code Execution via a crafted object name because unserialisevariable makes an eval call. NOTE: the WebminServersIndex documentation states "RPC can be used to run any command or modify any file on a server, which is why access to it must not be granted to un-trusted Webmin users."
Webmin 1.973 is affected by Cross Site Request Forgery (CSRF) to create a privileged user through Webmin's add users feature, and then get a reverse shell through Webmin's running process feature.
A Cross-site request forgery (CSRF) vulnerability exists in Webmin 1.973 via the Upload and Download feature.
A Cross-site request forgery (CSRF) vulnerability exists in Webmin 1.973 through the File Manager feature.
A cross-site request forgery (CSRF) vulnerability exists in Webmin 1.973 via the Scheduled Cron Jobs feature.
Webmin through 1.991, when the Authentic theme is used, allows remote code execution when a user has been manually created (i.e., not created in Virtualmin or Cloudmin). This occurs because settings-editorwrite.cgi does not properly restrict the file parameter.
Improper Authorization in GitHub repository webmin/webmin prior to 1.990.
Webmin 1.900 allows remote attackers to execute arbitrary code by leveraging the "Java file manager" and "Upload and Download" privileges to upload a crafted .cgi file via the /updown/upload.cgi URI.
Webmin before 2.202 and Virtualmin before 7.20.2 allow a network traffic loop via spoofed UDP packets on port 10000.
Multiple unspecified vulnerabilities in the Vsftpd Webmin module before 1.3b for the Vsftpd server have unknown impact and attack vectors related to "Some security issues."
xmlrpc.cgi in Webmin through 1.930 allows authenticated XXE attacks. By default, only root, admin, and sysadm can access xmlrpc.cgi.
Cross-site scripting vulnerability exists in sessionlogin.cgi of Webmin versions prior to 1.970 and Usermin versions prior to 1.820. If this vulnerability is exploited, an arbitrary script may be executed on the web browser of the user who accessed the website using the product. As a result, a webpage may be altered or sensitive information such as a credential may be disclosed.
Webmin before 1.860 has XSS with resultant remote code execution. Under the 'Others/File Manager' menu, there is a 'Download from remote URL' option to download a file from a remote server. After setting up a malicious server, one can wait for a file download request and then send an XSS payload that will lead to Remote Code Execution, as demonstrated by an OS command in the value attribute of a name='cmd' input element.
Multiple cross-site scripting vulnerabilities in Webmin versions prior to 1.830 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
XSS exists in Webmin 1.941 and earlier affecting the Save function of the Read User Email Module / mailboxes Endpoint when attempting to save HTML emails. This module parses any output without sanitizing SCRIPT elements, as opposed to the View function, which sanitizes the input correctly. A malicious user can send any JavaScript payload into the message body and execute it if the user decides to save that email.
A Cross-Site Scripting (XSS) vulnerability exists in Webmin 1.973 via the Upload and Download feature.
A Cross-Site Scripting (XSS) vulnerability exists in Webmin 1.973 through the File Manager feature.
A Cross-Site Scripting (XSS) vulnerability exists in Webmin 1.973 through the Add Users feature.
An issue was discovered in Webmin 2.021. A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the package search functionality. The vulnerability allows an attacker to inject a malicious payload in the "Search for Package" field, which gets reflected back in the application's response, leading to the execution of arbitrary JavaScript code within the context of the victim's browser.
