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.

Webmin before 2.202 and Virtualmin before 7.20.2 allow a network traffic loop via spoofed UDP packets on port 10000.

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.

Cross-site scripting vulnerability exists in sysinfo.cgi of Webmin versions prior to 1.910. 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 session ID may be obtained, a webpage may be altered, or a server may be halted.

Cross Site Scripting vulnerability (XSS) in webmin v.2.105 and earlier allows a remote attacker to execute arbitrary code via a crafted payload to the "Execute cron job as" tab Input field.

There is a stored cross-site scripting (XSS) vulnerability in Webmin 2.002 and below via the Cluster Cron Job tab Input field, which allows attackers to run malicious scripts by injecting a specially crafted payload.

A Stored Cross-Site Scripting (XSS) vulnerability in the mail forwarding and replies tab in Webmin and Usermin 2.000 allows remote attackers to inject arbitrary web script or HTML via the forward to field while creating a mail forwarding rule.

A Reflected Cross-site scripting (XSS) vulnerability in the file manager tab in Usermin 2.000 allows remote attackers to inject arbitrary web script or HTML via the replace in results field while replacing the results under the tools drop down.

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.

An issue was discovered in Webmin 2.021. The download functionality allows an attacker to exploit a Cross-Site Scripting (XSS) vulnerability. By providing a crafted download path containing a malicious payload, an attacker can inject arbitrary code, which is then executed within the context of the victim's browser when the download link is accessed.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Users and Groups functionality, allowing an attacker to store a malicious payload in the Group Name field when creating a new group.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the System Logs Viewer functionality. The vulnerability allows an attacker to store a malicious payload in the configuration field, triggering the execution of the payload when saving the configuration or when accessing the System Logs Viewer page.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the Users and Groups functionality. The vulnerability occurs when an authenticated user adds a new user and inserts an XSS payload into the user's real name.

An issue was discovered in Webmin 2.021. A Stored Cross-Site Scripting (XSS) vulnerability was discovered in the configuration settings of the system logs functionality. The vulnerability allows an attacker to store an XSS payload in the configuration settings of specific log files. This results in the execution of that payload whenever the affected log files are accessed.

An issue was discovered in Webmin 2.021. A Cross-site Scripting (XSS) Bypass vulnerability was discovered in the file upload functionality. Normally, the application restricts the upload of certain file types such as .svg, .php, etc., and displays an error message if a prohibited file type is detected. However, by following certain steps, an attacker can bypass these restrictions and inject malicious code.

An issue was discovered in Webmin 2.021. A Cross-Site Scripting (XSS) vulnerability was discovered in the HTTP Tunnel functionality when handling third-party domain URLs. By providing a crafted URL from a third-party domain, an attacker can inject malicious code. leading to the execution of arbitrary JavaScript code within the context of the victim's browser.

An issue was discovered in Webmin 2.021. One can exploit a stored Cross-Site Scripting (XSS) attack to achieve Remote Command Execution (RCE) through the Users and Group's real name parameter.

The Read Mail module in Webmin 1.995 and Usermin through 1.850 allows XSS via a crafted HTML e-mail message.

software/apt-lib.pl in Webmin before 1.997 lacks HTML escaping for a UI command.

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.

A Cross-site request forgery (CSRF) vulnerability exists in Webmin 1.973 through the File Manager 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.

A Cross-site request forgery (CSRF) vulnerability exists in Webmin 1.973 via the Upload and Download feature.

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 via the Scheduled Cron Jobs feature.
