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.

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.

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.

This vulnerability allows remote attackers to escalate privileges on affected installations of Webmin. Authentication is required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8. The following CVEs are assigned: CVE-2025-2774.

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.

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.

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.

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 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 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 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. 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. 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 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, allowing an attacker to store a malicious payload in the Group Name field when creating a new group.

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.

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.

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.

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.

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 (XSS) vulnerability in Webmin 1.370 and 1.390 and Usermin 1.300 and 1.320 allows remote attackers to inject arbitrary web script or HTML via the search parameter to webminsearch.cgi (aka the search section), and possibly other components accessed through a "search box" or "open file box." NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in Webmin before 1.500 and Usermin before 1.430 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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."

Cross-site scripting (XSS) vulnerability in Webmin 1.540 and earlier allows local users to inject arbitrary web script or HTML via a chfn command that changes the real (aka Full Name) field, related to useradmin/index.cgi and useradmin/user-lib.pl.
