Usermin 0.980 through 1.x before 1.660 allows uconfig_save.cgi sig_file_free remote code execution because it uses the two argument (not three argument) form of Perl open.
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.
Multiple stored cross-site scripting (XSS) vulnerabilities in Usermin 2.000 allow remote attackers to inject arbitrary web script or HTML via the folder name parameter while creating the folder to manage the folder tab, filter tab, and forward mail tab.
A reflected cross-site scripting (XSS) vulnerability in the File Manager function of Webmin v2.100 allows attackers to execute malicious scripts via injecting a crafted payload into the Find in Results file.
A stored cross-site scripting (XSS) vulnerability in Webmin v2.100 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the cloned module name parameter.
A reflected cross-site scripting (XSS) vulnerability in the File Manager function of Webmin v2.100 allows attackers to execute malicious scripts via injecting a crafted payload into the Replace in Results file.
An issue was discovered in Webmin 2.100. The File Manager functionality allows an attacker to exploit a Cross-Site Scripting (XSS) vulnerability. By providing a malicious payload, an attacker can inject arbitrary code, which is then executed within the context of the victim's browser when any file is searched/replaced.
