Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2024-28142

Medium
4.7/10

Summary

Due to missing input sanitization, an attacker can perform cross-site-scripting attacks and run arbitrary Javascript in the browser of other users. The "File Name" page (/cgi/uset.cgi?-cfilename) in the User Settings menu improperly filters the "file name" and wildcard character input field. By exploiting the wildcard character feature, attackers are able to store arbitrary Javascript code which is being triggered if the page is viewed afterwards, e.g. by higher privileged users such as admins. This attack can even be performed without being logged in because the affected functions are not fully protected. Without logging in, only the file name parameter of the "Default" User can be changed.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
