Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple stored cross-site scripting vulnerabilities in TeamPass before 18.104.22.168 allow authenticated remote attackers to inject arbitrary web script or HTML via the URL value of an item or user log history. To exploit the vulnerability, the attacker must be first authenticated to the application. For the first one, the attacker has to simply inject XSS code within the URL field of a shared item. For the second one however, the attacker must prepare a payload within its profile, and then ask an administrator to modify its profile. From there, whenever the administrator accesses the log, it can be XSS'ed.
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.
