Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in Sonatype Nexus Repository Manager (aka NXRM) 3.x before 3.8 allow remote attackers to inject arbitrary web script or HTML via (1) the repoId or (2) format parameter to service/siesta/healthcheck/healthCheckFileDetail/.../index.html; (3) the filename in the "File Upload" functionality of the Staging Upload; (4) the username when creating a new user; or (5) the IQ Server URL field in the IQ Server Connection functionality.
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.
