Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
A Stored Client Side Template Injection (CSTI) with Angular was discovered in the SolarWinds Orion Platform 2019.2 HF1 in many application forms. An attacker can inject an Angular expression and escape the Angular sandbox to achieve stored XSS. This can lead to privilege escalation.
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.
