Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
A vulnerability in SAP NW EP (WPC) - versions 7.30, 7.31, 7.40, 7.50, which does not sufficiently validate user-controlled input, allows a remote attacker to conduct a Cross-Site (XSS) scripting attack. A successful exploit could allow the attacker to execute arbitrary script code which could lead to stealing or modifying of authentication information of the user, such as data relating to his or her current session.
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.
