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

CVE-2019-9957

Medium
5.4/10

Summary

Stored XSS within Quadbase EspressReport ES (ERES) v7.0 update 7 allows remote attackers to execute malicious JavaScript and inject arbitrary source code into the target pages. The XSS payload is stored by creating a new user account, and setting the username to an XSS payload. The stored payload can then be triggered by accessing the "Set Security Levels" or "View User/Group Relationships" page. If the attacker does not currently have permission to create a new user, another vulnerability such as CSRF must be exploited first.

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.
