Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Mobile application "Testes de Codigo" v11.3 and prior allows stored XSS by injecting a payload in the "feedback" message field causing it to be stored in the remote database and leading to its execution on client devices when loading the "feedback list", either by accessing the website directly or using the mobile application.
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.
