Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
In Teedy, versions v1.5 through v1.9 are vulnerable to Reflected Cross-Site Scripting (XSS). The “search term" search functionality is not sufficiently sanitized while displaying the results of the search, which can be leveraged to inject arbitrary scripts. These scripts are executed in a victim’s browser when they enter the crafted URL. In the worst case, the victim who inadvertently triggers the attack is a highly privileged administrator. The injected scripts can extract the Session ID, which can lead to full Account Takeover of the administrator, by an unauthenticated attacker.
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.
