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

CVE-2022-22115

High
9/10

Summary

In Teedy, versions v1.5 through v1.9 are vulnerable to Stored Cross-Site Scripting (XSS) in the name of a created Tag. Since the Tag name is not being sanitized properly in the edit tag page, a low privileged attacker can store malicious scripts in the name of the Tag. 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, and privileges 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.
