CVE-ID: CVE-2021-41086

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via clipboard content. jsuites is vulnerable to DOM based XSS if the user can be tricked into copying _anything_ from a malicious and pasting it into the html editor. This is because a part of the clipboard content is directly written to `innerHTML` allowing for javascript injection and thus XSS. Users are advised to update to version 4.9.11 to resolve. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Install update from vendor's website.
