CVE-2020-22864
Cross-Site Scripting (XSS) vulnerability in froala-editor (npm)
What is CVE-2020-22864 About?
A Cross-Site Scripting (XSS) vulnerability exists in the Insert Video function of Froala WYSIWYG Editor. This allows attackers to inject and execute arbitrary web scripts or HTML in a user's browser in the context of the vulnerable website. Exploitation is relatively easy, requiring user interaction with malicious content.
Affected Software
Technical Details
The Froala WYSIWYG Editor, specifically within its 'Insert Video' function, lacks proper sanitization or encoding of user-supplied input. An attacker can embed malicious JavaScript code or HTML tags within the video URL or other fields in the 'Insert Video' dialog. When this content is subsequently rendered by a client's browser, the embedded scripts are executed. This could happen if the crafted content is saved to a database and later displayed to other users, or if it is directly reflected back in an error message or preview, leading to stored XSS or reflected XSS respectively. The script execution occurs within the context of the vulnerable website, allowing access to cookies, session tokens, and other sensitive information.
What is the Impact of CVE-2020-22864?
Successful exploitation may allow attackers to execute arbitrary scripts in the victim's browser, leading to session hijacking, defacement of the web page, redirection to malicious sites, or unauthorized data access.
What is the Exploitability of CVE-2020-22864?
Exploitation of this XSS vulnerability is generally straightforward once a vector is identified. It typically requires an attacker to provide malicious input to the 'Insert Video' function, which then needs to be viewed or processed by a victim. Authentication requirements depend on whether the 'Insert Video' function is accessible to unauthenticated users or only authenticated ones; if the latter, the attacker needs to be authenticated. Privilege requirements are low, as the vulnerability lies in input handling. This is fundamentally a remote attack. Special conditions include the vulnerability being triggered when content containing the malicious script is rendered in a web browser. Risk factors increasing exploitation likelihood include applications allowing untrusted users to create or edit content using the Froala editor, especially if input sanitization is insufficient.
