Summary

AIL Framework contains a stored cross-site scripting vulnerability in the crawler domain view. Crawled URLs were embedded directly into the JavaScript onclick handler used to display a stored screenshot, without context-appropriate encoding.

An attacker who can cause a specially crafted URL to be recorded in the crawler history can inject JavaScript syntax into the stored URL value. The payload remains stored by AIL and is subsequently included in the domain view. When an authenticated analyst clicks the screenshot icon associated with the malicious URL, the injected JavaScript executes in the analyst’s browser within the security context of the AIL Framework application.

Successful exploitation could allow an attacker to access information available to the analyst’s session, modify displayed content, or perform application actions using the analyst’s privileges. Exploitation requires the victim to interact with the affected screenshot entry.

The vulnerability was corrected by serializing the crawled URL with Jinja’s tojson filter before inserting it into the JavaScript handler. This safely escapes characters that could otherwise terminate the JavaScript string and introduce executable code.
