Reflected XSS in AIL Framework

Description

AIL Framework contained a reflected cross-site scripting vulnerability in the /tag/add_tags endpoint. When an error occurred while processing a tag operation, the application returned the error value directly as an HTML response using str(res[0]). If attacker-controlled input was included in the generated error message, a crafted request could cause arbitrary HTML or JavaScript to be reflected in the response without appropriate output encoding. An attacker could exploit the vulnerability by convincing an authenticated AIL Framework user to open a specially crafted link. Successful exploitation could allow JavaScript to execute in the victim’s browser within the security context of the AIL Framework application. Depending on the victim’s privileges and the application’s protections, the attacker could perform actions using the victim’s session, access information available to the victim, or modify data through authenticated application requests. The vulnerability requires user interaction because the authenticated victim must follow or open the crafted request. The attacker does not necessarily require an AIL Framework account, provided that the crafted request can be delivered to an already authenticated user.

Attack-Flow Graph

Executive Summary

This vulnerability is a reflected cross-site scripting (XSS) flaw in the AIL Framework. It occurs in the /tag/add_tags endpoint where error messages are returned without proper output encoding. If an attacker includes malicious input in a tag operation, the error response could reflect arbitrary HTML or JavaScript code. This allows attackers to execute scripts in a victim's browser when they open a specially crafted link.

Detection Guidance

Detecting this reflected XSS vulnerability requires monitoring HTTP responses for the /tag/add_tags endpoint. Check for error messages containing user-controlled input reflected without proper encoding. Inspect network traffic for requests to /tag/add_tags with unusual parameters or error responses.

Impact Analysis

An attacker could exploit this to run malicious scripts in your browser within the AIL Framework session. This could let them perform actions using your session, access your data, or modify information if you are logged in. The attack requires you to click a malicious link, so user interaction is necessary.

Mitigation Strategies

Apply input validation and output encoding to the /tag/add_tags endpoint. Ensure all error messages are properly escaped before being reflected in HTML responses. Update to the latest patched version of AIL Framework if available.
