Executive Summary

CVE-2022-50967 is a reflected cross-site scripting (XSS) vulnerability found in uBidAuction version 2.0.1, specifically in the tickets/manage module.

The vulnerability arises because the parameters date_created, date_from, date_to, and created_at in the filter functionality are not properly sanitized.

This improper input sanitization allows remote attackers to craft GET requests containing malicious scripts that get executed in the browsers of victims when they access the affected functionality.

Detection Guidance

This vulnerability can be detected by monitoring for suspicious or crafted GET requests targeting the tickets/manage module, specifically those including the parameters date_created, date_from, date_to, and created_at with potentially malicious script content.

You can use network traffic inspection tools or web server logs to identify such requests.

• Use curl or wget to manually test the parameters with script payloads, for example: curl "http://yourserver/tickets/manage?date_created=<script>alert(1)</script>"
• Use grep or similar tools on web server logs to search for suspicious script tags in the relevant parameters.
• Employ web vulnerability scanners that support reflected XSS detection on the affected endpoints.

Mitigation Strategies

Immediate mitigation steps include implementing proper input sanitization and validation on the date_created, date_from, date_to, and created_at parameters in the tickets/manage module to prevent injection of malicious scripts.

Additionally, consider applying any available patches or updates from the vendor that address this vulnerability.

As a temporary measure, you can also employ web application firewalls (WAFs) to block requests containing suspicious script content in these parameters.
