Reflected XSS via client-controlled JavaScript URL parameters
Published Jan 24, 2022 · Updated Aug 4, 2024
Reflected XSS in COINS Construction Cloud 11.12 allows remote attackers to execute JavaScript in a logged-in user's browser via a malicious URL. The postCheckRowids and afterPost HTTP GET parameters pass client-controlled JavaScript to downstream components, which execute substituted code when the page loads. Exploitation requires a logged-in user to visit the crafted link; the resulting script runs in that user's application context.
