Restricted-document disclosure via predictable cache filenames

Published Nov 30, 2023 · Updated Aug 2, 2024

Information disclosure in Henschen & Associates CaseLook before 2023-11-22 allows remote attackers to access restricted court documents. Requested documents are copied into a web-accessible cache under numeric filenames from 0 through 32,767; the counter advances over time and by eight per request. No authentication is required, and enumerating the small filename space reveals cached documents regardless of their access restrictions.
