CVE-2023-37599Public exploitNetwork attack vector

Unauthenticated file disclosure via modules directory indexing

Published Jul 13, 2023 · Updated Nov 5, 2024

Directory listing in Issabel issabel-pbx 4.0.0-6 allows remote attackers to read sensitive files through the web modules directory. The web server leaves automatic indexing enabled for /modules and serves a generated file listing when no index document is present. No authentication or user interaction is required, and exposed source, configuration, and helper files reveal internal application logic.
