NVD Description

Note: Versions mentioned in the description apply only to the upstream rmt-server-pubcloud package and not the rmt-server-pubcloud package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Directory interpolates the configured root path directly into a regular expression when deriving the displayed directory path. If root contains regex metacharacters such as +, *, or ., the prefix stripping can fail and the generated directory listing may expose the full filesystem path in the HTML output. This issue has been patched in versions 2.2.23, 3.1.21, and 3.2.6.
