NVD Description

Note: Versions mentioned in the description apply only to the upstream lighttpd package and not the lighttpd package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An issue was discovered in mod_alias_physical_handler in mod_alias.c in lighttpd before 1.4.50. There is potential ../ path traversal of a single directory above an alias target, with a specific mod_alias configuration where the matched alias lacks a trailing '/' character, but the alias target filesystem path does have a trailing '/' character.
