Description

mod_userdir in lighttpd before 1.4.20, when a case-insensitive operating system or filesystem is used, performs case-sensitive comparisons on filename components in configuration options, which might allow remote attackers to bypass intended access restrictions, as demonstrated by a request for a .PHP file when there is a configuration rule for .php files.

Affected products

Debian Linux: 4.0
lighttpd: before 1.4.20 — fixed in 1.4.20

How to fix

Upgrade to a fixed version: lighttpd 1.4.20. Check the vendor advisory for mitigations.
