lighttpd mod_userdir information disclosure
| lighttpd-moduserdir-info-disclosure (45689) |  Low Risk |
Description:
lighttpd could allow a remote attacker to obtain sensitive information. If a case-insensitive operating system is used to generate a filename, mod_userdir performs a case-sensitive comparison on filename components. A remote attacker could exploit this vulnerability to bypass security restrictions and gain unauthorized access to specific resources and obtain sensitive information.

- CVE-2008-4360: 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.
