GLSA-200502-21 : lighttpd: Script source disclosure

medium Nessus Plugin ID 16472

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200502-21 (lighttpd: Script source disclosure)

lighttpd uses file extensions to determine which elements are programs that should be executed and which are static pages that should be sent as-is. By appending %00 to the filename, you can evade the extension detection mechanism while still accessing the file.
Impact :

A remote attacker could send specific queries and access the source of scripts that should have been executed as CGI or FastCGI applications.
Workaround :

There is no known workaround at this time.

Solution

All lighttpd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/lighttpd-1.3.10-r1'
