  Severity: Low
     Title: lighttpd: Script source disclosure
      Date: February 15, 2005
      Bugs: #81776
        ID: 200502-21

Synopsis
=======
An attacker can trick lighttpd into revealing the source of scripts
that should be executed as CGI or FastCGI applications.

Background
=========
lighttpd is a small-footprint, fast, compliant and very flexible
web-server which is optimized for high-performance environments.

Affected packages
================
    -------------------------------------------------------------------
     Package               /   Vulnerable   /               Unaffected
    -------------------------------------------------------------------
  1  www-servers/lighttpd      < 1.3.10-r1                >= 1.3.10-r1

Description
==========
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.

Resolution
=========
All lighttpd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.3.10-r1"
