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"
References ==========
