FreeBSD : lighttpd -- multiple vulnerabilities (fb911e31-8ceb-11dd-bb29-000c6e274733)
High Nessus Plugin ID 34310
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionLighttpd seurity announcement :
lighttpd 1.4.19, and possibly other versions before 1.5.0, does not decode the url before matching against rewrite and redirect patterns, which allows attackers to bypass rewrites rules. this can be a security problem in certain configurations if these rules are used to hide certain urls.
lighttpd 1.4.19, and possibly other versions before 1.5.0, does not lowercase the filename after generating it from the url in mod_userdir on case insensitive (file)systems.
As other modules are case sensitive, this may lead to information disclosure; for example if one configured php to handle files ending on '.php', an attacker will get the php source with http://example.com/~user/file.PHP
lighttpd 1.4.19 does not always release a header if it triggered a 400 (Bad Request) due to a duplicate header.
SolutionUpdate the affected package.
