lighttpd < 1.4.16 Multiple Vulnerabilities

high Nessus Plugin ID 106623

Synopsis

The remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of lighttpd running on the remote host is prior to 1.4.16. It is, therefore, affected by multiple vulnerabilities :

- mod_auth allows remote attackers to cause a denial of service via unspecified vectors involving (1) a memory leak, (2) use of md5-sess without a cnonce, (3) base64 encoded strings, and (4) trailing whitespace in the Auth-Digest header.
(CVE-2007-3946)

- The server allows remote attackers to cause a denial of service by sending an HTTP request with duplicate headers.
(CVE-2007-3947)

- The server might accept more connections than the configured maximum, which allows remote attackers to cause a denial of service via a large number of connection attempts.
(CVE-2007-3948)

- mod_access ignores trailing / (slash) characters in the URL, which allows remote attackers to bypass url.access-deny settings (CVE-2007-3949)

- The server, when run on 32 bit platforms, allows remote attackers to cause a denial of service (daemon crash) via unspecified vectors involving the use of incompatible format specifiers in certain debugging messages in the (1) mod_scgi, (2) mod_fastcgi, and (3) mod_webdav modules. (CVE-2007-3950)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to lighttpd version 1.4.16 or later.
