lighttpd < 1.4.20 Multiple Vulnerabilities
high Nessus Plugin ID 34332

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 1.4.20. It is, therefore, affected by multiple vulnerabilities :- A denial of service vulnerability exists in the connection_state_machine() function that is triggered when disconnecting before a download has finished. An unauthenticated, remote attacker can exploit this to cause all active SSL connections to be lost.
(CVE-2008-1531)
- A memory leak flaw exists in the http_request_parse() function. An unauthenticated, remote attacker can exploit this, via a large number of requests with duplicate request headers, to cause a denial of service condition. (CVE-2008-4298)
- A security bypass vulnerability exists due to comparing URIs to patterns in url.redirect and url.rewrite configuration settings before performing URL decoding.
An unauthenticated, remote attacker can exploit this to bypass intended access restrictions, resulting in the disclosure or modification of sensitive data.
(CVE-2008-4359)
- A security bypass vulnerability exists in mod_userdir due to performing case-sensitive comparisons even on case-insensitive operating systems and file systems. An unauthenticated, remote attacker can exploit this to bypass intended access restrictions, resulting in the disclosure of sensitive information. (CVE-2008-4360)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
