The version of lighttpd running on the remote web server is potentially
affected by multiple vulnerabilities.
According to its self-reported version, the lighttpd install on the
remote host is a version prior to 1.4.34. It is, therefore, potentially
affected by the following security issues :
- When Server Name Indication (SNI) is enabled, a flaw
exists that could cause the application to use all
available SSL ciphers, including weak ciphers. Remote
attackers could potentially hijack sessions or obtain
sensitive information by sniffing the network.
Note only versions 1.4.24 to 1.4.33 are affected.
- A flaw exists in the clang static analyzer because it
fails to perform checks around setuid (1), setgid (2),
and setgroups (3) calls. This could allow a remote
attacker to gain elevated privileges. (CVE-2013-4559)
- A use-after-free error exists in the clang static
analyzer, when the FAM stat cache engine is enabled.
This could allow remote attackers to dereference
already freed memory and crash the program.
Note that Nessus has not tested for this issue but has instead relied
only on the version in the server's banner.
