The remote web server may be affected by multiple vulnerabilities.
According to its banner, the version of Apache 2.2 installed on the
remote host is earlier than 2.2.22. It is, therefore, potentially
affected by the following vulnerabilities:
- When configured as a reverse proxy, improper use of the
RewriteRule and ProxyPassMatch directives could cause
the web server to proxy requests to arbitrary hosts.
This could allow a remote attacker to indirectly send
requests to intranet servers.
- A heap-based buffer overflow exists when mod_setenvif
module is enabled and both a maliciously crafted
'SetEnvIf' directive and a maliciously crafted HTTP
request header are used. (CVE-2011-3607)
- A format string handling error can allow the server to
be crashed via maliciously crafted cookies.
- An error exists in 'scoreboard.c' that can allow local
attackers to crash the server during shutdown.
- An error exists in 'protocol.c' that can allow
'HTTPOnly' cookies to be exposed to attackers through
the malicious use of either long or malformed HTTP
- An error in the mod_proxy_ajp module when used to
connect to a backend server that takes an overly long
time to respond could lead to a temporary denial of
Note that Nessus did not actually test for these flaws, but instead
has relied on the version in the server's banner.
