我在工作中遇到了一些困惑。我和一些工程師相信,nessus(就我們所知,是一個端口掃描器)不會在乎我想從/usr/java/apache-tomcat-5.5.33中重命名服務器上的tomcat目錄到/ usr/java/apache-tomcat。Nessus是否依賴或使用目錄路徑來確定版本?
我想這樣做是爲了生活,我們被迫當客戶哭升級我們的服務器下一次更容易「漏洞!」。
如此反覆,如果我想使Tomcat服務器路徑通用,Nessus的不會在乎一個位。該產品(Nessus)將能夠嗅出產品版本就好。
這是正確的嗎?
謝謝你的幫助。

Apache Tomcat 5.5.x < 5.5.34 Multiple Vulnerabilities Category: Web Servers
Description:
According to its self-reported version number, the instance of Apache
Tomcat 5.5.x listening on the remote host is earlier than 5.5.34 and
is affected by multiple vulnerabilities:
- Several weaknesses were found in the HTTP Digest
authentication implementation. The issues are as
follows: replay attacks are possible, server nonces
are not checked, client nonce counts are not checked,
'quality of protection' (qop) values are not checked,
realm values are not checked and the server secret is
a hard-coded, known string. The effect of these issues
is that Digest authentication is no stronger than Basic
authentication. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)
- An error handling issue exists related to the
MemoryUserDatabase that allows user passwords to be
disclosed through log files. (CVE-2011-2204)
- An input validation error exists that allows a local
attacker to either bypass security or carry out denial
of service attacks when the APR or NIO connectors are
enabled. (CVE-2011-2526)
- A component that Apache Tomcat relies on called 'jsvc'
contains an error in that it does not drop capabilities
after starting and can allow access to sensitive files
owned by the super user. Note this vulnerability only
affects Linux operating systems and only when 'jsvc' is
compiled with libpcap and the '-user' parameter is
used. (CVE-2011-2729)
- Specially crafted requests are incorrectly processed by
Tomcat and can cause the server to allow injection of
arbitrary AJP messages. This can lead to authentication
bypass and disclosure of sensitive information. Note
this vulnerability only occurs when the
org.apache.jk.server.JkCoyoteHandler AJP connector is
not used, POST requests are accepted, and the request
body is not processed.(CVE-2011-3190)
Note that Nessus did not actually test for the flaws but instead has
relied on the version in Tomcat's banner or error page.

你在做一個資格的掃描?否則,移動目錄的位置並不重要。 – rutgersmike 2012-03-27 14:34:58
感謝您的回覆。我添加了客戶給我們的報告樣本。 – 2012-03-27 14:48:43
但是要回答你的問題,我不知道。你會解釋什麼是憑證掃描?謝謝。 – 2012-03-27 14:55:08
