PODoes Nessus depend or use directory paths for determining versions?

Body
copied!<p>I have a bit of confusion going on here at work. I and a handful of engineers believe that nessus (being a port scanner as far as we know) won't care one bit that I wish to rename the tomcat directory on our server from /usr/java/apache-tomcat-5.5.33 to /usr/java/apache-tomcat. </p> <p>I wish to do this to make life easier for the next time we are forced to upgrade our servers when a customer cries "Vulnerability!".</p> <p>So again, if I wish to make the tomcat server path generic, Nessus won't care one bit. That product (Nessus) will be able to sniff out the product version just fine. </p> <p>Is that correct?</p> <p>Thank you for the help.</p> <p>-dklotz</p> <p>-edit- Here is the scan reported to us by the customer.</p> <pre><code>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.
