VMware vSphere 6.7 EAM Tomcat STIG:
VCEM-67-000023
(in versions v1 r4 through v1 r1)
Title
ESX Agent Manager must not show directory listings. (Cat II impact)
Discussion
Enumeration techniques, such as URL parameter manipulation, rely on being able to obtain information about the web server's directory structure by locating directories without default pages. In this scenario, the web server will display to the user a listing of the files in the directory being accessed. Ensuring that directory listing is disabled is one approach to mitigating the vulnerability. In Tomcat, directory listing is disabled by default but can be enabled via the "listings" parameter. Ensure that this node is not present in order to have the default effect.
Check Content
At the command prompt, execute the following command: # xmllint --format /usr/lib/vmware-eam/web/webapps/eam/WEB-INF/web.xml | sed 's/xmlns=".*"//g' | xmllint --xpath '//param-name[text()="listings"]/parent::init-param' - Expected result: XPath set is empty If the output of the command does not match the expected result, this is a finding.
Fix Text
Navigate to and open: /usr/lib/vmware-eam/web/webapps/eam/WEB-INF/web.xml Find and remove the entire block returned in the check. Example: <init-param> <param-name>listings</param-name> <param-value>true</param-value> </init-param>
