This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code.","clean_desc":"Trend Micro ServerProtect is an anti-virus application that is designed to run on Microsoft Windows servers. Trend Micro ServerProtect handles Remote Procedure Calls (RPC) using port 5168/tcp. Trend Micro ServerProtect contains heap-based and stack-based buffer overflows in that can be exploited via multiple RPC functions. A remote, unauthenticated attacker may be able to trigger these overflows by sending malformed RPC requests to a vulnerable Trend Micro ServerProtect installation. More information, including a list of vulnerable RPC functions can be found in the README file for Security Patch 4.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary code with SYSTEM privileges.","resolution":"Apply a patch\nTrend Micro has addressed these vulnerabilities with Security Patch 4.","workarounds":"Restrict Access to Trend Micro ServerProtect Until the patch can be applied you may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by theTrend Micro ServerProtect  service (5168/tcp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate.","sysaffected":"","thanks":"This vulnerabilities were reported by iDefense Labs. iDefense Labs in turn credits Code Audit Labs, Jun Mao from iDefense Labs, and two anonymous researchers.","author":"This document was written by Jeff Gennari.","public":["http://www.trendmicro.com/ftp/documentation/readme/spnt_558_win_en_securitypatch4_readme.txt","http://www.trendmicro.com/download/product.asp?productid=17","http://labs.idefense.com/intelligence/vulnerabilities/display.php?id=587","http://secunia.com/advisories/26523/","http://us.trendmicro.com/us/products/enterprise/serverprotect-for-microsoft-windows/index.html","http://www.zerodayinitiative.com/advisories/ZDI-07-050.html"],"cveids":["CVE-2007-4218"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-08-22T14:20:41Z","publicdate":"2007-08-21T00:00:00Z","datefirstpublished":"2007-08-23T16:25:00Z","dateupdated":"2007-09-10T20:17:28Z","revision":23,"vrda_d1_directreport":"0","vrda_d1_population":"2","vrda_d1_impact":"3","cam_widelyknown":"8","cam_exploitation":"10","cam_internetinfrastructure":"7","cam_population":"10","cam_impact":"20","cam_easeofexploitation":"14","cam_attackeraccessrequired":"17","cam_scorecurrent":"22.3125","cam_scorecurrentwidelyknown":"33.0225","cam_scorecurrentwidelyknownexploited":"41.9475","ipprotocol":"tcp","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":22.3125,"vulnote":null}
