{"vuid":"VU#621566","idnumber":"621566","name":"Linksys RT31P2 VoIP router denial of service vulnerabilities","keywords":["Linksys","routers","DoS","denial of service","VOIP","RT31P2"],"overview":"The Linksys RT31P2 VoIP router contains several vulnerabilities that may allow a remote, unauthenticated attacker to cause a denial of service.","clean_desc":"The Linksys RT31P2 is a broadband router that includes Voice over Internet Protocol (VoIP) telephone functionality. The RT31P2 unit fails to properly handle malformed Session Initiation Protocol (SIP) messages, which are used by VoIP.","impact":"A remote, unauthenticated attacker may be able to cause a denial-of-service condition. For example, when the phone is being used (off-hook), an attacker may be able to disrupt the call. When the phone is not being used (on-hook), an attacker may be able to cause the phone to stop working.","resolution":"We are currently unaware of a practical solution to this problem. The RT31P2 has been discontinued by Linksys.","workarounds":"","sysaffected":"","thanks":"Thanks to  Peter Thermos and Guy Hadsall of \nPalindrome Technologies\n for reporting this vulnerability.","author":"This document was written by Will Dormann.","public":["http://www1.linksys.com/products/product.asp?grid=34&prid=652","http://www.ietf.org/html.charters/sip-charter.html"],"cveids":[""],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2005-08-04T17:19:40Z","publicdate":"2006-04-19T00:00:00Z","datefirstpublished":"2006-04-19T20:46:22Z","dateupdated":"2006-05-05T00:49:45Z","revision":11,"vrda_d1_directreport":"1","vrda_d1_population":"2","vrda_d1_impact":"2","cam_widelyknown":"1","cam_exploitation":"0","cam_internetinfrastructure":"17","cam_population":"5","cam_impact":"3","cam_easeofexploitation":"14","cam_attackeraccessrequired":"19","cam_scorecurrent":"1.346625","cam_scorecurrentwidelyknown":"2.7680625","cam_scorecurrentwidelyknownexploited":"4.2643125","ipprotocol":"","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":1.346625,"vulnote":null}
