CVE-2018-0476 (GCVE-0-2018-0476)

Vulnerability from cvelistv5 – Published: 2018-10-05 14:00 – Updated: 2024-11-26 14:37
VLAI?
Summary
A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of SIP packets in transit while NAT is performed on an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SIP packets via UDP port 5060 through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
Severity ?

La vulnerabilidad se debe al procesamiento incorrecto de paquetes SIP en tr\u00e1nsito mientras se realiza NAT en un dispositivo afectado. Un atacante remoto no autenticado podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de paquetes SIP manipulados mediante el puerto UDP 5060 a trav\u00e9s de un dispositivo afectado que realiza NAT para los paquetes SIP. Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir que un atacante haga que el dispositivo afectado se reinicie, provocando una denegaci\u00f3n de servicio (DoS).\"}],\"metrics\":{\"cvssMetricV30\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.9,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.2,\"impactScore\":3.6}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:N/I:N/A:C\",\"baseScore\":7.1,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"COMPLETE\"},\"baseSeverity\":\"HIGH\",\"exploitabilityScore\":8.6,\"impactScore\":6.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-399\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:cisco:ios_xe:15.5\\\\(3\\\\)s5.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"049B7B21-7127-497A-AFB8-4FFB781B8C3A\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:cisco:ios_xe:15.5\\\\(3\\\\)s6.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"5469FA2A-6B82-451F-B970-2BF1F0B09BAB\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:cisco:ios_xe:16.6.2:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"E36D2D24-8F63-46DE-AC5F-8DE33332EBC6\"}]}]}],\"references\":[{\"url\":\"http://www.securityfocus.com/bid/105419\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"http://www.securitytracker.com/id/1041734\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"http://www.securitytracker.com/id/1041737\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-sip-alg\",\"source\":\"psirt@cisco.com\",\"tags\":[\"Vendor Advisory\"]},{\"url\":\"http://www.securityfocus.com/bid/105419\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"http://www.securitytracker.com/id/1041734\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"http://www.securitytracker.com/id/1041737\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Third Party Advisory\",\"VDB Entry\"]},{\"url\":\"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-sip-alg\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Vendor Advisory\"]}]}}",
