The vulnerability is due to improper processing of SMS protocol data units (PDUs) that are encoded with a special character set. An attacker could exploit this vulnerability by sending a malicious SMS message to an affected device. A successful exploit could allow the attacker to cause the wireless WAN (WWAN) cellular interface module on an affected device to crash, resulting in a DoS condition that would require manual intervention to restore normal operating conditions.","state":"PUBLIC","assigner":"psirt@cisco.com","published_at":"2019-03-28 00:29:00","updated_at":"2020-10-08 20:58:00"},"problem_types":["NVD-CWE-Other"],"metrics":[],"references":[{"url":"http://www.securityfocus.com/bid/107599","name":"107599","refsource":"BID","tags":["Third Party Advisory","VDB Entry"],"title":"Cisco IOS and IOS XE Software CVE-2019-1747 Denial of Service Vulnerability","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190327-sms-dos","name":"20190327 Cisco IOS and IOS XE Software Short Message Service Denial of Service Vulnerability","refsource":"CISCO","tags":["Patch","Vendor Advisory"],"title":"Cisco IOS and IOS XE Software Short Message Service Denial of Service Vulnerability","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2019-1747","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-1747","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2019","cve_id":"1747","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"cisco","cpe5":"ios","cpe6":"15.8(3)m","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2019","cve_id":"1747","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"cisco","cpe5":"ios","cpe6":"15.8\\(3\\)m","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2019","cve_id":"1747","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"cisco","cpe5":"ios","cpe6":"15.8\\(3\\)m","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2019","cve_id":"1747","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"cisco","cpe5":"ios_xe","cpe6":"16.10.1","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2019","cve_id":"1747","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"cisco","cpe5":"ios_xe","cpe6":"16.10.1","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"psirt@cisco.com","DATE_PUBLIC":"2019-03-27T16:00:00-0700","ID":"CVE-2019-1747","STATE":"PUBLIC","TITLE":"Cisco IOS and IOS XE Software Short Message Service Denial of Service Vulnerability"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"Cisco IOS and IOS XE Software","version":{"version_data":[{"version_affected":"=","version_value":"16.10.1"}]}}]},"vendor_name":"Cisco"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"A vulnerability in the implementation of the Short Message Service (SMS) handling functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device.
