The vulnerability exists because the affected software does not restrict the maximum size of certain files that can be written to disk. An attacker who has valid administrator credentials for an affected system could exploit this vulnerability by sending a crafted, remote connection request to an affected system. A successful exploit could allow the attacker to write a file that consumes most of the available disk space on the system, causing application functions to operate abnormally and leading to a DoS condition.","state":"PUBLIC","assigner":"psirt@cisco.com","published_at":"2018-10-05 14:29:00","updated_at":"2019-10-09 23:35:00"},"problem_types":["CWE-400"],"metrics":[],"references":[{"url":"http://www.securitytracker.com/id/1041782","name":"1041782","refsource":"SECTRACK","tags":["Third Party Advisory","VDB Entry"],"title":"Cisco Unity Connection Bulk Administration Tool Validation Flaw Lets Remote Authenticated Users Consume Excessive Memory Resources - SecurityTracker","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-unity-dos","name":"20181003 Cisco Unity Connection File Upload Denial of Service Vulnerability","refsource":"CISCO","tags":["Vendor Advisory"],"title":"Cisco Unity Connection File Upload Denial of Service Vulnerability","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2018-15396","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-15396","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2018","cve_id":"15396","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"unity_connection","cpe6":"12.5","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2018","cve_id":"15396","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"unity_connection","cpe6":"12.5","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":"2018-10-03T16:00:00-0500","ID":"CVE-2018-15396","STATE":"PUBLIC","TITLE":"Cisco Unity Connection File Upload Denial of Service Vulnerability"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"Cisco Unity Connection ","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"Cisco"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"A vulnerability in the Bulk Administration Tool (BAT) for Cisco Unity Connection could allow an authenticated, remote attacker to cause high disk utilization, resulting in a denial of service (DoS) condition.
