The vulnerability is due to the use of an incorrect data type for a length variable. An attacker could exploit this vulnerability by initiating the transfer of a large file to an affected device via SCP. To exploit this vulnerability, the attacker would need to have valid privilege level 15 credentials on the affected device. A successful exploit could allow the attacker to cause the length variable to roll over, which could cause the affected device to crash.","severity":{"version":"3.0","score":6.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.01488,"percentile":0.74239,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-190","CWE-704"],"published":"2019-10-02T19:06:46Z","modified":"2026-06-17T02:15:14Z","products":[{"vendor":"cisco","product":"adaptive_security_appliance"},{"vendor":"cisco","product":"adaptive_security_appliance_software"},{"vendor":"cisco","product":"cisco adaptive security appliance (asa) software"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-scp-dos","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2019-12693"},{"url":"https://github.com/advisories/GHSA-rc7c-qrr9-4694"}],"sources":{"cve":[{"id":"CVE-2019-12693","title":"Cisco Adaptive Security Appliance Software Secure Copy Denial of Service Vulnerability","description":"A vulnerability in the Secure Copy (SCP) feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition.
