{"id":"CVE-2021-1585","aliases":["EUVD-2021-7052","GHSA-3fc6-gf75-vvc3"],"status":"published","title":"Cisco Adaptive Security Device Manager Remote Code Execution Vulnerability","description":"A vulnerability in the Cisco Adaptive Security Device Manager (ASDM) Launcher could allow an unauthenticated, remote attacker to execute arbitrary code on a user's operating system. This vulnerability is due to a lack of proper signature verification for specific code exchanged between the ASDM and the Launcher. An attacker could exploit this vulnerability by leveraging a man-in-the-middle position on the network to intercept the traffic between the Launcher and the ASDM and then inject arbitrary code. A successful exploit could allow the attacker to execute arbitrary code on the user's operating system with the level of privileges assigned to the ASDM Launcher. A successful exploit may require the attacker to perform a social engineering attack to persuade the user to initiate communication from the Launcher to the ASDM.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.19958,"percentile":0.97454,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":true,"fix_available":false},"cwes":["CWE-94"],"published":"2021-07-08T18:35:27Z","modified":"2026-06-17T03:32:06Z","exploits":[{"source":"pocgithub","id":"jbaines-r7/staystaystay","title":"jbaines-r7/staystaystay","date":"2022-02-10","url":"https://github.com/jbaines-r7/staystaystay"}],"products":[{"vendor":"cisco","product":"adaptive_security_device_manager"},{"vendor":"cisco","product":"cisco adaptive security appliance (asa) software"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asdm-rce-gqjShXW","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://www.rapid7.com/blog/post/2022/08/11/rapid7-discovered-vulnerabilities-in-cisco-asa-asdm-and-firepower-services-software/","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory"]},{"url":"https://github.com/jbaines-r7/staystaystay","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-1585"},{"url":"https://github.com/advisories/GHSA-3fc6-gf75-vvc3"}],"sources":{"cve":[{"id":"CVE-2021-1585","title":"Cisco Adaptive Security Device Manager Remote Code Execution Vulnerability","description":"A vulnerability in the Cisco Adaptive Security Device Manager (ASDM) Launcher could allow an unauthenticated, remote attacker to execute arbitrary code on a user's operating system.
