{"id":"CVE-2024-20359","kind":"vulnerability","aliases":["CVE-2024-20359"],"related":[],"title":"cisco adaptive security appliance software: A vulnerability in a legacy capability that allowed for the preloading of VPN clients and plug-ins and that has been…","description":"A vulnerability in a legacy capability that allowed for the preloading of VPN clients and plug-ins and that has been available in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to execute arbitrary code with root-level privileges. Administrator-level privileges are required to exploit this vulnerability.\r\n\r This vulnerability is due to improper validation of a file when it is read from system flash memory. An attacker could exploit this vulnerability by copying a crafted file to the disk0: file system of an affected device. A successful exploit could allow the attacker to execute arbitrary code on the affected device after the next reload of the device, which could alter system behavior. Because the injected code could persist across device reboots, Cisco has raised the Security Impact Rating (SIR) of this advisory from Medium to High.","summary":"Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) firewalls contain a flaw that lets a logged-in administrator escalate to root. An attacker who already holds administrator access on the device gets full control of the appliance.","severity":"high","cvss":6.0,"epss":null,"exploited":true,"exploited_at":"2024-04-24T00:00:00+00:00","products":[{"name":"Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD)","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.1","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.1.5","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.1.7","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.8","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.14","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.15","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.17","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.20","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.24","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.26","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.28","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.33","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.35","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.2.38","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.8","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.11","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.14","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.16","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.18","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.21","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.26","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.3.29","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.3","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.7","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.8","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.10","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.12","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.15","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.17","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.20","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.22","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.25","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.26","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.29","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.32","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.33","ecosystem":"vendor"},{"name":"cisco adaptive security appliance software","fixed":[],"affected":"= 9.8.4.34","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["asa","cisco","exploited","firewall","ftd","infrastructure","self-hosted"],"not_affected_if":["unknown"],"how_to_check":null,"fix":"Apply the mitigations in Cisco's vendor advisory per CISA's required action;
