        "text": "Update from October 22nd, 2020: Cisco has become aware of a new Cisco Adaptive Security Appliance vulnerability that could affect the fixed releases recommended for code trains 9.13 and 9.14 in the Fixed Software [\"#fs\"] section of this advisory. See the Cisco Adaptive Security Appliance Software SSL/TLS Denial of Service Vulnerability [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-ssl-dos-7uZWwSEy\"] for additional information.\r\n\r\nA vulnerability in the web-based management interface of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.\r\n\r\nThis vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\n",

See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.\r\n  Determine the Device Configuration\r\nTo determine whether web management is enabled, use the show running-config http command. The following example shows the output of the command for a device that has the web management feature enabled and that allows access to the web management feature from the 10.10.10.0/24 network through the management interface:\r\n\r\n\r\nciscoasa# show running-config http\r\n  http server enable  http 10.10.10.0 255.255.255.0 Management\r\n\r\nNote: The device would only be vulnerable to requests that are sent from an IP address in the range that is configured in the http \u003cremote_ip_address\u003e \u003cremote_subnet_mask\u003e \u003cinterface_name\u003e command.",
