An attacker could exploit this vulnerability by sending an email that contains a crafted attachment through an affected device. A successful exploit could allow the attacker to replace any file on the underlying file system. The attacker could then perform any of the following actions: add users with root privileges, modify the device configuration, execute arbitrary code, or cause a permanent denial of service (DoS) condition on the affected device.\r\n\r\nNote: Manual intervention is required to recover from the DoS condition.

Customers with service contracts that entitle them to regular software updates should obtain security fixes through their usual update channels.\r\n\r\nCustomers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.\r\n\r\nThe Cisco Support and Downloads page [\"https://www.cisco.com/c/en/us/support/index.html\"] on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool.\r\n\r\nWhen considering software upgrades [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes\"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.\r\n  Customers Without Service Contracts\r\nCustomers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.\r\n      Fixed Releases\r\nThe fix for this vulnerability is distributed through an updated version of the Content Scanner Tools package. Content Scanner Tools versions 23.3.0.4823 and later contain the fix for this vulnerability.\r\n\r\nThe updated version of Content Scanner Tools is included by default in Cisco AsyncOS for Cisco Secure Email Software releases 15.5.1-055 and later.\r\n  Update the Content Scanner Tools\r\nUpdating the Content Scanner Tools does not require a software upgrade or a product restart. Customers who configured an automated Content Scanner Tools update may not be required to perform any action to address this vulnerability.\r\n\r\nManual Update\r\n\r\nTo manually update the Content Scanner Tools, use the command CLI contentscannerupdate, as shown in the following example:\r\n\r\n\r\ncisco-esa\u003e contentscannerupdate\r\nRequesting check for new Content Scanner updates.\r\n\r\nFor instructions on how to verify the current version, see the Vulnerable Products [\"#vp\"] section of this advisory.\r\n\r\nAutomatic Update\r\n\r\nTo enable automatic updates, complete the following steps on the web management interface:\r\n\r\nChoose Security Services \u003e Service Updates.\r\nClick Edit Update Settings.\r\nClick the Automatic Updates check box.\r\nClick Submit.\r\nChoose Commit Changes on the top right of the page.\r\nConfirm the uncommitted changes by clicking on Commit Changes.\r\n\r\nFor customers who use Cisco Secure Email Cloud Gateway, no action is required. Cisco has taken actions to protect the infrastructure from this vulnerability, and a fixed version of Content Scanner Tools will be deployed as part of the standard upgrade processes for the environment.\r\n\r\nThe Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory.",
