An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root.\r\n\r\nCisco has released software updates that address this vulnerability.

Customers 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\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\nCustomers are advised to upgrade to an appropriate fixed software release as indicated in the following table:\r\n        Cisco AsyncOS for Secure Web Appliance Major Release  First Fixed Release          10.1 and earlier  10.1.5-037      10.5  11.7.2-011      11.5  11.7.2-011      11.7  11.7.2-011      11.8  11.8.2-009      12.0  12.0.2-004      12.5  12.5.1-011\r\nIn most cases, the software can be upgraded over the network by using the System Upgrade options in the web interface of the Secure Web Appliance. To upgrade a device by using the web interface, do the following:\r\n\r\nChoose System Administration \u003e System Upgrade.\r\nClick Upgrade Options.\r\nChoose Download and Install.\r\nChoose the release to upgrade to.\r\nIn the Upgrade Preparation area, choose the appropriate options.\r\nClick Proceed to begin the upgrade. A progress bar displays the status of the upgrade.\r\n\r\nAfter the upgrade is complete, the device reboots.",
