Cisco CVE Common Vulnerabilities and Exposures

Multiple Cisco Products Snort TCP Fast Open File Policy Bypass Vulnerability

While this workaround has been deployed and was proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.
Cisco FTD Software Release 6.7.0
For Cisco FTD Software Release 6.7.0, as a workaround when the Snort 3 configuration option is enabled, an administrator may enable built-in rule 129:2 in the intrusion policy and set the action to Drop instead of Alert.
Use the following steps to verify that the Snort 3 configuration option is enabled. For more details, see the Switching Between Snort 2 and Snort 3 section of the Cisco Firepower Threat Defense Configuration Guide for Firepower Device Manager, Version 6.7.

Log in to the Admin Portal for the FTD deployment.
Navigate to Policies  > Intrusion.
Look for the Snort Version line above the table. The current version is the first number in the complete version number. For example, 2.9.17-95 is a Snort 2 version.

Use the following steps to enable rule 129:2. For more details, see the Changing Intrusion Rule Actions (Snort 3) section of the Cisco Firepower Threat Defense Configuration Guide for Firepower Device Manager, Version 6.7.

Log in to the Admin Portal for the FTD deployment.
Navigate to Policies  > Intrusion.
Choose any system-provided policy, such as Balanced Security and Connectivity.
Search for rule 129:2.
Check the check box next to the rule to enable it.
Choose Drop from the Action drop-down list.
Add the intrusion policy to a rule in Access control policy.

Cisco CVE Common Vulnerabilities and Exposures

Cisco Unified Communications Manager IM & Presence Service SQL Injection Vulnerabilities

Cisco has released free software updates that address the vulnerabilities described in this advisory. 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:https://www.cisco.com/c/en/us/products/end-user-license-agreement.html
Additionally, 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.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In 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.
Customers Without Service Contracts
Customers 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
Customers 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.
