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. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment. 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. While this mitigation 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. Reloading the device will apply the correct programming to all ACLs and cause them to operate as configured, regardless of the method that was used for their initial configuration. However, there is no mechanism to determine whether an ACL has been correctly programmed on a device.
This vulnerability has not been found in ACLs that are manually configured using the CLI. However, administrators can reload the device to fix the ACL programming.
There are no workarounds that address this vulnerability. For a complete list of the advisories and links to them, see Cisco Event Response: September 2021 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication. This advisory is part of the September 2021 release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication. This advisory is available at the following link: A successful exploit could allow the attacker to bypass an ACL on the affected device.Ĭisco has released software updates that address this vulnerability.
An attacker could exploit this vulnerability by attempting to send traffic through an affected device. This vulnerability is due to incorrect programming of hardware when an ACL is configured using a method other than the configuration CLI.
