Command Lookup Tool For Cisco Software Checker

Use the Cisco IOS Software Checker to search for Cisco Security Advisories that apply to specific Cisco IOS and IOS XE Software releases.
To use the tool, choose one or more releases from the drop-down list, enter the output of the show version command, or upload a text file that lists specific releases, then choose whether to check against all or certain advisories and whether to include lower-impacting vulnerabilities. Only Critical and High rated vulnerabilities are included by default. The availability of security fixes after the End of Sale is defined in the product's End of Sale bulletin, as explained in the Cisco End-of-Life Policy. Additional information about Cisco software updates, vulnerability rating and scoring is available in the Cisco Security Vulnerability Policy. To see a brief tutorial for this tool, watch the video on this page.
The Cisco IOS Software Checker does not provide information about Cisco IOS XR Software releases or interim builds of Cisco IOS Software.
