Folks - it’s time to tick everyone off with network maintenance windows! Cisco PSIRT released 30 vulnerabilities in their router firmware across multiple versions of IOS and IOS EX. Three critical vulnerabilities include one hard-coded credential affecting all IOS XE routers running IOS XE v16, and two which affect v15 under certain conditions. Fifteen high risk vulnerabilities run the gamut from denial of service, buffer overflow, and privileged escalation.
A complete list follows, and I will update it as more come in today.
