August 5: Cisco Patches Critical SD-WAN and IOS XE Flaws
In tech and security
Cisco has issued a broad set of security updates for critical flaws in its Catalyst SD-WAN and IOS XE network software. The most severe issues carry scores of up to 9.9 out of 10, and Cisco says there are no workarounds. The company says it has not seen active exploitation, but affected organizations should treat the updates as a priority, particularly for internet-facing network infrastructure.
The advisory batch also fixes high-severity bugs that could allow attackers to crash IOS XE devices, expose credentials in logs, or gain root-level access through Cisco's Integrated Management Controller. Several attacks require authentication, but the unauthenticated device-crash flaw does not. In short, this is a patch-now release, not a ticket to leave aging in a queue.
