The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical vulnerability in Cisco Catalyst SD-WAN Manager to its Known Exploited Vulnerabilities catalog, requiring federal agencies to remediate by October 3, 2026. The flaw allows remote attackers to bypass authentication and gain admin access, with no available workaround except upgrading to fixed releases and restricting network access.
This Wire brief sits within Fusion42's coverage of Security Infrastructure.
◆ ◆ The Wire takeaway
You must act fast to upgrade Cisco SD-WAN Manager or isolate vulnerable systems now, or risk exposure with no workaround available. Federal networks are mandated to comply immediately, and private organisations ignoring this leave themselves wide open to attack.
