iDirect Satellite Terminal Flaws Put Link Management on the Patch List
CISA says ST Engineering iDirect iQ-Series satellite terminals running software 4.5.2.1 or earlier expose sensitive device identifiers and can be forced into reboots through weak API controls. Operators should treat the July 2 advisory as both a patch event and a management-plane exposure audit.
Cisco’s Twice-Monthly Patch Cadence Starts With Catalyst Center and ClamAV Fixes
Cisco’s first July security-advisory drop under its new twice-monthly cadence includes a Catalyst Center arbitrary-file-read flaw and seven ClamAV vulnerabilities affecting Cisco Secure Endpoint. The change gives network and security teams more predictability, but it also means Cisco infrastructure patch planning needs to become a standing operating rhythm, not a quarterly scramble.
Mandiant Details Cisco SD-WAN Attack That Turned a Malicious CSV Into Root Access
Mandiant says an attacker used rogue Cisco Catalyst SD-WAN peering, admin password manipulation, and CVE-2026-20245 to gain root access through a malicious CSV upload. The new details make the June SD-WAN advisories an incident-response problem, not just a patching task.
CISA Gives UniFi OS and Lantronix Flaws a June 26 Patch Deadline
CISA added three Ubiquiti UniFi OS flaws and a Lantronix EDS5000 code-injection bug to its Known Exploited Vulnerabilities catalog, setting a June 26 remediation deadline for federal agencies. The risk is not just another CVE list: exposed network management interfaces can become a fast path to device control.
CISA’s June 23 Deadline Puts Cisco SD-WAN, Chrome, and Arista EOS on the Triage List
CISA’s June 23 remediation deadline covers three actively exploited flaws across Cisco Catalyst SD-WAN Manager, Google Chrome’s V8 engine, and Arista EOS. The useful move for security teams is not treating them as one patch chore, but triaging each layer: network control plane, browsers, and tunnel decapsulation paths.
Cisco ISE Flaws Put Network Access Control on a Patch Clock
Cisco patched two Identity Services Engine flaws that can expose hashed credentials and let an authenticated attacker run commands on the underlying operating system. The urgency is highest for teams running ISE 3.4, ISE 3.5, or ISE-PIC, especially because one Cisco ISE 3.5 fix is not due in the normal patch stream until August.
