FortiSandbox Exploits Put Fortinet Appliances on a Patch Clock
Attackers are probing three critical FortiSandbox vulnerabilities that can expose Fortinet malware-analysis appliances to authentication bypass and command execution. Security teams should verify FortiSandbox 4.4 and 5.0 patch levels, check whether management interfaces are reachable, and review logs for exploit attempts rather than treating the April and June fixes as routine maintenance.
AryStinger Botnet Turns Old Routers Into Attack Proxies
Security researchers say AryStinger has compromised more than 4,300 legacy routers, turning aging home and small-office gear into proxy and reconnaissance infrastructure. The campaign is a reminder that end-of-life routers are not just slow or outdated; they can become someone else’s attack platform.
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.
F5’s Emergency NGINX Patches Put Web Server Teams on a Fast Upgrade Clock
F5 issued out-of-band NGINX updates for flaws affecting HTTP/3, proxy protocol, gRPC, Gateway Fabric, and related products. Teams running internet-facing NGINX should check versions, exposed modules, Kubernetes ingress paths, and temporary mitigations before treating this as routine patching.
HPE Turns Juniper Into the Network Layer for AI Factories
HPE used Discover 2026 to fold Juniper deeper into its AI data center strategy, adding QFX switches for inference and AMD Helios, Mist and Marvis AIOps updates, and SASE controls for self-driving networks.
