Firewall Follies: Palo Alto’s Packet Peek-a-Boo Problem
Discover how Palo Alto’s Deep Packet Inspection mechanism allows data exfiltration with ease. Think of it as a firewall with a penchant for letting data sneak through, like a bouncer who lets everyone with a fake ID into the club. It’s a security flaw that’s all about making your data feel free and easy.
Hot Take:
When it comes to cybersecurity, you might think you’re safe behind a firewall. But as this report on Palo Alto’s Deep Packet Inspection (DPI) vulnerabilities shows, sometimes it’s more like using a colander to keep water in a bucket. Secure your popcorn, because this plot twist involves packets slipping through the cracks like a stealthy cat!
Key Points:
- Palo Alto’s Deep Packet Inspection (DPI) mechanism has three vulnerabilities allowing data exfiltration.
- The vulnerabilities affect all tested versions of PanOS, including 10.2.8 and 11.2.0.
- Data can be exfiltrated via TCP ports 80 and 443, and UDP on any port.
- Palo Alto considers these behaviors “feature requests” rather than security vulnerabilities.
- Recommendations include avoiding DPI-based rules and specifying IP addresses in firewall rules.
