CVE-2024-2550Network attack vector

Service interruption via crafted packet null dereference

Published Nov 14, 2024 · Updated Nov 14, 2024

Null pointer dereference in the PAN-OS GlobalProtect gateway allows remote attackers to stop its service with a crafted packet. Palo Alto Networks has not disclosed which packet field reaches the null pointer or the gateway code path that dereferences it. Only firewalls configured with a GlobalProtect gateway are exposed; repeated packets place the firewall in maintenance mode.
