The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning to public and federal IT security teams to implement available fixes because software that runs Palo Alto Networks firewalls is under attack.
Governmental organizations are urged to fix the bug by September 9. Palo Alto Networks released a patch earlier this month for the high-severity bug (CVE-2022-0028) that it claims adversaries tried to exploit. Without having to authenticate the targeted systems, remote hackers could use the flaw to launch reflected and amplified denial-of-service (DoS) attacks.
According to Palo Alto Networks, the vulnerability can only be used on a small number of systems, in specific circumstances, and that the vulnerable systems are not a common firewall configuration.
