About 10,000 enterprise servers running Palo Alto Networks’ GlobalProtect VPN are vulnerable to a just-patched buffer overflow bug with a severity rating of 9.8 out of a possible 10.
Security firm Randori said on Wednesday that it discovered the vulnerability 12 months ago and for most of the time since has been privately using it in its red team products, which help customers test their network defenses against real-world threats.
