Palo Alto Warns of Zero-Day Bug in Firewalls Using GlobalProtect Portal VPN

Palo Alto Warns of Zero-Day Bug in Firewalls Using GlobalProtect Portal VPN
November 10, 2021Ravie Lakshmanan
A new zero-day vulnerability has been disclosed in Palo Alto Networks GlobalProtect VPN that could be abused by an unauthenticated network-based attacker to execute arbitrary code on affected devices with root user privileges. Tracked as CVE-2021-3064 (CVSS score: 9.8), the security weakness impacts PAN-OS 8.1 versions earlier than PAN-OS 8.1.17. Massachusetts-based cybersecurity firm Randori has been credited with discovering and reporting the issue. "The vulnerability chain consists of a method for bypassing validations made by an external web server (HTTP smuggling) and a stack-based buffer overflow," Randori researchers  said . "Exploitation of the vulnerability chain has been proven and allows for remote code execution on both physical and virtual firewall products." However, in a troubling turn of events, the company said it used this exploit as part of its red team engagements for nearly 10 months before disclosing it to Palo Alto Networks in late Septem

At least nine entities across the technology, defense, healthcare, energy, and education industries were compromised by leveraging a  recently patched critical vulnerability  in Zoho's ManageEngine ADSelfService Plus self-service password management and single sign-on (SSO) solution. The spying campaign, which was observed starting September 22, 2021, involved the threat actor taking advantage of the flaw to gain initial access to targeted organizations, before moving laterally through the network to carry out post-exploitation activities by deploying malicious tools designed to harvest credentials and exfiltrate sensitive information via a backdoor. "The actor heavily relies on the Godzilla web shell, uploading several variations of the open-source web shell to the compromised server over the course of the operation," researchers from Palo Alto Networks' Unit 42 threat intelligence team  said  in a report. "Several other tools have novel characteristics or ha

Enterprises should expect to see more cyberattacks launched against them. The data that they now gather and store have made their infrastructures key targets for hackers. Customer data and intellectual property can be sold in the black market for profit, and sensitive information can also be used by hackers to extort them. Enterprises are now aggressively shifting their workloads to the cloud which, while it has many benefits, expands their defensive perimeter and exposes them to further risks as well. As such, organizations are now widely investing in various security solutions in order to comprehensively protect their networks. Gartner expects security spending to exceed $124 billion this year. Solutions such as firewalls and threat prevention tools have increasingly become essential for enterprises. Leading firewall provider Palo Alto Networks , for example, provides companies with various measures to protect their infrastructures. It's currently being used by tens
