“On devices with ASLR enabled (which appears to be the case in most hardware devices), exploitation is difficult but possible,” Randori researchers wrote. Randori said that the risk is particularly acute for virtual versions of the vulnerable product because it doesn’t have address space layout randomization-a security mechanism typically abbreviated as ASLR designed to greatly lessen the chances of successful exploitation-enabled. “And the sort of hole that the nastiest of actors have been exploiting in just about every remote access product over the last few years.” “A pretty gaping hole,” independent security researcher David Longenecker wrote of the GlobalProtect bug on Twitter. Request smuggling vulnerabilities are often critical because they allow an attacker to bypass security controls, gain unauthorized access to sensitive data, and directly compromise other application users. In the process, parts of a request may be appended to a later one that allows the response of the smuggled request to be provided to another user.

The confusion is usually the result of code libraries that deviate from specifications when dealing with both the Content-Length and the Transfer-Encoding header. The vulnerabilities arise when a website’s frontend and backend interpret the boundary of an HTTP request differently, and the error causes them to desynchronize. The buggy code can’t be accessed externally without utilizing what’s known as HTTP smuggling, an exploit technique that interferes with the way a website processes sequences of HTTP requests.

The overflow occurs when the software parses user-supplied input in a fixed-length location on the stack.

The portal also controls the behavior and distribution of the GlobalProtect app software to both macOS and Windows endpoints. Now, Palo Alto Networks’ GlobalProtect may be poised to join the list.Ī GlobalProtect portal provides management functions that lock down network endpoints and secures information about available gateways and any available certificates that may be required to connect to them. Similar enterprise products, including those from Pulse Secure and Sonic Wall, have also come under attack. Over the past few years, hackers have actively exploited vulnerabilities in a raft of enterprise firewalls and VPNs from the likes of Citrix, Microsoft, and Fortinet, government agencies warned earlier this year. “Once an attacker has control over the firewall, they will have visibility into the internal network and can proceed to move laterally.”
“Our team was able to gain a shell on the affected target, access sensitive configuration data, extract credentials, and more,” researchers from Randori wrote on Wednesday. A proof-of-concept exploit Randori researchers developed demonstrates the considerable damage that can result. Moving laterallyĬVE-2021-3064, as the vulnerability is tracked, is a buffer overflow flaw that occurs when parsing user-supplied input in a fixed-length location on the stack.
The norm among security professionals is for researchers to privately report high-severity vulnerabilities to vendors as soon as possible rather than hoarding them in secret. 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. 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.
