Cybersecurity researchers on Tuesday disclosed aspects about a significant-severity flaw in the HP OMEN driver software that impacts tens of millions of gaming computers around the globe, leaving them open up to an array of attacks.
Tracked as CVE-2021-3437 (CVSS score: 7.8), the vulnerabilities could make it possible for risk actors to escalate privileges to kernel method devoid of requiring administrator permissions, letting them to disable security products, overwrite procedure elements, and even corrupt the working method.
Cybersecurity organization SentinelOne, which found and claimed the shortcoming to HP on February 17, claimed it located no evidence of in-the-wild exploitation. The pc hardware enterprise has because released a security update to its consumers to deal with these vulnerabilities.
The issues by themselves are rooted in a part referred to as OMEN Command Center that comes pre-installed on HP OMEN-branded laptops and desktops and can also be downloaded from the Microsoft Store. The software, in addition to checking the GPU, CPU, and RAM through a vitals dashboard, is designed to assist fantastic-tune network website traffic and overclock the gaming Computer system for more rapidly computer system efficiency.
“The problem is that HP OMEN Command Heart contains a driver that, even though ostensibly formulated by HP, is truly a partial copy of an additional driver complete of recognised vulnerabilities,” SentinelOne scientists said in a report shared with The Hacker Information.
“In the ideal instances, an attacker with entry to an organization’s network may also acquire access to execute code on unpatched methods and use these vulnerabilities to get neighborhood elevation of privileges. Attackers can then leverage other procedures to pivot to the broader network, like lateral movement.”
The driver in problem is HpPortIox64.sys, which derives its performance from OpenLibSys-made WinRing0.sys — a problematic driver that emerged as the resource of a nearby privilege escalation bug in EVGA Precision X1 application (CVE-2020-14979, CVSS score: 7.8) very last 12 months.
“WinRing0 allows buyers to examine and publish to arbitrary physical memory, read through and modify the model-unique registers (MSRs), and study/create to IO ports on the host,” scientists from SpecterOps pointed out in August 2020. “These characteristics are supposed by the driver’s builders. On the other hand, simply because a very low-privileged user can make these requests, they existing an chance for nearby privilege escalation.”
The core issue stems from the actuality that the driver accepts input/output command (IOCTL) calls without applying any form of ACL enforcement, thus allowing terrible actors unrestricted access to the aforementioned options, like capabilities to overwrite a binary that is loaded by a privileged approach and in the end operate code with elevated privileges.
“To lessen the attack area delivered by gadget drivers with uncovered IOCTLs handlers, developers ought to enforce strong ACLs on system objects, verify user enter and not expose a generic interface to kernel method operations,” the researchers claimed.
The results mark the second time WinRing0.sys has arrive beneath the lens for causing security issues in HP merchandise.
In Oct 2019, SafeBreach Labs exposed a critical vulnerability in HP Touchpoint Analytics software package (CVE-2019-6333), which comes incorporated with the driver, therefore potentially enabling menace actors to leverage the element to read through arbitrary kernel memory and correctly allowlist destructive payloads by way of a signature validation bypass.
Next the disclosure, organization firmware security enterprise Eclypsium — as portion of its “Screwed Drivers” initiative to compile a repository of insecure motorists and get rid of light on how they can be abused by attackers to obtain manage around Windows-based mostly units — dubbed WinRing0.sys a “wormhole driver by style and design.”
The discovery is also the third in a collection of security vulnerabilities influencing software program drivers that have been uncovered by SentinelOne since the begin of the calendar year.
Earlier this Could, the Mountain See-based organization exposed facts about several privilege escalation vulnerabilities in Dell’s firmware update driver named “dbutil_2_3.sys” that went undisclosed for additional than 12 a long time. Then in July, it also manufactured community a higher-severity buffer overflow flaw impacting “ssport.sys” and employed in HP, Xerox, and Samsung printers that was discovered to have remained undetected given that 2005.
