NVIDIA gaming graphics software called GeForce Experience, bundled with the chipmaker’s popular GTX GPU, is flawed and opens the door to a remote attacker that can exploit the bug to steal or manipulate data on a vulnerable Windows computer.

NVIDIA notified customers late last week of the bug and released a software patch for the flaw, which is present in its GeForce Experience (versions 3.21 and prior) Windows software. A 3.23 GeForce update is available now to mitigate the bug.

The bug is tracked as CVE‑2021‑1073, with a CVSS severity rating of 8.3 (high). The company warned: “NVIDIA GeForce Experience software contains a vulnerability where, if a user clicks on a maliciously formatted link that opens the GeForce Experience login page in a new browser tab instead of the GeForce Experience application and enters their login information, the malicious site can get access to the token of the user login session. Such an attack may lead to these targeted users’ data being accessed, altered, or lost.”

Who is Vulnerable to the NVIDIA Spoofing-Attack Bug?​

The prerequisites for an attack, known as a spoofing attack, include an adversary with network or remote access to the vulnerable PC. According NVIDIA details, because the victim must be coaxed into clicking on a malicious link, the attack is considered complex, reducing the risk of a successful exploitation.

The spoofing attack vulnerability is tied to incorrect processing of “special formatted links” in the NVIDIA GeForce Experience software. “A remote attacker can create a specially crafted link that opens the GeForce Experience login page in a new browser tab instead of the GeForce Experience application and enters their login information, the malicious site can get access to the token of the user login session,” according to a breakdown of the bug posted to Cybersecurity Help.

NVIDIA did not indicate if this vulnerability has been exploited. However, working exploits of the attack are not publicly available.
