NVIDIA was informed of this issue by Oden Schmit. You can download the fixes from the NVIDIA GeForce Experience Download page. Affected Products Affected Products Product NVIDIA doesn't know of any exploits to these issues at this time. NVIDIA recommends consulting a local security or IT professional to evaluate the risk of your specific configuration. NVIDIA’s risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk of your local installation.

To apply the security update, NVIDIA GeForce Experience users have to either download the latest version from the GeForce Experience Downloads page or to launch the client to have it applied via the inbuilt automatic update mechanism.NVIDIA GeForce Experience contains a vulnerability in NVIDIA Web Helper.exe where a local web API endpoint, /VisualOPS/v.1.0./, lacks proper access control and parameter validation, allowing for information disclosure through a directory traversal attack.ĬVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N/E:F/RL:O/RC:R

The two software flaws impact Windows computers where a version of NVIDIA GeForce Experience prior to 3.19 is installed. The Improper Input Validation issue was reported by David Yesland of Rhino Security Labs, while the DLL hijacking vulnerability was reported by multiple researchers (i.e., Kushal Arvind Shah of Fortinet's FortiGuard Labs, Łukasz 'zaeek', Yasin Soliman, Marius Gabriel Mihai, and Stefan Kanthak.) All GeForce Experience versions prior to 3.19 impacted

The attacker requires local system access.Īccording to NVIDIA, the "risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk of your local installation. NVIDIA GeForce Experience installer software contains a vulnerability in which it incorrectly loads Windows system DLLs without validating the path or signature (also known as a binary planting or DLL preloading attack), leading to escalation of privileges through code execution. Such an attack may lead to code execution, denial of service or information disclosure. NVIDIA GeForce Experience contains a vulnerability in the Web Helper component, in which an attacker with local system access can craft input that may not be properly validated.

The software flaws tracked as CVE‑2019‑5678 (Improper Input Validation) and CVE‑2019‑5676 (DLL hijacking) fixed in the May 2019 security update are detailed below, together with full descriptions and the CVSS V3 base scores assigned by NVIDIA. This could allow them to render vulnerable machines unusable by triggering a denial of service state or to execute malicious commands on the compromised Windows systems. Taking advantage of the vulnerabilities, attackers can escalate their privileges to gain permissions beyond the ones they were initially granted by the system.
What is nvidia web helper drivers#
NVIDIA GFE is a companion app for GeForce GTX graphics cards which, according to NVIDIA, "keeps your drivers up to date, automatically optimizes your game settings, and gives you the easiest way to share your greatest gaming moments with friends." NVIDIA rated the security issues as high severity While the two vulnerabilities require the would-be attackers to have local user access and cannot be exploited remotely, they can still be abused by dropping malicious tools remotely systems running vulnerable NVIDIA GFE versions.
What is nvidia web helper Patch#
NVIDIA issued a security update for the Windows NVIDIA GeForce Experience (GFE) software to patch two vulnerabilities that could make it possible for potential local attackers to launch attacks that may lead to code execution, escalation of privileges, and denial-of-service (DoS).
