CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-0652 – Local Privilege Escalation in Cloudflare WARP Installer (Windows)
https://notcve.org/view.php?id=CVE-2023-0652
Due to a hardlink created in the ProgramData folder during the repair process of the software, the installer (MSI) of WARP Client for Windows (<= 2022.12.582.0) allowed a malicious attacker to forge the destination of the hardlink and escalate privileges, overwriting SYSTEM protected files. As Cloudflare WARP client for Windows (up to version 2022.5.309.0) allowed creation of mount points from its ProgramData folder, during installation of the WARP client, it was possible to escalate privileges and overwrite SYSTEM protected files. • https://developers.cloudflare.com/warp-client/get-started/windows https://github.com/cloudflare/advisories/security/advisories/GHSA-xmhj-9p83-xvw9 https://install.appcenter.ms/orgs/cloudflare/apps/1.1.1.1-windows-1/distribution_groups/release • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2023-1412 – Local Privilege Escalation Vulnerability in WARP's MSI Installer
https://notcve.org/view.php?id=CVE-2023-1412
An unprivileged (non-admin) user can exploit an Improper Access Control vulnerability in the Cloudflare WARP Client for Windows (<= 2022.12.582.0) to perform privileged operations with SYSTEM context by working with a combination of opportunistic locks (oplock) and symbolic links (which can both be created by an unprivileged user). After installing the Cloudflare WARP Client (admin privileges required), an MSI-Installer is placed under C:\Windows\Installer. The vulnerability lies in the repair function of this MSI. ImpactAn unprivileged (non-admin) user can exploit this vulnerability to perform privileged operations with SYSTEM context, including deleting arbitrary files and reading arbitrary file content. This can lead to a variety of attacks, including the manipulation of system files and privilege escalation. PatchesA new installer with a fix that addresses this vulnerability was released in version 2023.3.381.0. While the WARP Client itself is not vulnerable (only the installer), users are encouraged to upgrade to the latest version and delete any older installers present in their systems. • https://developers.cloudflare.com/warp-client/get-started/windows https://github.com/cloudflare/advisories/security/advisories/GHSA-hgxh-48m3-3gq7 https://install.appcenter.ms/orgs/cloudflare/apps/1.1.1.1-windows-1/distribution_groups/release • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
