https://notcve.org/view.php?id=CVE-2024-33897
06 Aug 2024 — A compromised HMS Networks Cosy+ device could be used to request a Certificate Signing Request from Talk2m for another device, resulting in an availability issue. The issue was patched on the Talk2m production server on April 18, 2024. During account assignment in the Talk2M platform, a Cosy+ device generates and sends a certificate signing request (CSR) to the back end. This CSR is then signed by the manufacturer and used for OpenVPN authentication by the device afterward. Since the common name (CN) of the... • https://packetstorm.news/files/id/180237 • CWE-425: Direct Request ('Forced Browsing') •

02 Aug 2024 — Insecure Permission vulnerability in Cosy+ devices running a firmware 21.x below 21.2s10 or a firmware 22.x below 22.1s3 are executing several processes with elevated privileges. The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. The Ewon Cosy+ executes all tasks and services in the context of the user "root" and therefore with the highest system privileges. By compromising a single service, attackers automatically gain full system access. • https://hmsnetworks.blob.core.windows.net/nlw/docs/default-source/products/cybersecurity/security-advisory/hms-security-advisory-2024-07-29-001--ewon-several-cosy--vulnerabilities.pdf • CWE-269: Improper Privilege Management •

02 Aug 2024 — Cosy+ devices running a firmware 21.x below 21.2s10 or a firmware 22.x below 22.1s3 use a unique key to encrypt the configuration parameters. This is fixed in version 21.2s10 and 22.1s3, the key is now unique per device. The Ewon Cosy+ is a VPN gateway used for remote access and maintenance in industrial environments. Due to the use of a hardcoded cryptographic key, an attacker is able to decrypt encrypted data and retrieve sensitive information. • https://packetstorm.news/files/id/180233 •
