CVE-2026-25818 1 Hms-networks 2 Ewon Cosy, Ewon Flexy 2026-03-16 9.1 Critical
HMS Networks Ewon Flexy with firmware before 15.0s4, Cosy+ with firmware 22.xx before 22.1s6, and Cosy+ with firmware 23.xx before 23.0s3 have weak entropy for authentication cookies, allowing an attacker with a stolen session cookie to find the user password by brute-forcing an encryption parameter.
CVE-2026-25823 1 Hms-networks 2 Ewon Cosy, Ewon Flexy 2026-03-16 9.8 Critical
HMS Networks Ewon Flexy with firmware before 15.0s4, Cosy+ with firmware 22.xx before 22.1s6, and Cosy+ with firmware 23.xx before 23.0s3 have a stack buffer overflow that leads to a Denial of Service, which can also be exploited to achieve Unauthenticated Remote Code Execution.
CVE-2026-25817 1 Hms-networks 2 Ewon Cosy, Ewon Flexy 2026-03-16 8.8 High
HMS Networks Ewon Flexy with firmware before 15.0s4, Cosy+ with firmware 22.xx before 22.1s6, and Cosy+ with firmware 23.xx before 23.0s3 have improper neutralization of special elements used in an OS command allowing remote code execution by attackers with low privilege access on the gateway, provided the attacker has credentials.
CVE-2026-25819 1 Hms-networks 2 Ewon Cosy, Ewon Flexy 2026-03-16 7.5 High
HMS Networks Ewon Flexy with firmware before 15.0s4, Cosy+ with firmware 22.xx before 22.1s6, and Cosy+ with firmware 23.xx before 23.0s3 allows unauthenticated attackers to cause a Denial of Service by using a specially crafted HTTP request that leads to a reboot of the device, provided they have access to the device's GUI.
CVE-2020-16230 1 Hms-networks 4 Ewon Cosy, Ewon Cosy Firmware, Ewon Flexy and 1 more 2024-11-21 2.3 Low
All version of Ewon Flexy and Cosy prior to 14.1 use wildcards such as (*) under which domains can request resources. An attacker with local access and high privileges could inject scripts into the Cross-origin Resource Sharing (CORS) configuration that could abuse this vulnerability, allowing the attacker to retrieve limited confidential information through sniffing.
CVE-2020-10633 1 Hms-networks 4 Ewon Cosy, Ewon Cosy Firmware, Ewon Flexy and 1 more 2024-11-21 6.1 Medium
A non-persistent XSS (cross-site scripting) vulnerability exists in eWON Flexy and Cosy (all firmware versions prior to 14.1s0). An attacker could send a specially crafted URL to initiate a password change for the device. The target must introduce the credentials to the gateway before the attack can be successful.
