CVE-2026-109445

PLANET GS-5220-8P2T2S Stack Buffer Overflow via webstax_auth Cookie

PLANET GS-5220-8P2T2S (hardware version 3.0) firmware versions before 3.2412b261008 contains a stack-based buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by submitting an oversized webstax_auth HTTP Cookie value that is copied into a fixed-size stack buffer without length validation. Attackers can send a crafted unauthenticated HTTP request with an oversized cookie to overwrite the saved return address and corrupt stack memory, leading to memory corruption and potential denial of service on the device.

CVE-2026-124002

Dixell/Copeland XWEB EVO Pre-Auth OS Command Injection via Username

XWEB EVO versions 5.2.3 through before 5.7.0 contains a pre-authentication OS command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary OS commands by injecting shell metacharacters into the username field of login.lua, cleanout.lua, or api.lua before the password check occurs. Attackers can exploit this flaw combined with the setuid-root wlua interpreter to execute commands with root privileges, achieving full system compromise. This product line reached it's end of service date in March 2026.

Dixell/Copeland XWEB EVO Unauthenticated Configuration Write via config.lua

XWEB EVO 4.3.0 through 5.8.8 contains an unauthenticated arbitrary file write vulnerability that allows remote attackers to modify the system configuration file /etc/xwebconfig.json by sending a crafted POST request to config.lua with action=set, which performs no session validation and writes the raw, unvalidated request body. Attackers can tamper with configuration values such as model and plugin fields or trigger a SYSTEM_NOT_CONFIGURED state via the unauthenticated action=get and action=set operations, resulting in configuration tampering and denial of service. This product line reached it's end of service date in March 2026.

Dixell/Copeland XWEB EVO Hardcoded Administrator Daily Password Authentication Bypass

XWEB EVO 5.6.2 through 5.8.8 contains a hardcoded credential vulnerability where the Administrator web account is configured to use password_mode daily_password with no stored password, as the Users.authenticate function in lualib_users.lua synthesizes the Administrator configuration without validating any stored secret. Attackers who can derive the MAC-based daily password can authenticate as Administrator to obtain a full admin session on the device.

XWEB EVO before 5.6.2 contains a command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary commands as root by exploiting the setuid-root CGI xwconsole.cgi. Attackers can supply malicious input through the sh parameter, which is passed unsanitized to popen(), to achieve full system compromise.

Dixell/Copeland XWEB EVO Pre-Auth OS Command Injection via Password Field

XWEB EVO before 5.6.2 contains a pre-authentication OS command injection vulnerability that allows unauthenticated remote attackers to execute arbitrary commands by injecting shell metacharacters into the password field. Attackers can exploit the unescaped interpolation of the password value into the hashpass invocation within login.lua, cleanout.lua, and api.lua to achieve root-level command execution via the setuid wlua interpreter.

Dixell/Copeland XWEB EVO Predictable Root Password Generation

XWEB EVO through 5.8.8 contains a predictable credential generation vulnerability that allows attackers to derive the Linux root password by computing a fixed prefix combined with a daily password value. Attackers can calculate the deterministic root credential, which before 5.7.0 was identical across all units and from 5.7.0 onward remains derivable from the MAC-based daily password, to gain unauthorized root access to the underlying operating system. This product line reached it's end of service date in March 2026.

Dixell/Copeland XWEB EVO Predictable Administrator Password Generation

XWEB EVO 4.3.0 through 5.8.8 contains a weak password generation vulnerability that allows remote attackers to derive the Administrator code-of-the-day password using only the device MAC address and date, with no server secret involved. Attackers can analyze the firmware binary xwpasswd, which itself functions as the password generator, to compute valid Administrator credentials offline and authenticate to the device without authorization.
