Descrição técnica

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.

———XWEB EVO 5.6.2 through 5.8.8 contains an authentication bypass vulnerability that allows unauthenticated attackers to set the password of any account flagged must-reset-at-next-login by exploiting missing session validation in the users.lua update_password action. Attackers can reset the password of newly onboarded operator accounts, clearing the password_expiration flag and gaining an immediately usable authenticated foothold on the system.

—

———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.

———XWEB EVO 5.6.2 through 5.8.8 contains an authenticated OS command injection vulnerability in the api.lua import_preconfiguration and restore actions, where server_url and related server credential fields are concatenated unescaped into a root curl command executed via io.popen. Attackers can inject malicious shell commands through these unfiltered parameters to achieve arbitrary command execution with root privileges on the underlying system.
