Technical description

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. This product line reached it's end of service date in March 2026.

———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.

—

———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. This product line reached it's end of service date in March 2026.3h CVE-2026-1240097.2 HIG

———XWEB EVO 5.2.3 through 5.8.8 contains an authenticated OS command injection vulnerability that allows authenticated attackers to execute arbitrary commands as root by injecting shell metacharacters into the output device path parameter processed by backup.lua. Attackers can exploit the unescaped concatenation into mount, unzip, and related shell commands run via the wlua interpreter, including through the setuid xwbackup.cgi and xwrestore.cgi interfaces, to achieve full system compromise.

———XWEB EVO 5.2.3 through 5.8.8 contains an authenticated OS command injection vulnerability in the devices.lua template handling, which allows authenticated attackers to execute arbitrary commands by injecting unescaped template source into unzip and related shell commands. Attackers can exploit this flaw through the wlua interpreter to execute arbitrary commands with root privileges on the affected device. This product line reached it's end of service date in March 2026.3h CVE-2026-1240029.8 CRI

———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.
