Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Primary sources: NVD · CVE.org

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.
