nxapplet.jar in No Machine NX Web Companion 3.x and earlier does not properly verify the authenticity of updates, which allows user-assisted remote attackers to execute arbitrary code via a crafted (1) SiteUrl or (2) RedirectUrl parameter that points to a Trojan Horse client.zip update file.

Security readout for executives and security teams

CVE-2012-5003 affects No Machine NX Web Companion 3.x and earlier. Its Java applet update process did not properly confirm update authenticity. A remote attacker could trick a user into loading a crafted link that points the applet to a malicious client.zip update, leading to arbitrary code execution. Exposure is most likely in legacy environments still hosting or using NX Web Companion 3.x or earlier, especially web portals serving nxapplet.jar. Modern environments are unlikely to be exposed unless old NX Web Companion components remain deployed. Prioritize if NX Web Companion 3.x or earlier is still present. The business risk is remote code execution after user interaction. If the product is absent, no action is needed beyond confirming inventory. Mitigation focus: Inventory systems for NX Web Companion 3.x or earlier components.; Remove or disable obsolete NX Web Companion deployments where no longer required.; Check NoMachine or vendor guidance for supported upgrade or replacement options..
