Technical details
The vulnerability exists in the Java implementation within Netscape Navigator 4.5, where the 'Same-Origin Policy' for network connections is not strictly enforced for Java applets. Under the standard Java security model, an applet should be restricted to making network connections only back to its host of origin. Due to this flaw, a remote attacker can host a malicious applet that, when executed in a victim's browser, initiates unauthorized network connections to third-party hosts. This can be leveraged for cross-site scanning or interacting with internal network services that are otherwise inaccessible to the attacker.
