Discussion

Netscape Communicator Javascript Sniffing Vulnerability

Netscape Communicator 4.x will allow javascript code in one browser window to read javascript data from another browser window, regardless of whether the two browsers are pointed to the same location or domain. This could allow a malicious webpage to open another browser pointing to another site, then record any information sent or retreived in the second browser. This could lead to credential or credit information theft.
