CVE-2007-2383 low priority: Ubuntu including 1 source packages (libhtml-prototype-perl), 4 status rows across 4 suites (dapper, edgy, feisty, upstream): ignored 3, needs-triage 1.
The Prototype (prototypejs) framework before 1.5.1 RC3 exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."
