Detailsinfo

A vulnerability has been found in AOL Instant Messenger (Messaging Software) (unknown version) and classified as critical. This vulnerability affects an unknown code block of the component Script Handler. The manipulation with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The embedded Internet Explorer server control in AOL Instant Messenger (AIM) 6.1.41.2 and 6.2.32.1, AIM Pro, and AIM Lite does not properly constrain the use of mshtml.dll s web script and HTML functionality for incoming instant messages, which allows remote attackers to place HTML into unexpected contexts or execute arbitrary code, as demonstrated by writing arbitrary HTML to a notification window, and writing contents of arbitrary local image files to this window via IMG SRC.
