Title: Netscape Navigator Embedded Image URI Obfuscation Weakness
Severity: HIGH
Description:
Netscape is a web browser that is available for a number of platforms, including Microsoft Windows and Unix and Linux variants.
It is reported that Netscape Navigator is prone to a URI obfuscation weakness that may hide the true contents of a URI link. The issue occurs when an image is contained within a HREF tag, this image is then later mapped so that the HREF of the image map points to an alternate site. The MAP HREF appears to take priority over the originally specified HREF for the image, resulting in obfuscation of the true URI in both the status bar and the mouseover tooltip.
This weakness could be employed to trick a user into following a malicious link.
An attacker can exploit this issue by supplying a malicious image that appears to be a URI link pointing to a page designed to mimic that of a trusted site. If an unsuspecting victim is to mouseover the link in an attempt to verify the authenticity of where it references, they may be deceived into believing that the link references the actual trusted site. This could potentially cause a false sense of security for the victim.
Affected Products:
- Netscape Navigator 7.1.0
