A vulnerability in Mozilla Firefox may allow a remote attacker to install malicious code on or read protected information from a vulnerable system.
The Firefox web browser features the ability to open a hyperlink in the “search” web panel. Firefox fails to perform adequate security checks on links opened in the web panel. According to the Mozilla advisory on this issue:
Sites can use the _search target to open links in the Firefox sidebar. Two missing security checks allow malicious scripts to first open a privileged page (such as about:config) and then inject script using a javascript: url. This could be used to install malicious code or steal data without user interaction.
Updated versions of the Firefox browser disallow javascript:
and data:
URIs from being opened in the search Web panel. They also perform an additional security check to prevent privileged pages, such as about:plugins
, from being opened in the search Web panel.
A remote attacker may be able to install malicious code on or read protected information from a vulnerable system.
