Mozilla Online Website Two Sub-Domains XSS (Cross-site Scripting) Bugs ( All URLs Under the Two Domains)
Two of Mozilla’s Cross Reference sub-domains suffer from a Cross-site Scripting (XSS) vulnerability, according to Jing Wang, a mathematics PhD student from School of Physical and Mathematical Science, Nanyang Technological University, Singapore.
Mozilla are dealing with the vulnerabilities.
Wang said “This means all URLs under the above two domains can be used for XSS attacks targeting Mozilla’s users,”
A reflected XSS attack is typically delivered via email or a neutral web site. The bait is an innocent-looking URL, pointing to a trusted site but containing the XSS vector. If the trusted site is vulnerable to the vector, clicking the link can cause the victim's browser to execute the injected script.
Spear-phishing qualifies for the most likely scenario where the attacker finds a developer with write permissions to some important Mozilla components and makes him (nr. the developer) click on a link that appears to be legitimate and from Mozilla. From here on, he can steal cookies, personal data, authentication credentials and browser history.
