New York Times Page Design XSS Vulnera


New York Times Page Design XSS Vulnerability (Almost all Article Pages Before 2013 are Affected)







Vulnerability Description:

The vulnerability occurs at New York Times’s URLs. Nytimes (short for New York Times) uses part of the URLs to construct its pages. However, it seems that Nytimes does not filter the content used for the construction at all before 2013.


Based on Nytimes’s Design, Almost all URLs before 2013 are affected (All pages of articles). In fact, all article pages that contain “PRINT” button, “SINGLE PAGE” button, “Page *” button, “NEXT PAGE” button are affected.


Nytimes changed this mechanism since 2013. It decodes the URLs sent to its server. This makes the mechanism much safer now.


However, all URLs before 2013 are still using the old mechanism. This means almost all article pages before 2013 are still vulnerable to XSS attacks. I guess the reason Nytimes does not filter URLs before is cost. It costs too much (money & human capital) to change the database of all posted articles before.

The vulnerability can be attacked without user login. Tests were performed on Firefox (26.0) in Ubuntu (12.04) and IE (9.0.15) in Windows 7.






Cross-site scripting (XSS) is a type of computer security vulnerability typically found in Web applications. XSS enables attackers to inject client-side script into Web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same origin policy.
