[Resolved] cross-site-scripting at wellsfargo.com

Post by larryhg »

While attempting to log in to wellsfargo at https://www.wellsfargo.com/, a NoScript rule seems to be triggered:

Code: Select all

[NoScript XSS] Sanitized suspicious upload to [https://online.wellsfargo.com/signon###DATA###...
Steps to reproduce:
1) Visit https://www.wellsfargo.com/
2) In the login pane on the left, attempt to log in with any credentials -- for example, username: a, password: b.
3) My browser is redirected to https://online.wellsfargo.com/signon with a NoScript warning message.
4) Note that if you attempt to log in from this page (https://online.wellsfargo.com/signon) with invalid credentials, NoScript is not triggered and you see an error message "You have entered an invalid username. Please re-enter your username.".

Is the problem caused by NoScript's InjectionChecker regex or something else local to my machine?

Thank you.

Well, I'm not an expert on the ins and outs, but from what I can see:
  • Wells Fargo is attempting to spy on your browser details, available plugins, etc.
  • Some of the details that it is trying to grab include snippets of HTML.
  • NoScript doesn't like the inclusion of this HTML in requests, since it tends to be associated with Cross-Site Scripting attacks.
I suggest bookmarking the second page and exclusively using that.

And anyway latest development builds are fine-tuned to allow "innocuous" anchors to be included in the request, thus removing this false positive.

i use "wellfargo.com" and, the last time that i tried to log in to the website, i had problems, too, but i didn't know what the problem was.. i had never had problems with logging into the website, before..

when i first noticed the problem, where my login failed, i figured that i must have accidentally entered the wrong credentials..

i kept trying to log in to the website and eventually i was able to log in..

p.s. i logged in to "wellsfargo.com" just now and didn't have any problems with it..

i am using "noscript build 2.6.8.11"..
