Bug 127120

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.7)
Gecko/20040701 Firefox/0.9

Description of problem:
There may be a frame injection/spoofing security hole in Mozilla 1.6
and earlier, which could be used to assist in phishing attacks. Note
that there's a thread discussing this on the full-disclosure mailing
list; there seems to be some controversy as to whether this is really
a security hole. Nonetheless, Secunia claims it's fixed in Mozilla
1.7, and I can confirm that, insofar as Secunia's proof-of-concept
successfully changes a frame in mozilla-1.6-8 but not mozilla-1.7-0.3.2.

BTW, the Secunia advisory is here:
http://secunia.com/advisories/11978/


Version-Release number of selected component (if applicable):
mozilla-1.6-8

How reproducible:
Always

Steps to Reproduce:
1. Visit the Secunia test site:
http://secunia.com/multiple_browsers_frame_injection_vulnerability_test/
2. Follow the directions.
    

Actual Results:  Secunia contents are injected into MSDN site.

Expected Results:  MSDN site contents are not replaced with Secunia
contents.

Additional info:

One of the full-disclosure threads suggests that the attack may only
be possible if pop-up blocking is disabled. I tested Mozilla 1.7 with
pop-up blocking both enabled and disabled, and I tested Mozilla 1.6
with pop-up blocking disabled, but I have not tested Mozilla 1.6 with
pop-up blocking enabled.
