Subject: Big Flaw in Firefox 2: Password Manager Bug Exposes Passwords


"Today, Mozilla made public bug #360493, which exposes 
Firefox's Password Manager on many public sites. The flaw 
derives from Firefox's willingness to supply the username and 
password stored on one page on a domain to another page on a 
domain. For example, username/password input tags on a 
Myspace user's site will be unhelpfully propagated with the 
visitor's Myspace.com credentials. It was first discovered in 
the wild by Netcraft on Oct. 27. As this proof-of-concept 
illustrates, because the username/password fields need not be 
visible on the page, your password can be stolen in an almost 
completely transparent fashion. PoC here:

Looks like this also affects FireFox 1.5.08.
