New versions of Firefox exposed vulnerability usernames and passwords stolen

The latest version of Firefox and Safari has a password management security vulnerability. This security vulnerability allows some websites to access the stored user name and password.

Users who set the browser as a storage password or enable JavaScript are at risk, according to a message warning in the Full Disclosure mail list. Mozilla fixed a similar reverse cross-site scripting vulnerability in Firefox in last November. However, this security vulnerability is much more serious than the one found because it does not require JavaScript to be enabled.

The Heise Security company demonstrated this vulnerability on its website, allowing users to determine whether they are vulnerable to attacks.

However, some developers and critics have questioned whether the problem constitutes a security vulnerability in the browser, because such attacks require attackers to place a malicious code on the network server.

If attackers can place a script code on the server, attackers can manipulate webpages and steal data accessed by users. Before releasing a patch, you 'd better disable the JavaScript function in the browser or avoid using the password manager on a website that allows users to post JavaScript pages.
