- Subject: Communicator 4.5 stores EVERY mail-password in preferences.js
-
- Hi!
-
- The Netscape Communicator 4.5 stores the crypted version of used
- mail-passwords (for imap and pop3) even if you tell Netscape to *not*
- "remember password" in the preferences dialog.
-
- Damage:
- =======
- IMHO this means, that anybody who can read your preferences.js ("prefs.js"
- in the MS dominion) is problably able to read your mail or even get your
- plaintext-password.
-
- How to reproduce:
- =================
- - start Communicator
- - be sure "remember password" is disabled in the preferences dialog for the
- "Incoming Mail Server".
- - get mails from Server (you get asked for your mail-password)
- - exit Communicator
- - edit preferences.js in $HOME/.netscape (MS-Users: prefs.js in your
- NS-Profile-Path)
- - search for something like:
- --- 8< ---
- user_pref("mail.imap.server.mail.password", "cRYpTPaSswD=");
- user_pref("mail.imap.server.mail.remember_password", false);
- --- >8 ---
- - Now change "false" to "true".
- - Save the file
- - Start Communicator
- - get mails
-
- ... now you are not asked for any password but can read all your mail! :(
-
- Affected:
- =========
- probably all Communicator-4.5-packages on ALL operating systems.
-
- I was able to reproduce this behavior on:
- - Sun Solaris
- - Linux (glibc2)
- - MS Windows NT.
-
- Workaround:
- ===========
- Don't use Communicator 4.5 to fetch mails from your IMAP/POP server or be
- very sure that no one can read your Netscape-preferences-file!!!
-
- Regards,
- Holger van Lengerich, "pine"-user :)
-
- PS: The preferences.js is send to Netscape on Communicator-crash, isn't it?
