Description Vincent Danen 2013-01-30 01:01:01 UTC
It was reported [1] that Samba's SWAT web configuration interface suffered from a potential cross-site request forgery (CSRF) vulnerability.

This is being fixed by using a random nonce stored in secrets.tdb.

This was an issue in the CSRF protection implementation that could possibly allow attacker to bypass existing CSRF protections if they knew victim's password.  CSRF protection was added in upstream version 3.5.10, see CVE-2011-2522 / bug 721348.
