"Yoshihiro Ishikawa discovered that the Samba Web Administration Tool
(SWAT) was vulnerable to cross-site request forgeries (CSRF). If a
Samba administrator were tricked into clicking a link on a specially
crafted web page, an attacker could trigger commands that could modify
the Samba configuration. (CVE-2011-2522)

Nobuhiro Tsuji discovered that the Samba Web Administration Tool
(SWAT) did not properly sanitize its input when processing password
change requests, resulting in cross-site scripting (XSS)
vulnerabilities. With cross-site scripting vulnerabilities, if a user
were tricked into viewing server output during a crafted server
request, a remote attacker could exploit this to modify the contents,
or steal confidential data, within the same domain. (CVE-2011-2694).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
