Details

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)
