A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 8.04 LTS

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)
