Description Jan Lieskovsky 2011-07-15 15:32:21 UTC

It was found that the 'Change Password' page / screen of the Samba Web Administration Tool did not properly sanitize content of the user-provided
"user" field, prior printing it back to the page content. A remote attacker could provide a specially-crafted URL, which once visited by an authenticated Samba SWAT user could allow the attacker to conduct cross-site scripting attacks (execute arbitrary HTML or script code).

Acknowledgements:

Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Nobuhiro Tsuji of NTT DATA SECURITY CORPORATION as the original reporter.
