Multiple cross-site scripting (XSS) vulnerabilities in TestLink before 1.8 RC1 allow remote attackers to inject arbitrary web script or HTML via (1) Testproject Names and (2) Testplan Names in planEdit.php, and possibly (3) Testcaseprefixes in projectview.tpl.

Multiple cross-site scripting (XSS) vulnerabilities in TestLink before 1.8.5 allow remote attackers to inject arbitrary web script or HTML via (1) the req parameter to login.php, and allow remote authenticated users to inject arbitrary web script or HTML via (2) the key parameter to lib/general/staticPage.php, (3) the tableName parameter to lib/attachments/attachmentupload.php, or the (4) startDate, (5) endDate, or (6) logLevel parameter to lib/events/eventviewer.php; (7) the search_notes_string parameter to lib/results/resultsMoreBuilds_buildReport.php; or the (8) expected_results, (9) name, (10) steps, or (11) summary parameter in a find action to lib/testcases/searchData.php, related to lib/functions/database.class.php.
