TestLink before v.1.9.20 is vulnerable to Cross Site Scripting (XSS) via the pop-up on upload file. When uploading a file, the XSS payload can be entered into the file name.
Multiple SQL injection vulnerabilities in TestLink through 1.9.19 allows remote authenticated users to execute arbitrary SQL commands via the (1) tproject_id parameter to keywordsView.php; the (2) req_spec_id parameter to reqSpecCompareRevisions.php; the (3) requirement_id parameter to reqCompareVersions.php; the (4) build_id parameter to planUpdateTC.php; the (5) tplan_id parameter to newest_tcversions.php; the (6) tplan_id parameter to tcCreatedPerUserGUI.php; the (7) tcase_id parameter to tcAssign2Tplan.php; or the (8) testcase_id parameter to tcCompareVersions.php. Authentication is often easy to achieve: a guest account, that can execute this attack, can be created by anyone in the default configuration.
TestLink before 1.9.20 allows XSS via non-lowercase javascript: in the index.php reqURI parameter. NOTE: this issue exists because of an incomplete fix for CVE-2019-19491.
Multiple cross-site scripting (XSS) vulnerabilities in TestLink before 1.9.14 allow remote attackers to inject arbitrary web script or HTML via the (1) selected_end_date or (2) selected_start_date parameter to lib/results/tcCreatedPerUserOnTestProject.php; the (3) containerType parameter to lib/testcases/containerEdit.php; the (4) filter_tc_id or (5) filter_testcase_name parameter to lib/testcases/listTestCases.php; the (6) useRecursion parameter to lib/testcases/tcImport.php; the (7) targetTestCase or (8) created_by parameter to lib/testcases/tcSearch.php; or the (9) HTTP Referer header to third_party/user_contribution/fakeRemoteExecServer/client4fakeXMLRPCTestRunner.php.
lib/execute/execSetResults.php in TestLink before 1.9.13 allows remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via the filter_result_result parameter.
lib/functions/database.class.php in TestLink before 1.9.13 allows remote attackers to obtain sensitive information via unspecified vectors, which reveals the installation path in an error message.
