TestLink 1.9.20 is vulnerable to Incorrect Access Control in the TestPlan editing section. When a new TestPlan is created, an ID with an incremental value is automatically generated. Using the edit function you can change the tplan_id parameter to another ID. The application does not carry out a check on the user's permissions maing it possible to recover the IDs of all the TestPlans (even the administrative ones) and modify them even with minimal privileges.

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.

TestLink through 1.9.20 allows type juggling for authentication bypass because === is not used.

TestLink v1.9.20 was discovered to contain a Cross-Site Request Forgery (CSRF) via /lib/plan/planView.php.

TestLink v1.9.20 was discovered to contain a stored cross-site scripting (XSS) vulnerability via /lib/inventory/inventoryView.php.

TestLink 1.9.20 Raijin was discovered to contain a broken access control vulnerability at /lib/attachments/attachmentdownload.php

TestLink v1.9.20 was discovered to contain a SQL injection vulnerability via /lib/execute/execNavigator.php.

In TestLink 1.9.20, the lib/cfields/cfieldsExport.php goback_url parameter causes a security risk because it depends on client input and is not constrained to lib/cfields/cfieldsView.php at the web site associated with the session.

In TestLink 1.9.20, a crafted login.php viewer parameter exposes cleartext credentials.

An unrestricted file upload vulnerability in keywordsImport.php in TestLink 1.9.20 allows remote attackers to execute arbitrary code by uploading a file with an executable extension. This allows an authenticated attacker to upload a malicious file (containing PHP code to execute operating system commands) to a publicly accessible directory of the application.

A SQL injection vulnerability in TestLink 1.9.20 allows attackers to execute arbitrary SQL commands in planUrgency.php via the urgency parameter.

A SQL injection vulnerability in TestLink 1.9.20 allows attackers to execute arbitrary SQL commands in dragdroptreenodes.php via the node_id parameter.

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.

An issue was discovered in TestLink 1.9.19. The relation_type parameter of the lib/requirements/reqSearch.php endpoint is vulnerable to authenticated SQL Injection.

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.

TestLink 1.9.19 has XSS via the lib/testcases/archiveData.php edit parameter, the index.php reqURI parameter, or the URI in a lib/testcases/tcEdit.php?doAction=doDeleteStep request.

TestLink 1.9.19 has XSS via the error.php message parameter.

TestLink through 1.9.16 allows remote attackers to read arbitrary attachments via a modified ID field to /lib/attachments/attachmentdownload.php.

install/installNewDB.php in TestLink through 1.9.16 allows remote attackers to conduct injection attacks by leveraging control over DB LOGIN NAMES data during installation to provide a long, crafted value.

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.

SQL injection vulnerability in TestLink before 1.9.14 allows remote attackers to execute arbitrary SQL commands via the apikey parameter to lnl.php.

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.

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.

Multiple SQL injection vulnerabilities in TestLink 1.9.11 allow remote authenticated users to execute arbitrary SQL commands via the (1) name parameter in a Search action to lib/project/projectView.php or (2) id parameter to lib/events/eventinfo.php.

Multiple SQL injection vulnerabilities in TestLink 1.8.5b and earlier allow remote authenticated users with the Requirement view permission to execute arbitrary SQL commands via the req_spec_id parameter to (1) reqSpecAnalyse.php, (2) reqSpecPrint.php, or (3) reqSpecView.php in requirements/. NOTE: some of these details are obtained from third party information.
