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.
