Technical details
An arbitrary file deletion vulnerability exists in the JS Jobs (com_jsjobs) extension for Joomla, specifically within the 'job.savejob' task. The root cause is a lack of input validation in the 'storeJob' function in 'site/models/job.php', which processes custom user fields. An authenticated attacker can submit a POST request containing path traversal sequences (e.g., ../../) in the 'field_2' parameter. This input is passed to the 'unlink()' function in 'site/models/common.php' without sanitization, allowing the attacker to delete any file the web server has permissions to access, including 'configuration.php'. This vulnerability was originally identified in 2019 and affects version 1.2.6.
