Description Preview

A vulnerability was discovered in MantisBT versions prior to 2.24.4 where an attacker with rights to create new issues could bypass access restrictions to clone private issues. The vulnerability exists in the bug_actiongroup.php file where a missing access check allows unauthorized users to use the COPY group action to create clones of private issues, including all associated bugnotes and attachments, by manipulating the bug_arr[] parameter. This security flaw enables attackers to access potentially confidential information stored in private issues or issues belonging to private projects.

Overview

CVE-2020-29604 is an authorization bypass vulnerability (CWE-862: Missing Authorization) in MantisBT, an open-source issue tracking system. The vulnerability allows users with basic issue creation permissions to access and clone private issues they should not have access to. By exploiting this vulnerability, an attacker can view sensitive information contained in private issues, including all notes and file attachments. This represents a significant confidentiality breach, as private issues often contain sensitive business information, security details, or personal data that should be restricted to authorized personnel only.

Remediation

To remediate this vulnerability, system administrators should:

  1. Upgrade MantisBT to version 2.24.4 or later, which includes the security patch addressing this vulnerability.
  2. If immediate upgrade is not possible, consider implementing access restrictions at the network or web server level to limit access to bug_actiongroup.php.
  3. Review access logs for potential exploitation of this vulnerability by checking for unusual COPY actions on private issues.
  4. Audit user permissions to ensure that only necessary users have issue creation rights.
  5. Consider temporarily disabling the COPY functionality if the patch cannot be applied immediately.
