Openproject: >> Openproject >> 16.6.6 Security Vulnerabilities
OpenProject is an open-source, web-based project management software. Prior to 17.0.2, users with the Manage Users permission can lock and unlock users. This functionality should only be possible for users of the application, but they were not supposed to be able to lock application administrators. Due to a missing permission check this logic was not enforced. The problem was fixed in OpenProject 17.0.2The problem was fixed in OpenProject 17.0.2.

OpenProject is an open-source, web-based project management software. Prior to versions 16.6.7 and 17.0.3, an arbitrary file write vulnerability exists in OpenProject’s repository changes endpoint (/projects/:project_id/repository/changes) when rendering the “latest changes” view via git log. By supplying a specially crafted rev value (for example, rev=--output=/tmp/poc.txt), an attacker can inject git log command-line options. When OpenProject executes the SCM command, Git interprets the attacker-controlled rev as an option and writes the output to an attacker-chosen path. As a result, any user with the :browse_repository permission on the project can create or overwrite arbitrary files that the OpenProject process user is permitted to write. The written contents consist of git log output, but by crafting custom commits the attacker can still upload valid shell scripts, ultimately leading to RCE. The RCE lets the attacker create a reverse shell to the target host and view confidential files outside of OpenProject, such as /etc/passwd. This issue has been patched in versions 16.6.7 and 17.0.3.

OpenProject is an open-source, web-based project management software. Prior to versions 16.6.7 and 17.0.3, an HTML injection vulnerability occurs in the time tracking function of OpenProject. The application does not escape HTML tags, an attacker with administrator privileges can create a work package with the name containing the HTML tags and add it to the Work package section when creating time tracking. This issue has been patched in versions 16.6.7 and 17.0.3.

OpenProject is an open-source, web-based project management software. Prior to 17.0.2, the drag&drop handler moving an agenda item to a different section was not properly checking if the target meeting section is part of the same meeting (or is the backlog, in case of recurring meetings). This allowed an attacker to move a meeting agenda item into a different meeting. The attacker did not get access to meetings, but they could add arbitrary agenda items, that could cause confusions. The vulnerability is fixed in 17.0.2.
