Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Getgrav/grav, software state validation or input boundaries are circumvented during processing.

"details" : "### Summary\n\n- A low privilege user account with page editing privilege can read any server files using \"Frontmatter\" form.\n- This includes Grav user account files - /grav/user/accounts/*.yaml. This file stores hashed user password, 2FA secret, and the password reset token.\n- This can allow an adversary to compromise any registered account by resetting a password for a user to get access to the password reset token from the file or by cracking the hashed password.\n\n### Details\n_The vulnerability can be found in /user/plugins/form/templates/forms/fields/display/display.html.twig_\n\n\n\n### PoC\n1.\tThis PoC was conducted on Grav CMS version 1.7.46 and Admin Plugin version 1.10.46\n \n\n\n2.\tgo to “http://grav.local/admin/pages” then create new page with “Page Template” option set to “Form”.\n \n\n\n3.\tThen go to “Expert” and on Frontmatter input box used to following form template.\n\n\n\n4.\tSave page and go the preview or published page you will see the content of “/etc/passwd” file on the server.\n \n\n\n\n\n### Impact\nThis can allow a low privileged user to perform a full account takeover of other registered users including Administrators. This can also allow an adversary to read any file on the web server. And Due to insufficient permission verification , user who can write a page also can use frontmatter feature using this IDOR vulnerability [PoC IDOR](https://www.youtube.com/watch?v=EU1QA0idoWE&ab_channel=%EA%B9%80%EC%A2%85%EB%AF%BC) mention in [CVE-2024-2792](https://github.com/getgrav/grav/security/advisories/GHSA-f6g2-h7qv-3m5v)",
