Detailsinfo

A vulnerability, which was classified as critical, has been found in Appwrite up to 0.12.1. This issue affects some unknown functionality of the file APP_STORAGE_CERTIFICATES/.well-known/acme-challenge of the component ACME-Challenge Endpoint. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality. The summary by CVE is:

The ACME-challenge endpoint in Appwrite 0.5.0 through 0.12.x before 0.12.2 allows remote attackers to read arbitrary local files via ../ directory traversal. In order to be vulnerable, APP_STORAGE_CERTIFICATES/.well-known/acme-challenge must exist on disk. (This pathname is automatically created if the user chooses to install Let's Encrypt certificates via Appwrite.)

The weakness was published 02/23/2024. The advisory is shared at github.com. The identification of this vulnerability is CVE-2022-25377 since 02/20/2022. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
