Description
Description
In server mode pgAdmin 4 resolves a server's password file, SSL certificate, key, CRL and SSH tunnel identity file relative to the user's storage directory, but get_complete_file_path() only stripped leading slashes before joining the two. A path such as "../<another user>/.pgpass", set through the server dialog, the REST API or a servers.json import, therefore named another user's file, and connecting used that user's saved passwords, client certificate or SSH key. The sslkeylogfile connection parameter was passed to libpq unchanged, so a path outside storage let libpq create or append a file as the account running pgAdmin.
make_conninfo() also quoted connection parameter values but not their names, so a crafted parameter name could smuggle additional keyword=value pairs past these checks.
The fix requires the resolved path, with symbolic links followed, to stay inside the user's storage directory or the named shared storage directory, confines sslkeylogfile the same way, and accepts only exact libpq keywords as connection parameter names. A refused path or keyword is reported instead of letting libpq fall back to a default.
This issue affects pgAdmin 4: before 9.19.

KEV
| CWE ID | Description |
|---|---|
| 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. |
| CWE-73 | The product allows user input to control or influence paths or file names that are used in filesystem operations. |
