WsgiDAV is a generic and extendable WebDAV server based on WSGI. WsgiDAV 4.3.3 and prior can allow a WebDAV request path containing an encoded parent-directory segment to escape the configured filesystem share root in a specific path layout. The issue is fixed with version 4.3.4.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 0f5aaca7-c4d5-11f1-96b4-74563cf85f9d advisory.

    WsgiDAV is a generic and extendable WebDAV server based on                 WSGI. WsgiDAV 4.3.3 and prior can allow a WebDAV request path                 containing an encoded parent-directory segment to escape the                 configured filesystem share root in a specific path layout. The                 issue is fixed with version 4.3.4.
    WsgiDAV is a generic and extendable WebDAV server based on                 WSGI. Prior to 4.3.5, the sample MySQLBrowserProvider in                 wsgidav/samples/mysql_dav_provider.py concatenates the record key                 parsed from a request URL directly into SQL WHERE clauses. The                 affected _exists_record_by_primary_key, _get_field_by_primary_key,                 and _get_record_by_primary_key methods are part of a shipped                 example provider that is not enabled by default. An attacker who                 can access a share explicitly configured with this non-default                 provider can inject SQL through a normal GET request; anonymously                 exposed read shares permit a status-code oracle and extraction of                 arbitrary data reachable by the configured MySQL account. This                 issue is fixed in version 4.3.5.
    The WsgiDAV project reports:
    When follow_symlinks is false (the default), WsgiDAV is expected                 to prevent serving content through symbolic links - a request for                 a symlink returns 403 Forbidden: Symlink support is disabled.
                However, that guard inspects only the leaf component of the                 resolved path, and the root-containment check is purely lexical                 (os.path.abspath, which does not resolve symlinks).
    As a result, a symlink used as an intermediate directory in the                 request path is neither blocked by the guard nor caught by the                 containment check, and the request escapes the configured share                 root. This allows reading, writing, and deleting files outside the                 root.
