Official description
SCG Policy Manager, all versions, contains an overly permissive Cross-Origin Resource Policy (CORP) vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to the execution of malicious actions on the application in the context of the authenticated user.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Permissive Cross-domain Security Policy with Untrusted Domains
The product uses a web-client protection mechanism such as a Content Security Policy (CSP) or cross-domain policy file, but the policy includes untrusted domains with which the web client is allowed to communicate.
How developers prevent this class of flaw
- Define a restrictive Content Security Policy or cross-domain policy file.
- Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.
- For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
