Summary
Improper Restriction of XML External Entity Reference vulnerability in XMLUtils.java in Slovensko.Digital Autogram allows remote unauthenticated attacker to conduct SSRF (Server Side Request Forgery) attacks and obtain unauthorized access to local files on filesystems running the vulnerable application. Successful exploitation requires the victim to visit a specially crafted website that sends request containing a specially crafted XML document to /sign endpoint of the local HTTP server run by the application.

Title
thinkgem JeeSite Endpoint CasOutHandler.java xml external entity reference
Summary
A flaw has been found in thinkgem JeeSite up to 5.15.1. Impacted is an unknown function of the file /com/jeesite/common/shiro/cas/CasOutHandler.java of the component Endpoint. Executing a manipulation can lead to xml external entity reference. The attack may be performed from remote. Attacks of this nature are highly complex. The exploitability is considered difficult. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Mitigation
Implementation
System Configuration
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
