SAS XML Mapper 9.45 has an XML External Entity (XXE) vulnerability that can be leveraged by malicious attackers in multiple ways. Examples are Local File Reading, Out Of Band File Exfiltration, Server Side Request Forgery, and/or Potential Denial of Service attacks. This vulnerability also affects the XMLV2 LIBNAME engine when the AUTOMAP option is used.
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.
https://cwe.mitre.org/data/definitions/611.html →Open in CWE collection →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.
