Description Guilherme de Almeida Suckevicz 2021-03-01 18:53:43 UTC
Apache Batik 1.13 is vulnerable to server-side request forgery, caused by improper input validation by the NodePickerPanel. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.

Comment 6 Todd Cullum 2021-03-12 19:58:21 UTC
Flaw summary:

NodePickerPanel in batik was configured to load XML external Document Type Definitions (DTDs) and XML external entities. This allowed for crafted input to result in server-side request forgery, allowing an attacker to make arbitrary GET requests from the server. The patch disables external-general-entities, external-parameter-entities, and load-external-dtd in NodePickerPanel to prevent this.

Comment 7 Todd Cullum 2021-03-12 19:58:37 UTC
Mitigation:

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
