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 4 Todd Cullum 2021-03-12 19:51:00 UTC

Upstream patch commit: https://github.com/apache/xmlgraphics-batik/commit/0ef5b661a1f77772d1110877ea9e0287987098f6
Upstream issue: https://issues.apache.org/jira/browse/BATIK-1284

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.

Comment 11 Jonathan Christison 2021-11-05 17:57:20 UTC

Although Baktik is distributed and used in Red Hat Fuse 7 we believe this vulnerability presents a low impact as the vulnerability occurs in Java Swing UI components of Batik (NodePickerPanel) and there is no use of this functionality.

Comment 12 errata-xmlrpc 2021-12-14 21:33:49 UTC
