Frequently Asked Questions
Which deployments are most exposed to this issue?
Network-reachable applications that pass attacker-controlled data to JAXP APIs, such as web services, are exposed. Java client deployments running sandboxed Java Web Start applications or sandboxed applets that load untrusted internet-sourced code are also affected.
What does an attacker need to exploit it?
The attacker does not need authentication or user interaction, but needs network access through one of multiple protocols. Exploitation is rated difficult and can occur through APIs in the affected JAXP component when supplied data reaches those APIs.
What is the potential impact of a successful attack?
A successful attack can give unauthorized access to critical data or complete access to data accessible to the affected Oracle Java SE or GraalVM deployment.
Which versions are identified as affected?
Affected Oracle Java SE versions are 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, and 27. Affected Oracle GraalVM for JDK versions are 17.0.20.1 and 21.0.12.1; affected Oracle GraalVM Enterprise Edition version is 21.3.19.1.1.
