| Vector | AV:N/AC:M/Au:N/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Java SE versions 7u311, 8u301, 11.0.12
Oracle GraalVM Enterprise Edition versions 20.3.3, 21.2.0
Description
The issue is related to the JSSE component and allows an unauthenticated attacker with network access via TLS to compromise Java SE and Oracle GraalVM Enterprise Edition. Successful attacks can result in unauthorized access to critical data or complete access to all accessible data. This issue applies to Java deployments that load and run untrusted code and rely on the Java sandbox for security. It can also be exploited through a web service that supplies data to the APIs.
Recommendations
For Java SE versions 7u311, 8u301, 11.0.12, update to a version that includes the fix for this issue.
For Oracle GraalVM Enterprise Edition versions 20.3.3, 21.2.0, update to a version that includes the fix for this issue.
As a temporary workaround, consider restricting access to the JSSE component until a patch is available.
Avoid using APIs in the specified component, e.g., through a web service, until the issue is resolved.
Fix
Use of a Broken Cryptographic Algorithm
