Oracle · Oracle Java Se · CVE-2023-21939
**Name of the Vulnerable Software and Affected Versions**
Oracle Java SE versions 8u361, 8u361-perf, 11.0.18, 17.0.6, 20
Oracle GraalVM Enterprise Edition versions 20.3.9, 21.3.5, 22.3.1
**Description**
The issue exists due to insufficient input validation in the Swing component of Oracle Java SE and Oracle GraalVM Enterprise Edition. This allows an unauthenticated attacker with network access via HTTP to compromise the system, resulting in unauthorized update, insert, or delete access to some accessible data. The vulnerability applies to Java deployments that load and run untrusted code and rely on the Java sandbox for security. It can also be exploited through APIs in the specified component, such as through a web service that supplies data to the APIs.
**Recommendations**
For Oracle Java SE versions 8u361, 8u361-perf, 11.0.18, 17.0.6, 20, and Oracle GraalVM Enterprise Edition versions 20.3.9, 21.3.5, 22.3.1, consider disabling the Swing component until a patch is available.
Restrict access to the vulnerable APIs in the specified component to minimize the risk of exploitation.
Avoid using the affected Oracle Java SE and Oracle GraalVM Enterprise Edition versions in environments where untrusted code is executed.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
