CVE-2021-2163 edited at 24 Apr 2021 09:22:24
Type
- Arbitrary filesystem access
+ Insufficient validation
Description
+ A security issue was found in the way the Libraries component of OpenJDK enforced constraints defined in the jdk.jar.disabledAlgorithms security property. Verification of a JAR filed signed using a disabled algorithm could succeed in certain cases, leading to bypass of the intended security restrictions. The issue is fixed in versions 16.0.1, 11.0.11, 8u291 and 7u301.
- Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16; Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition accessible data.
-
- Note: This vulnerability applies to Java deployments that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.
