CVE-2020-2601: Medium severity Oracle JDK vulnerability

Published Jan 13, 2020
·
Updated

It was discovered that the Kerberos implementation in the Security component of OpenJDK used RSA-MD5 checksum in Ticket Granting Service (TGS) requests even though MD5 algorithm is no longer considered safe for such use case. A remote attacker could possibly use this flaw to manipulate TGS requests.

Other sources

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Security). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Kerberos to compromise Java SE, Java SE Embedded. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).
