Security vulnerability in Oracle EBS : CVE-2021-44228

Posted by FatDBA on December 14, 2021

Hi All,

Recently while doing a database migration/upgrade project, we encountered a strange case where the orachk utility caught a new security vulnerability (CVE-2021-44228) on this new upgraded platform, and were related with customer’s logging platform log4j and for their EBS (E-business suite version 12.2) middleware. The vulnerability was for its JNDI features that do not protect against attacker controlled LDAP and other JNDI related endpoints, and coming with a 10 out of 10 severity score.

We checked with Oracle customer support and they asked us to apply a workaround (link below). I later on found that its not only Oracle products, but has impacted many other applications & cloud services. This weakness poses a significant risk to many applications and cloud services and it needs to be patched right away!
