Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Race condition (CVE-ID: CVE-2020-27216)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition. On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.


2) Improper input validation (CVE-ID: CVE-2020-27218)

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

The vulnerability exists due to improper input validation within the SC Admin server (Eclipse Jetty) component in Oracle Communications Converged Application Server - Service Controller. A remote non-authenticated attacker can exploit this vulnerability to manipulate or delete data.
