Oracle WebCenter Portal Multiple Vulnerabilities (Apr 2020 CPU)

critical Nessus Plugin ID 135850
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

An application server installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Oracle WebCenter Portal installed on the remote host is missing a security patch from the April 2020 Critical Patch Update (CPU). It is, therefore, affected by the following vulnerabilities :

- A polymorphic typing exists in the jackson-databind component of the security framework of Oracle WebCenter Portal. An unauthenticated, remote attacker can exploit this, via an externally exposed RMI endpoint, to make the service execute a malicious payload. (CVE-2019-16943)

- A memory allocation issue exists in the Bouncy Castle Crypto library component of the security framework of Oracle WebCenter Portal. An unauthenticated, remote attacker can exploit this, via crafted ASN.1 data, to cause a partial denial of service condition. (CVE-2019-17359)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the April 2020 Oracle Critical Patch Update advisory.
