Oracle Business Intelligence Enterprise Edition (OAS 7.6) (April 2026 CPU)

high Nessus Plugin ID 309965

Synopsis

The remote host is affected by multiple vulnerabilities

Description

The version of Oracle Business Intelligence Enterprise Edition (OAS) 7.6.0.0.0 installed on the remote host is affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

 - mchange-commons-java, a library that provides Java utilities, includes code that mirrors early implementations of JNDI functionality, including support for remote `factoryClassLocation` values, by which code can be downloaded and invoked within a running application. If an attacker can provoke an application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke the download and execution of malicious code. Implementations of this functionality within the JDK were disabled by default behind a System property that defaults to `false`, `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that implementation could be provoked to download and execute malicious code even after the JDK was hardened.
 Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions prior to 0.4.0 should be avoided on application CLASSPATHs. (CVE-2026-27727)

 - Eclipse Jersey 2.28 to 2.33 and Eclipse Jersey 3.0.0 to 3.0.1 contains a local information disclosure vulnerability. This is due to the use of the File.createTempFile which creates a file inside of the system temporary directory with the permissions: -rw-r--r--. Thus the contents of this file are viewable by all other users locally on the system. As such, if the contents written is security sensitive, it can be disclosed to other local users. (CVE-2021-28168)

 - In Connect2id Nimbus JOSE+JWT before 9.37.2, an attacker can cause a denial of service (resource consumption) via a large JWE p2c header value (aka iteration count) for the PasswordBasedDecrypter (PBKDF2) component. (CVE-2023-52428)

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

Solution

Apply the appropriate patch according to the April 2026 Oracle Critical Patch Update advisory.
