Oracle release their "Critical Patch Update" (CPU) notices every quarter, bundling together details of vulnerabilities and associated patches across their entire product line. October's was released yesterday, with a few entries of note in the analytics & DI space.
Each vulnerability is given a unique identifier (
CVE-xxxx-xxxx) and a score out of ten. The scoring uses a common industry-standard scale on the basis of how easy it is to exploit, and what is compromised (availability, data, etc). Ten is the worst, and I would crudely paraphrase it as generally meaning that someone can wander in, steal your data, change your data, and take your system offline. Lower than that and it might be that it requires extensive skills to exploit, or the impact be much lower.
A final point to note is that the security patches that are released are not available for old versions of the software. For example, if you're on OBIEE 126.96.36.199 or earlier, and it is affected by the vulnerability listed below (which I would assume it is), there is no security patch. So even if you don't want to update your version for the latest functionality, staying within support is an important thing to do and plan for. You can see the dates for OBIEE versions and when they go out of "Error Correction Support" here.
If you want more information on how Rittman Mead can help you plan, test, and carry out patching or upgrades, please do get in touch!
The vulnerabilities listed below are not a comprehensive view of an Oracle-based analytics/DI estate - things like the database itself, along with Web Logic Server, should also be checked. See the CPU itself for full details.

- This vulnerability documents the potential that a developer could take the master repository schema credentials and use them to grant themselves SUPERVISOR access. Even using the secure wallet, the credentials are deobfuscated on the local machine and therefore a malicious developer could still access the credentials in theory.
