CVE-2018-10899
Description
A flaw was found in Jolokia, versions 1.2 through 1.6.0, where Jolokia did not correctly handle checking for origin and referrer headers when strict checking was enabled. An attacker could use this vulnerability to conduct cross-site request forgery or further attacks.
Statement
In Red Hat OpenStack Platform, jolokia is not enabled by default and, when enabled, the jolokia endpoints do not rely on CORS for security. Therefore, the impact has been reduced to Low and no updates will be provided at this time for the RHOSP jolokia package.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
An attacker could provide unexpected values and cause a program crash or arbitrary control of resource allocation, leading to excessive consumption of resources such as memory and CPU.
Confidentiality
Technical Impact: Read Memory; Read Files or Directories
An attacker could read confidential data if they are able to control resource references.
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
An attacker could use malicious input to modify data or possibly alter control flow in unexpected ways, including arbitrary command execution.
