CVE-2019-19394 - Mission Portal JavaScript Injection vulnerability

A vulnerability was recently discovered in CFEngine Mission Portal and has now been fixed. Under certain circumstances, it was possible to inject JavaScript code into data presented in Mission Portal, that would be run in the user’s browser. This security issue was fixed in CFEngine 3.10.7, 3.12.3, and 3.15.0, and will be mitigated by upgrading your hub to one of these versions (or later). No other action is required than upgrading the Hub.

CFEngine 3.12.2-3, 3.14.0-2 released (mitigating CVE-2019-10164)

On [2019-07-29 Mon] we released new builds of our Enterprise Hub packages for 3.12.2 and 3.14.0. This release addresses CVE-2019-10164. PostgreSQL versions 10.x before 10.9 and versions 11.x before 11.4 are vulnerable to a stack-based buffer overflow. Any authenticated user can overflow a stack-based buffer by changing the user’s own password to a purpose-crafted value. This often suffices to execute arbitrary code as the PostgreSQL operating system account. CFEngine Enterprise LTS versions 3.

CVE-2019-9929 - internal authentication secrets leaked in logs

Description The CFEngine engineering team has recently discovered a severe security issue in the CFEngine Enterprise product. CFEngine is using some internal secrets for authentication to the Mission Portal API and the PostgreSQL database when running background maintenance tasks. These internal secrets are randomly generated during the installation process and stored in files which only the root user has access to. Unfortunately, the commands that generate and store the secrets were being logged to the /var/log/CFEngineHub-Install.

POODLE, SSLv3 and CFEngine

This post clarifies whether CFEngine is affected by the newly published vulnerability in the SSL protocol, POODLE. CFEngine core functionality, i.e. agent-to-hub communication is not affected in any way by the POODLE vulnerability. If the protocol version is set to “classic” or “1”, or is just left to be the default, then all communication happens using the legacy protocol which has nothing to do with SSL. If it is set to “latest” or “2”, then TLS version 1.
