Jenkins Security Advisory 2022-08-23
This advisory announces vulnerabilities in the following Jenkins 
deliverables:

   o CollabNet Plugins Plugin
   o Git Plugin
   o Job Configuration History Plugin
   o Kubernetes Continuous Deploy Plugin


Descriptions
Improper masking of credentials in Git Plugin
SECURITY-2796 / CVE-2022-38663
Severity (CVSS): Medium
Affected plugin: git


Description:

Git Plugin 4.11.4 and earlier does not properly mask (i.e., replace with 
asterisks) credentials in the build log provided by the Git Username and 
Password (gitUsernamePassword) credentials binding. Usernames are masked 
instead of passwords in cases when usernames are not set to be treated 
as secret.

Git Plugin 4.11.5 properly masks credentials in the build log provided 
by the Git Username and Password (gitUsernamePassword) credentials 
binding. As a side effect of the fix, usernames currently set to be not 
masked will lose their
current (unintentional) masking.


Stored XSS vulnerability in Job Configuration History Plugin
SECURITY-2765 / CVE-2022-38664
Severity (CVSS): High
Affected plugin: jobConfigHistory

Description:

Job Configuration History Plugin 1165.v8cc9fd1f4597 and earlier
does not escape the job name on the System Configuration History page.

This results in a stored cross-site scripting (XSS) vulnerability 
exploitable by attackers able to configure job names.

Job Configuration History Plugin 1166.vc9f255f45b_8a escapes the
job name on the System Configuration History page.

RabbitMQ password stored in plain text by CollabNet Plugins Plugin
SECURITY-2157 / CVE-2022-38665
Severity (CVSS): Low
Affected plugin: collabnet

Description:

CollabNet Plugins Plugin 2.0.8 and earlier stores a RabbitMQ password 
unencrypted in its global configuration file
hudson.plugins.collabnet.share.TeamForgeShare.xml on the J
enkins controller as part of its configuration.

This password can be viewed by users with access to the Jenkins 
controller file system.

CollabNet Plugins Plugin 2.0.9 no longer includes the EventQ feature 
that accepts RabbitMQ credentials. The RabbitMQ password will be removed 
from the configuration file once it is saved again.


RCE vulnerability in Kubernetes Continuous Deploy Plugin
SECURITY-2448 / CVE-2021-25738
Severity (CVSS): High
Affected plugin: kubernetes-cd

Description:

Kubernetes Continuous Deploy Plugin 2.3.1 and earlier bundles a version 
of Kubernetes Java Client library with the vulnerability CVE-2021-25738 
that does not configure its YAML parser to prevent the instantiation of 
arbitrary types.

This results in a remote code execution (RCE) vulnerability exploitable 
by users able to provide YAML input files to Kubernetes Continuous 
Deploy Plugin's build step.

As of publication of this advisory, there is no fix.


Severity

   o Kubernetes Continuous Deploy Plugin up to and including 2.3.1

Fix
   o CollabNet Plugins Plugin should be updated to version 2.0.9
