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 Jenkins 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 SECURITY-2448: High
o SECURITY-2765: High

o Git Plugin up to and including 4.11.4
o Job Configuration History Plugin up to and including 1165.v8cc9fd1f4597
