Descriptions


Multiple XSS vulnerabilities
SECURITY-2781 / CVE-2022-34170 (SECURITY-2779), CVE-2022-34171 
(SECURITY-2761), CVE-2022-34172 (SECURITY-2776), CVE-2022-34173 
(SECURITY-2780)

Multiple cross-site scripting (XSS) vulnerabilities in Jenkins 2.355 and 
earlier, LTS 2.332.3 and earlier allow attackers to inject HTML and 
JavaScript into the Jenkins UI:

     SECURITY-2779 (CVE-2022-34170): Since Jenkins 2.320 and      LTS 
2.332.1, help icon tooltips no longer escape the      feature name, 
effectively undoing the fix for SECURITY-1955.

     SECURITY-2761 (CVE-2022-34171): Since Jenkins 2.321 and
      LTS 2.332.1, the HTML output generated for new symbol-based 
SVG icons includes the title attribute of l:ionicon until      Jenkins 
2.334 and alt attribute of l:icon since Jenkins      2.335 without 
further escaping.

     SECURITY-2776 (CVE-2022-34172): Since Jenkins 2.340, 
symbol-based icons unescape previously escaped values      of tooltip 
parameters.

     SECURITY-2780 (CVE-2022-34173): Since Jenkins 2.340, the 
tooltip of the build button in list views supports HTML      without 
escaping the job display name.

These vulnerabilities are known to be exploitable by attackers with 
Job/Configure permission.

Jenkins 2.356, LTS 2.332.4 and LTS 2.346.1 addresses these vulnerabilities:

     SECURITY-2779: The feature name in help icon tooltips is now escaped.

     SECURITY-2761: The title attribute of l:ionicon (Jenkins LTS 
2.332.4) and alt attribute of l:icon (Jenkins 2.356 and LTS 2.346.1) are 
escaped in the generated HTML output.

     SECURITY-2776: Symbol-based icons no longer unescape
values of tooltip parameters.

     SECURITY-2780: The tooltip of the build button in list views is now 
escaped.

	No Jenkins LTS release is affected by SECURITY-2776 or SECURITY-2780, 
as these were not present in Jenkins 2.332.x and fixed in the 2.346.x 
line before 2.346.1.


Observable timing discrepancy allows determining username validity
SECURITY-2566 / CVE-2022-34174

In Jenkins 2.355 and earlier, LTS 2.332.3 and earlier, an observable 
timing discrepancy on the login form allows distinguishing between login 
attempts with an invalid username, and login attempts with a valid 
username and wrong password, when using the Jenkins user database 
security realm. This allows attackers to determine the
validity of attacker-specified usernames.

Login attempts with an invalid username now validate a synthetic 
password to eliminate the timing discrepancy in Jenkins 2.356, LTS 2.332.4.


Unauthorized view fragment access
SECURITY-2777 / CVE-2022-34175

Jenkins uses the Stapler web framework to render its UI views. These 
views are frequently composed of several view fragments, enabling 
plugins to extend existing views with more content.

Before SECURITY-534 was fixed in Jenkins 2.186 and LTS 2.176.2, 
attackers could in some cases directly access a view fragment containing 
sensitive information, bypassing any permission checks in the 
corresponding view.

In Jenkins 2.335 through 2.355 (both inclusive), the protection added 
for SECURITY-534 is disabled for some views. As a result, attackers 
could in very limited cases directly access a view fragment containing 
sensitive information, bypassing any permission checks in the 
corresponding view.
	As of publication, the Jenkins security team is unaware of any 
vulnerable view fragment across the Jenkins plugin ecosystem.

Jenkins 2.356 restores the protection for affected views.


Stored XSS vulnerability in JUnit Plugin
SECURITY-2760 / CVE-2022-34176

JUnit Plugin 1119.va_a_5e9068da_d7 and earlier does not escape 
descriptions of test results.

This results in a stored cross-site scripting (XSS) vulnerability 
exploitable by attackers with Run/Update permission.

JUnit Plugin 1119.1121.vc43d0fc45561 applies the configured markup 
formatter to descriptions of test results.


Arbitrary file write vulnerability in Pipeline: Input Step Plugin
SECURITY-2705 / CVE-2022-34177

Pipeline: Input Step Plugin 448.v37cea_9a_10a_70 and earlier allows 
Pipeline authors to specify file parameters for Pipeline input steps 
even though they are unsupported. Although the uploaded file is not 
copied to the workspace, Jenkins archives the file on the controller as 
part of build metadata using the parameter name without sanitization as 
a relative path inside a build-related directory.

This allows attackers able to configure Pipelines to create or replace 
arbitrary files on the Jenkins controller file system with 
attacker-specified content.

Pipeline: Input Step Plugin 449.v77f0e8b_845c4 prohibits use of file 
parameters for Pipeline input steps. Attempts to use them will fail 
Pipeline execution.


Reflected XSS vulnerability in Embeddable Build Status Plugin
SECURITY-2567 / CVE-2022-34178

Embeddable Build Status Plugin 2.0.3 allows specifying a link query 
parameter that build status badges will link to, without restricting 
possible values.

This results in a reflected cross-site scripting (XSS) vulnerability.

Embeddable Build Status Plugin 2.0.4 limits URLs to http and https 
protocols and correctly escapes the provided value.


Path traversal vulnerability in Embeddable Build Status Plugin
SECURITY-2792 / CVE-2022-34179

Embeddable Build Status Plugin 2.0.3 and earlier allows specifying a 
style query parameter that is used to choose a different SVG image style 
without restricting possible values.

This results in a relative path traversal vulnerability, allowing 
attackers without Overall/Read permission to specify paths to other SVG 
images on the Jenkins controller file system.

Embeddable Build Status Plugin 2.0.4 restricts the style query parameter 
to one of the three legal values.


Improper authorization in Embeddable Build Status Plugin bypasses 
ViewStatus permission requirement
SECURITY-2794 / CVE-2022-34180

Embeddable Build Status Plugin 2.0.3 and earlier does not correctly 
perform the ViewStatus permission check in the HTTP endpoint it provides 
for "unprotected" status badge access.

This allows attackers without any permissions to obtain the build status 
badge icon for any attacker-specified job and/or build.

Embeddable Build Status Plugin 2.0.4 requires ViewStatus permission to 
obtain the build status badge icon.


Agent-to-controller security bypass in xUnit Plugin
SECURITY-2549 / CVE-2022-34181

xUnit Plugin 3.0.8 and earlier implements an agent-to-controller message 
that creates a user-specified
directory if it doesn’t exist, and parsing files inside it as test results.

This allows attackers able to control agent processes to create an 
arbitrary directory on the Jenkins controller or to obtain test results 
from existing files in an attacker-specified directory.

xUnit Plugin 3.1.0 changes the message type from agent-to-controller to 
controller-to-agent, preventing execution on the controller.


Reflected XSS vulnerability in Nested View Plugin
SECURITY-2768 / CVE-2022-34182

Nested View Plugin 1.20 through 1.25 (both inclusive) does not escape 
search parameters.

This results in a reflected cross-site scripting (XSS) vulnerability.

Nested View Plugin 1.26 escapes search parameters.


Stored XSS vulnerabilities in multiple plugins providing additional 
parameter types
SECURITY-2784 / CVE-2022-34183 (Agent Server Parameter), CVE-2022-34184 
(CRX Content Package Deployer), CVE-2022-34185 (Date Parameter), 
CVE-2022-34186 (Dynamic Extended Choice Parameter), CVE-2022-34187 
(Filesystem List Parameter), CVE-2022-34188 (Hidden Parameter), 
CVE-2022-34189 (Image Tag Parameter), CVE-2022-34190 (Maven Metadata for 
CI server), CVE-2022-34191 (NS-ND Integration Performance Publisher), 
CVE-2022-34192 (ontrack Jenkins), CVE-2022-34193 (Package Version), 
CVE-2022-34194 (Readonly Parameter), CVE-2022-34195 (Repository 
Connector), CVE-2022-34196 (REST List Parameter), CVE-2022-34197 (Sauce 
OnDemand), CVE-2022-34198 (Stash Branch Parameter)

Multiple plugins do not escape the name and description of the parameter 
types they provide:

     Agent Server Parameter 1.1 and earlier (SECURITY-2731 / CVE-2022-34183)

     CRX Content Package Deployer 1.9 and earlier (SECURITY-2727 / 
CVE-2022-34184)

     Date Parameter Plugin 0.0.4 and earlier (SECURITY-2711 / 
CVE-2022-34185)

     Dynamic Extended Choice Parameter 1.0.1 and earlier (SECURITY-2712 
/ CVE-2022-34186)

     Filesystem List Parameter 0.0.7 and earlier (SECURITY-2716 / 
CVE-2022-34187)

     Hidden Parameter Plugin 0.0.4 and earlier (SECURITY-2755 / 
CVE-2022-34188)

     Image Tag Parameter 1.10 and earlier (SECURITY-2721 / CVE-2022-34189)

     Maven Metadata for CI server 2.1 and earlier (SECURITY-2714 / 
CVE-2022-34190)

     NS-ND Integration Performance Publisher 4.8.0.77 and earlier 
(SECURITY-2736 / CVE-2022-34191)

     ontrack Jenkins 4.0.0 and earlier (SECURITY-2733 / CVE-2022-34192)

     Package Version 1.0.1 and earlier (SECURITY-2735 / CVE-2022-34193)

     Readonly Parameter 1.0.0 and earlier (SECURITY-2719 / CVE-2022-34194)

     Repository Connector 2.2.0 and earlier (SECURITY-2666 / CVE-2022-34195)

     REST List Parameter Plugin 1.5.2 and earlier (SECURITY-2730 / 
CVE-2022-34196)

     Sauce OnDemand 1.204 and earlier (SECURITY-2724 / CVE-2022-34197)

     Stash Branch Parameter 0.3.0 and earlier (SECURITY-2725 / 
CVE-2022-34198)


This results in stored cross-site scripting (XSS) vulnerabilites 
exploitable by attackers with Item/Configure permission.

Exploitation of these vulnerabilities requires that parameters are 
listed on another page, like the "Build With Parameters" and 
"Parameters" pages provided by Jenkins (core), and that those pages are 
not hardened to prevent exploitation. Jenkins (core) has prevented 
exploitation of vulnerabilities of this kind on the "Build With 
Parameters" and "Parameters" pages since 2.44 and LTS 2.32.2 as part of 
the SECURITY-353 / CVE-2017-2601 fix. Additionally, several plugins have 
previously been updated to list parameters in a way that prevents 
exploitation by default, see SECURITY-2617 in the 2022-04-12 security 
advisory for a list.

The following plugins have been updated to escape the name and 
description of the parameter types they provide in the versions specified:

     REST List Parameter Plugin 1.6.0

     Hidden Parameter Plugin 0.0.5

As of publication of this advisory, there is no fix available for the 
following plugins:
