Jenkins Jabber (XMPP) notifier and control Plugin 1.41 and earlier stores passwords unencrypted in its global configuration file on the Jenkins controller where they can be viewed by users with access to the Jenkins controller file system.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Jenkins Jabber (XMPP) notifier and control Plugin 1.41 and earlier stores passwords unencrypted in its
    global configuration file on the Jenkins controller where they can be viewed by users with access to the
    Jenkins controller file system. (CVE-2021-21634)

According to their self-reported version numbers, the versions of Jenkins plugins running on the remote web server are Jenkins Build With Parameters Plugin prior to 1.5.1, Cloud Statistics Plugin prior to 0.27, Extra Columns Plugin prior to 1.23, Jabber (XMPP) notifier and control Plugin prior to 1.42, OWASP Dependency-Track Plugin prior to 3.1.1, REST List Parameter Plugin prior to 1.3.1, or Team Foundation Server Plugin 5.157.1 or earlier. They are, therefore, affected by multiple vulnerabilities:

  - Jenkins Build With Parameters Plugin 1.5 and earlier does not escape parameter names and descriptions,     resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Job/Configure     permission. (CVE-2021-21628)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins Build With Parameters Plugin 1.5 and earlier     allows attackers to build a project with attacker-specified parameters. (CVE-2021-21629)

  - Jenkins Extra Columns Plugin 1.22 and earlier does not escape parameter values in the build parameters     column, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with     Job/Configure permission. (CVE-2021-21630)

  - Jenkins Cloud Statistics Plugin 0.26 and earlier does not perform a permission check in an HTTP endpoint,     allowing attackers with Overall/Read permission and knowledge of random activity IDs to view related     provisioning exception error messages. (CVE-2021-21631)

  - A missing permission check in Jenkins OWASP Dependency-Track Plugin 3.1.0 and earlier allows attackers     with Overall/Read permission to connect to an attacker-specified URL, capturing credentials stored in     Jenkins. (CVE-2021-21632)

  - A cross-site request forgery (CSRF) vulnerability in Jenkins OWASP Dependency-Track Plugin 3.1.0 and     earlier allows attackers to connect to an attacker-specified URL, capturing credentials stored in Jenkins.
    (CVE-2021-21633)

  - Jenkins Jabber (XMPP) notifier and control Plugin 1.41 and earlier stores passwords unencrypted in its     global configuration file on the Jenkins controller where they can be viewed by users with access to the     Jenkins controller file system. (CVE-2021-21634)

  - Jenkins REST List Parameter Plugin 1.3.0 and earlier does not escape a parameter name reference in     embedded JavaScript, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by     attackers with Job/Configure permission. (CVE-2021-21635)

  - A missing permission check in Jenkins Team Foundation Server Plugin 5.157.1 and earlier allows attackers     with Overall/Read permission to enumerate credentials ID of credentials stored in Jenkins.
    (CVE-2021-21636)

  - A missing permission check in Jenkins Team Foundation Server Plugin 5.157.1 and earlier allows attackers     with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials     IDs obtained through another method, capturing credentials stored in Jenkins. (CVE-2021-21637)
