CloudBees Security Advisory 2022-02-15

SECURITY-2463 / CVE-2022-25173 (Pipeline: Groovy Plugin), CVE-2022-25174 (Pipeline: Shared Groovy Libraries), CVE-2022-25175 (Pipeline: Multibranch)

Multiple Pipeline-related plugins that perform on-controller SCM checkouts reuse the same workspace directory for checkouts of distinct SCMs in some contexts.

• Pipeline: Groovy Plugin 2648.va9433432b33c and earlier uses the same checkout directories for distinct SCMs when reading the script file (typically Jenkinsfile) for Pipelines.

• Pipeline: Shared Groovy Libraries 552.vd9cc05b8a2e1 and earlier uses the same checkout directories for distinct SCMs for Pipeline libraries.

• Pipeline: Multibranch 706.vd43c65dec013 and earlier uses the same checkout directories for distinct SCMs for the readTrusted step.

This allows attackers with Item/Configure permission to invoke arbitrary OS commands on the controller through crafted SCM contents.

Affected plugins have been updated to address these issues:

• Pipeline: Groovy Plugin 2656.vf7a_e7b_75a_457 uses distinct checkout directories per SCM when reading the script file (typically Jenkinsfile) for Pipelines.

• Pipeline: Shared Groovy Libraries 561.va_ce0de3c2d69 uses distinct checkout directories per SCM for Pipeline libraries.

• Pipeline: Multibranch 707.v71c3f0a_6ccdb_ uses distinct checkout directories per SCM for the readTrusted step.

SECURITY-2613 / CVE-2022-25176 (Pipeline: Groovy Plugin), CVE-2022-25177 (Pipeline: Shared Groovy Libraries), CVE-2022-25178 (Pipeline: Shared Groovy Libraries), CVE-2022-25179 (Pipeline: Multibranch)

Multiple Pipeline-related plugins follow symbolic links or do not limit path names, resulting in arbitrary file read vulnerabilities:

• Pipeline: Groovy Plugin 2648.va9433432b33c and earlier follows symbolic links to locations outside of the checkout directory for the configured SCM when reading the script file (typically Jenkinsfile) for Pipelines (originally reported as SECURITY-2595).

• Pipeline: Shared Groovy Libraries 552.vd9cc05b8a2e1 and earlier follows symbolic links to locations outside of the expected Pipeline library when reading files using the libraryResource step (originally reported as SECURITY-2479).

• Pipeline: Shared Groovy Libraries 552.vd9cc05b8a2e1 and earlier does not restrict the names of resources passed to the libraryResource step (originally reported as SECURITY-2476).

• Pipeline: Multibranch 706.vd43c65dec013 and earlier follows symbolic links to locations outside of the checkout directory for the configured SCM when reading files using the readTrusted step (originally reported as SECURITY-2491).

This allows attackers able to configure Pipelines to read arbitrary files on the Jenkins controller file system.

Affected plugins have been updated to address these issues:

• Pipeline: Groovy Plugin 2656.vf7a_e7b_75a_457 checks that the script file for Pipelines is inside of the checkout directory for the configured SCM.

• Pipeline: Shared Groovy Libraries 561.va_ce0de3c2d69 checks that any resources retrieved by the libraryResource step are contained within the expected Pipeline library.

• Pipeline: Multibranch 707.v71c3f0a_6ccdb_ checks that the file retrieved by readTrusted is inside of the checkout directory for the configured SCM.

SECURITY-2443 / CVE-2022-25180
