RCE vulnerability in Jenkins AWS SAM Plugin
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Maven | io.jenkins.plugins:aws-sam | < 1.2.3 | 1.2.3 |
Details
As written in the advisory (Markdown source, shown as plain text).
AWS SAM Plugin 1.2.2 and earlier 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 configure a job or control the contents of a previously configured \"AWS SAM deploy application\" build step’s YAML SAM template file (`template.yaml` or equivalent) file.
AWS SAM Plugin 1.2.3 configures its YAML parser to only instantiate safe types.
