Description

Arbitrary file write vulnerability in Jenkins Pipeline: Input Step Plugin

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity high, availability none.

Weakness class

CVE-2022-34177 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
