CVE-2023-32981
Description
A flaw was found in the Jenkins Pipeline Utility Steps Plugin. This flaw allows a remote, authenticated attacker to traverse directories on the system, caused by improper archive file validation. The attacker can use a specially crafted archive file containing "dot dot" sequences (/../) to create or replace arbitrary files on the agent file system with attacker-specified content.
Statement
OpenShift 3.11 is in ELS. Jenkins and its related technologies will not be supported under ELS. Hence, OpenShift 3.11 is marked as affected/won'tfix.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Red Hat CVSS v3 Score Explanation
- As per upstream, This flaw allows a remote, authenticated attacker to traverse directories on the system. Hence, PR:L. Confidentiality, Integrity, and Availability metrics are Low, because:
- Successful exploitation may lead to some loss of confidentiality, but it's not under the attacker's control what information will be obtained.
- Theoretically, an attacker may be able to modify some data but does not have control over the consequences of that modification.
- An attacker is not able to determine if successful exploitation will affect the availability of the target environment.
