CVE-2023-35141
Description
A flaw was found in Jenkins and Jenkins Long-Term Support (LTS), where it could allow a remote, authenticated attacker to bypass security restrictions caused by the inclusion of insufficiently escaped user-provided values in part of the URL. An attacker can send a POST request to an unexpected endpoint by persuading a victim to open a context menu.
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).
The following CVSS metrics and score provided are preliminary and subject to review.

Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism; Read Application Data; Modify Application Data; DoS: Crash, Exit, or Restart
The consequences will vary depending on the nature of the functionality that is vulnerable to CSRF. An attacker could trick a client into making an unintentional request to the web server via a URL, image load, XMLHttpRequest, etc., which would then be treated as an authentic request from the client - effectively performing any operations as the victim, leading to an exposure of data, unintended code execution, etc. If the victim is an administrator or privileged user, the consequences may include obtaining complete control over the web application - deleting or stealing data, uninstalling the product, or using it to launch other attacks against all of the product's users. Because the attacker has the identity of the victim, the scope of CSRF is limited only by the victim's privileges.
