CVE-2020-2215

Vulnerability

Overview

A cross-site request forgery (CSRF) vulnerability exists in the Jenkins Zephyr for JIRA Test Management Plugin versions 1.5 and earlier [1]. The root cause is a missing CSRF protection mechanism in the plugin's configuration form, specifically the action that handles connections to external HTTP servers [2].

Exploitation

Details

An attacker can exploit this flaw by crafting a malicious web page or link that, when visited by an authenticated Jenkins user, triggers a forged request to the Jenkins server [3]. The request would cause the Zephyr plugin to connect to an attacker-specified HTTP server using attacker-supplied username and password credentials [2]. No additional authentication is required beyond tricking an authenticated user into performing the action [1].

Impact

Successful exploitation allows the attacker to direct the Jenkins server to perform authenticated HTTP requests to an arbitrary external server under the attacker's control [3]. This could potentially lead to credential harvesting, data exfiltration, or use of the Jenkins server as a proxy for further attacks [1].

Mitigation

Status

The plugin vendor has not provided a fix, and the plugin is listed as having an unresolved security issue in the Jenkins security advisory published July 2, 2020 [1][2]. Users are advised to assess their use of the plugin and consider disabling or removing it until a patched version is released.
