CVE-2022-25193 in Snow Commander Plugin
Summary
by MITRE • 02/15/2022
Missing permission checks in Jenkins Snow Commander Plugin 2.0 and earlier allow attackers with Overall/Read permission to connect to an attacker-specified webserver using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

The vulnerability identified as CVE-2022-25193 represents a critical authorization bypass flaw within the Jenkins Snow Commander Plugin version 2.0 and earlier. This issue stems from insufficient permission validation mechanisms that allow unprivileged users to exploit the plugin's functionality in ways that were not intended by the developers. The flaw specifically affects systems where the Snow Commander plugin is installed and configured, creating a pathway for attackers to escalate their privileges through credential harvesting.
The technical implementation of this vulnerability resides in the plugin's handling of credential management and network communication functions. Attackers with only Overall/Read permission, which is typically considered a low-privilege level in Jenkins environments, can manipulate the plugin to establish connections to arbitrary web servers. The vulnerability exploits the absence of proper access control checks when processing credential IDs, allowing unauthorized users to leverage legitimate credential storage mechanisms to access sensitive authentication data. This misconfiguration enables the exploitation of stored credentials without requiring additional authorization levels that would normally be necessary to access such information.
The operational impact of CVE-2022-25193 extends beyond simple credential theft, as it provides attackers with potential access to multiple systems and services that rely on the compromised Jenkins credentials. When attackers successfully exploit this vulnerability, they can capture and potentially abuse credentials stored within Jenkins, which may include database access tokens, API keys, service account credentials, and other sensitive authentication materials. This capability significantly increases the attack surface and potential damage that can result from a successful compromise. The vulnerability is particularly concerning because it requires minimal privilege to exploit, making it accessible to users who should normally have restricted access to critical system resources.
Security professionals should consider this vulnerability in the context of the CWE-284 access control weakness classification, which specifically addresses improper access control mechanisms in software systems. The ATT&CK framework would categorize this as a privilege escalation technique under the T1078 legitimate credentials category, where adversaries leverage existing legitimate credentials to gain access to additional resources. Organizations should immediately implement mitigations including updating to the patched version of the Snow Commander plugin, implementing additional network segmentation controls, and conducting comprehensive credential reviews to identify any potential compromise. The vulnerability demonstrates the critical importance of proper permission validation and access control implementation in plugin architectures and highlights the need for thorough security testing of third-party integrations within Jenkins environments.
