Description

evernote-mcp-server openBrowser Command Injection Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of evernote-mcp-server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the openBrowser function. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the service account. Was ZDI-CAN-27913.

Attack-Flow Graph

Executive Summary

This vulnerability is a command injection flaw in the openBrowser function of evernote-mcp-server. It occurs because the function does not properly validate a user-supplied string before using it in a system call. An attacker who already has the ability to execute low-privileged code on the system can exploit this flaw to escalate their privileges and execute arbitrary code with the permissions of the service account.

Impact Analysis

If exploited, this vulnerability allows an attacker with low-level access to escalate their privileges on the affected system. This means the attacker could gain higher-level permissions, potentially leading to full control over the system, unauthorized access to sensitive data, and the ability to execute arbitrary code, which could compromise system integrity and availability.
