CVE-2018-25378 in Notebook Pro
Summary
by MITRE • 05/26/2026
Notebook Pro 2.0 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long string in the notebook name field. Attackers can create a malicious text file containing 500 or more characters, paste the content into the New Notebook Name field, and trigger an application crash when attempting to create and save the notebook.

This vulnerability represents a classic buffer overflow condition that occurs when the Notebook Pro 2.0 application fails to properly validate input length in the notebook name field. The flaw stems from inadequate bounds checking and string handling mechanisms within the application's user interface components, specifically affecting the input validation routines that process user-supplied data for notebook creation operations. The vulnerability manifests when attackers supply malicious input exceeding 500 characters, which causes the application to attempt memory allocation beyond its intended capacity, resulting in an unhandled exception that terminates the process.
The technical implementation of this denial of service vulnerability aligns with CWE-122 which describes improper restriction of operations within a limited memory buffer, and CWE-770 which addresses allocation of resources without limits or with inadequate limits. The attack vector operates through local privilege escalation where an authenticated user can exploit the application's failure to sanitize input before processing, making it particularly concerning for environments where multiple users share the same system resources. The vulnerability does not require elevated privileges to execute but rather relies on the application's inability to handle malformed input gracefully.
From an operational impact perspective, this vulnerability significantly undermines the application's reliability and availability, potentially affecting productivity in collaborative environments where multiple users create notebooks simultaneously. The crash condition prevents legitimate users from creating new notebooks and can result in data loss if the application fails to properly save state before termination. The vulnerability affects the core functionality of the application and can be exploited repeatedly, making it a persistent threat to system stability. Organizations relying on Notebook Pro 2.0 for research, development, or documentation activities may experience significant disruption when this vulnerability is exploited.
The recommended mitigation strategies include implementing robust input validation with strict character limit enforcement, incorporating proper memory management practices with bounds checking, and applying immediate patches or updates from the software vendor. Security teams should also consider implementing application whitelisting to restrict file creation operations and monitor for unusual input patterns in notebook creation activities. Additionally, the application should be configured with proper error handling mechanisms that prevent crashes from occurring when malformed input is detected, and input sanitization routines should be implemented to truncate or reject excessively long strings before they reach critical processing components. The ATT&CK framework categorizes this vulnerability under T1499 which covers network denial of service attacks, and T1059 which covers command and scripting interpreter usage, highlighting the need for comprehensive defensive measures across multiple attack surface areas.
