Buffer Overflow RCE Nx

Description

A vulnerability has been identified in NX (All versions < V2512), NX (Managed Mode) (All versions < V2512). The affected application contains a data validation vulnerability that could allow an attacker with local access to interfere with internal data during the PDF export process that could potentially lead to arbitrary code execution.

Analysis

Nx versions prior to V2512 contain an insufficient input validation flaw in the PDF export functionality that permits local attackers to corrupt internal data structures and achieve arbitrary code execution. An attacker with local file system access can exploit this vulnerability to manipulate the export process and gain code execution privileges. …

Remediation

Within 24 hours: Inventory all NX deployments and identify systems running versions below V2512; document business criticality of each instance. Within 7 days: Implement network segmentation to restrict NX access, enforce multi-factor authentication for NX administrative access, and enable enhanced logging/monitoring. …
