Published Aug 4, 2026 CVSS 4.0 · 9.3 Critical EPSS 1.3% KEV · Not listed

Description

Keysight IxChariot Endpoint before 9.5.102 contains a heap-based buffer overflow. An unauthenticated remote attacker can send a specially crafted packet to crash the endpoint or potentially execute arbitrary code.

Analysis

Technical impact

Keysight IxChariot Endpoint before 9.5.102 contains a heap-based buffer overflow that can be triggered by an unauthenticated remote attacker sending a specially crafted packet. This flaw can crash the endpoint or lead to arbitrary code execution, granting the attacker full control over the affected system.

Affected Systems

The vulnerability affects Keysight IxChariot Endpoint deployments running any version earlier than 9.5.102. Any version older than this is susceptible.

Risk and Exploitability

This flaw has a high severity CVSS score of 9.3. No EPSS data is available, and the vulnerability is not listed in CISA's KEV catalog, indicating it may not yet be actively exploited on a large scale. However, the attack requires only unauthenticated network access and can be performed remotely by crafting a malicious packet, meaning attackers could potentially gain arbitrary execution on the endpoint if the system is exposed to untrusted networks.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade the IxChariot Endpoint to version 9.5.102 or later, which contains the official fix for the buffer overflow.
If an immediate upgrade is not possible, restrict network access to the endpoint by applying firewall rules that block traffic from untrusted sources.
Apply any interim configuration changes recommended by Keysight, such as disabling unused services or reducing exposure to external network traffic, until the patch can be applied.
Continuously monitor for any new advisories from Keysight regarding the vulnerability.
