CVE-2017-20242

Keysight IxChariot Endpoint stack-based buffer overflow

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 stack-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

A stack-based buffer overflow exists in Keysight IxChariot Endpoint prior to version 9.5.102. An attacker who can send a specially crafted packet can trigger the overflow, which may cause the endpoint to crash or potentially allow the execution of arbitrary code. The flaw therefore threatens confidentiality, integrity, and availability by giving an attacker the ability to take full control of the device.

Affected Systems

All Keysight IxChariot Endpoint installations running a firmware version earlier than 9.5.102 are vulnerable. Any instance that has not applied the documented security update remains at risk.

Risk and Exploitability

The CVSS score of 9.3 reflects a high severity flaw that is exploitable remotely without authentication. No EPSS score is available, and the vulnerability is not listed in the CISA KEV catalog. The attack vector is inferred to be over the network, where an unauthenticated attacker can send malicious packets to a reachable endpoint port, leading to crash or code execution.

Affected Products

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

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade to a supported Keysight IxChariot release that contains the buffer overflow fix (any version 9.5.102 or newer).
If an upgrade is not immediately possible, block inbound traffic to the endpoint’s listening port using firewall rules to prevent attackers from sending malicious packets.
Continuously monitor the endpoint for abnormal crashes or packet anomalies that may indicate attempted exploitation.
