CVE-2024-53676: HPE Insight Remote Support path traversal allows remote code execution

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

critical priorityCVSS 9.8 with network reachability, no authentication and no user interaction, combined with a 99th percentile EPSS score, makes this an urgent patch target despite the thin description.

What it is

Hewlett Packard Enterprise Insight Remote Support contains a directory traversal flaw (CWE-22/CWE-552) that may allow remote code execution. The record gives no affected version range, so scope cannot be confirmed from the data provided. With a CVSS 3.1 score of 9.8 and no privileges or user interaction required, this is a high-severity exposure for any internet-reachable deployment.

Impact

An unauthenticated remote attacker could traverse directories and potentially execute code on the affected host, gaining full control of confidentiality, integrity and availability per the CVSS vector.

Attack surface

Reachable over the network (AV:N) with no authentication (PR:N) and no user interaction (UI:N). The description does not specify the exact endpoint or service, so the precise entry point is not stated in the record.

Exploitation

Not listed in CISA KEV and no ransomware usage documented, but EPSS is 0.56287 (99th percentile), indicating a high predicted likelihood of exploitation. A public GitHub proof-of-concept reference exists, though the record does not confirm active exploitation.

What to do

• Apply the HPE vendor advisory fix for Insight Remote Support as the first action.
• Restrict network access to the Insight Remote Support service; do not expose it to untrusted networks.
• Validate and sanitize all file path inputs on any externally reachable interface.
• Monitor HPE advisories for updated affected version details and patch accordingly.
• Isolate the host from sensitive internal segments until patched.

Detection

• Alert on path traversal patterns (../, encoded variants) in requests to Insight Remote Support endpoints.
• Monitor for unexpected process creation or child processes spawned by the Insight Remote Support service.
• Review file access logs for reads or writes outside expected application directories.
• Watch for outbound connections from the host to unfamiliar destinations after suspicious requests.
