Integer Overflow Leading to Buffer Overflow in Network Proxy Component

Publication date: 2026-09-15

Last updated on: 2026-09-28

Assigner: Hewlett Packard Enterprise (HPE)

Description

A vulnerability exists in the proxy packet processing logic of the affected component where it improperly processes malformed or truncated input. An unauthenticated remote attacker could exploit this vulnerability by providing specially crafted input that triggers an integer overflow. Successful exploitation could result in a buffer overflow, potentially leading to remote code execution or denial-of-service.

Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Attack-Flow Graph

Executive Summary

This vulnerability involves improper handling of malformed or truncated input in the proxy packet processing logic. An attacker can exploit it by sending specially crafted input that causes an integer overflow, leading to a buffer overflow. This may allow remote code execution or denial-of-service attacks.

Detection Guidance

This vulnerability involves improper processing of malformed input leading to integer overflow and potential remote code execution. Detection requires monitoring for unusual network traffic patterns or crashes in the affected proxy component. Check logs for segmentation faults or buffer overflow errors in the proxy service. Use network traffic analyzers like Wireshark to inspect for malformed packets targeting the proxy. Ensure the proxy service is running the latest patched version.

Impact Analysis

If exploited, this vulnerability could allow an unauthenticated remote attacker to execute arbitrary code on the affected system or cause a denial-of-service condition. This could lead to unauthorized access, data breaches, or system downtime.

Compliance Impact

This vulnerability could lead to remote code execution or denial-of-service, which may result in unauthorized access to sensitive data. Such breaches could violate GDPR's data protection requirements or HIPAA's safeguards for protected health information, potentially leading to legal penalties and compliance failures.

Mitigation Strategies

Apply vendor-provided patches or updates for the affected component immediately. Monitor network traffic for malformed packets and implement input validation to block truncated or specially crafted input. Restrict access to the vulnerable service if possible.
