HPE Networking ALE Flaws Let Hackers Bypass Security Controls and Compromise Systems

Hewlett Packard Enterprise has released security updates for HPE Networking Analytics and Location Engine, or ALE, after finding multiple flaws that could let attackers bypass security controls, access sensitive data, and take over vulnerable systems.

The issues affect ALE version 5.0.0.0 and earlier. HPE fixed the vulnerabilities in ALE 5.1.0.0 and urges customers to upgrade as soon as possible. The advisory, tracked as HPESBNW05137 rev.1, was released on September 22, 2026.

The most serious flaws are CVE-2026-76708 and CVE-2026-76709, both rated critical with a CVSS score of 9.8. They can be exploited remotely without authentication or user interaction, making them especially dangerous for exposed or poorly segmented ALE deployments.

CVE-2026-76708 stems from default, hard-coded credentials used by several administrative and system accounts. An attacker could try known credentials to log in to the ALE management interface and the underlying operating system. If successful, the attacker could gain unauthorized access and potentially fully compromise the appliance.

CVE-2026-76709 affects an internal administrative component. The flaw allows an unauthenticated remote attacker to write arbitrary files to the ALE file system with elevated privileges.

Arbitrary file-write weaknesses can be highly damaging because attackers may use them to alter system files, plant malicious code, change configurations, or pave the way to full device takeover.

HPE Networking ALE Vulnerabilities

HPE also disclosed several high-severity flaws that expand the attack surface. CVE-2026-76710 can expose sensitive site hierarchy, network infrastructure, and client-device information through crafted requests to internal management endpoints.

Such information could help an attacker map a target environment before launching additional attacks. CVE-2026-76711 allows unauthenticated attackers to inject unauthorized data by sending crafted input during socket connections.

CVE-2026-76712 could lead to unauthorized access, information disclosure, security-control bypass, or denial of service through manipulated input or intercepted network traffic.

Two other issues require authentication but can still result in serious consequences. CVE-2026-76713 affects ALE maintenance restore functionality and may grant an authenticated attacker unauthorized root-level file system access.

CVE-2026-76714 allows authenticated remote users to execute arbitrary commands as root on the underlying host, enabling complete system compromise.

The remaining flaws include CVE-2026-76715, a man-in-the-middle issue that could allow root-level remote code execution, and CVE-2026-76716, which can enable unauthorized access or denial of service. CVE-2026-76717 may disclose sensitive user information, including password hashes, through a vulnerable API endpoint.

HPE said its internal security research team discovered the vulnerabilities. The company said it was not aware of public exploit code or active exploitation when it published the advisory. However, the wide range of issues and the presence of two critical unauthenticated bugs make rapid remediation important.

Organizations using ALE should upgrade to version 5.1.0.0. Until patching is complete, HPE recommends restricting command-line and web management interfaces to a dedicated Layer 2 segment or VLAN.

Administrators should also enforce Layer 3 firewall controls, limit access to trusted management hosts, and enable logging and accounting controls to monitor user actions and resource use. Older ALE versions that are no longer supported should be treated as potentially affected.
