CVE-2025-13658

Longwatch Devices Arbitrary Code Execution Vulnerability

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

A vulnerability in Longwatch devices allows unauthenticated HTTP GET requests to execute arbitrary code via an exposed endpoint, leading to SYSTEM-level privileges. This affects monitoring systems and bypasses code signing controls. The concern is to confirm device presence and assess potential exposure.

CVE advisoryCRITICAL

CVE-2025-13510

Iskra iHUB Lite Unauthenticated Web Interface Access

Halo Surface Signal: 5 out of 5 — more likely to be public-facing.

The Iskra iHUB and iHUB Lite smart metering gateways have a critical vulnerability where their web management interface is accessible without authentication. This allows unauthenticated users to access and modify critical device settings, potentially disrupting metering services.

CVE advisoryCRITICAL

CVE-2025-13828

Composer Package Installation Privilege Escalation

Halo Surface Signal: 3 out of 5 — possibly public-facing.

A non-privileged user can install arbitrary packages, potentially executing malicious code and escalating privileges on systems that use composer for package management, even if composer-based updates are disabled. This could allow a low-privileged user to obtain higher privileges on the platform.

CVE advisoryCRITICAL

CVE-2025-59703

Entrust nShield Physical Tamper F14 Attack Vulnerability

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

Entrust nShield hardware security modules are vulnerable to a physical tamper attack that allows an attacker with direct access to bypass tamper evidence and access internal components. This could potentially compromise cryptographic operations and sensitive data if the device is reachable by a physically proximate att

CVE advisoryCRITICAL

CVE-2025-59693

Entrust nShield Chassis Debug Access Vulnerability F02.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

A vulnerability in Entrust nShield devices allows a physically proximate attacker to bypass tamper labels, open the chassis, and access the JTAG connector to gain debug access and escalate privileges. This could compromise sensitive hardware functions and lead to unauthorized system control.

CVE advisoryCRITICAL

CVE-2025-41744

Sprecher Automation SPRECON-E Default Keys Expose Communications

Halo Surface Signal: 2 out of 5 — less likely to be public-facing.

Sprecher Automation SPRECON-E devices use default cryptographic keys, allowing unprivileged remote attackers to access all encrypted communications, compromising data confidentiality and integrity. This vulnerability is relevant to organizations using these devices in critical infrastructure, as it could expose sensiti

CVE advisoryCRITICAL

CVE-2025-41742

Sprecher SPRECON-E devices default keys enable remote data manipulation and access

Halo Surface Signal: 2 out of 5 — less likely to be public-facing.

Sprecher Automation SPRECON devices contain a critical vulnerability due to default cryptographic keys, allowing unauthorized remote attackers to read, modify, or write project data and access devices via remote maintenance. This could lead to the compromise of sensitive operational data and device control. The main co
