Why You Should Care

Mobile applications that interface with Industrial Control Systems (ICS)—such as for device monitoring or configuration—can be powerful but risky. When these apps have vulnerabilities, attackers might gain a foothold into critical infrastructure systems. That makes prompt attention, patching, and secure design essential.

Most Recent Mobile‑App ICS Advisory: ICSA‑25‑219‑06 – Dreame Technology (Dreamehome & MOVAhome Mobile Apps)

  • Release Date: August 7, 2025
  • Link: Official CISA Advisory ICSA‑25‑219‑06
  • Vulnerability: Improper Certificate Validation (accepts self-signed certs) — allows proxy/MITM attacks
  • Assigned: CVE‑2025‑8393
    • CVSS v3.1: 7.3 (AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N)
    • CVSS v4: 8.5 (AV:A/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N)
  • Impact: Credential/session token interception on untrusted networks.
  • Mitigation (from CISA):
    • Isolate ICS networks behind firewalls
    • Minimize public or internet exposure
    • Use VPNs with noted precautions

Complete List of ICS Mobile‑App‑Related Advisories (Ordered by Severity – CVSS v4)

Advisory Code Vendor / App Date CVSS v4 Score* Platforms Primary Issues Link
ICSA-25-219-06 Dreame Technology – Dreamehome & MOVAhome Aug 7, 2025 8.5 iOS, Android Improper certificate validation (CWE-295) – MITM risk Link
ICSA-25-072-12 Sungrow – iSolarCloud Android App WiNet Firmware Mar 13, 2025 N/A Android Improper certificate validation, insecure cryptography, authorization bypass, hard-coded credentials, buffer overflow Link
ICSA-25-196-01 Hitachi Energy – Asset Suite AnyWhere for Inventory (AWI) Jul 15, 2025 N/A Android Plaintext password storage, out-of-bounds write, improper input validation Link
ICSA-24-067-01 Chirp Systems – Chirp Access May 2, 2024 N/A iOS, Android Hard-coded password enabling Bluetooth beacon manipulation Link
ICSA-18-081-01 Siemens – SIMATIC WinCC OA UI Mobile App Mar 22, 2018 N/A iOS, Android Improper access control – potential access to cached project data via malicious server Link
ICSA-18-128-03 Siemens – Siveillance VMS Video Mobile App May 8, 2018 N/A iOS, Android Improper certificate validation – risk of interception of encrypted app-server communications Link

*CVSS v4 score shown if published by CISA; otherwise N/A.

*CISA lists CVSS v3.0 of 6.4; CVSS v4 not provided—but still the second-highest among mobile-app advisories.

Generalized Vulnerability Patterns

  • Improper Certificate Validation is most common—present in both mobile-app advisories (Dreame, IGSS Mobile).
  • Plaintext credentials storage appears in IGSS Mobile.
  • Other ICS advisories often involve software infrastructure or firmware—not mobile apps.

Developer & User Recommendations

For Developers:

  • Enforce proper TLS certificate validation or pin certificates where appropriate.
  • Avoid storing credentials in plaintext—use secure storage mechanisms.
  • Conduct regular third-party audits and testing, especially for mobile communication components.

For Users:

  • Update apps promptly when vendors publish fixes.
  • Prefer secure networks, avoid managing ICS devices over public Wi-Fi.
  • Limit app access to only what’s necessary—use network segmentation and least privilege.

Visual Summaries

Consider including:

  • A severity-focused bar chart ranking mobile-app advisories by CVSS v4.
  • A vulnerability-category graphic (e.g., certificate issues vs plaintext storage).

Final Thoughts & Call to Action

ICS-adjacent mobile apps introduce fresh attack surfaces to critical systems. While only two such exposures are documented so far, they highlight recurring issues that must be addressed at scale. Whether you’re developing or managing these applications, prioritizing secure design and deployment can make the difference between safe operations and systemic risk.
