    What is affected, what to do

    Execution with Unnecessary Privileges vulnerability in multiple services of Mitsubishi Electric GENESIS64 versions 10.97.3 and prior, Mitsubishi Electric ICONICS Suite versions 10.97.3 and prior, Mitsubishi Electric MobileHMI versions 10.97.3 and prior, Mitsubishi Electric Hyper Historian versions 10.97.3 and prior, Mitsubishi Electric AnalytiX versions 10.97.3 and prior, Mitsubishi Electric IoTWorX version 10.95, Mitsubishi Electric GENESIS32 all versions, Mitsubishi Electric BizViz all versions, Mitsubishi Electric MC Works64 all versions, Mitsubishi Electric GENESIS versions 11.00, Mitsubishi Electric Iconics Digital Solutions GENESIS64 versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions ICONICS Suite versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions MobileHMI versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions Hyper Historian versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions AnalytiX versions 10.97.3 and prior, Mitsubishi Electric Iconics Digital Solutions IoTWorX version 10.95, Mitsubishi Electric Iconics Digital Solutions GENESIS32 all versions, Mitsubishi Electric Iconics Digital Solutions BizViz all versions, and Mitsubishi Electric Iconics Digital Solutions GENESIS versions 11.00 allows a local authenticated attacker to make an unauthorized write to arbitrary files, by creating a symbolic link from a file used as a write destination by the services of the affected products to a target file. This could allow the attacker to destroy the file on a PC with the affected products installed, resulting in a denial-of-service (DoS) condition on the PC if the destroyed file is necessary for the operation of the PC.

    Medium
    Priority (0–325)

    The priority score is a consolidated metric that condenses several individual signals into a single, action-guiding ranking: technical severity (CVSS), exploitation likelihood (EPSS), known-exploited status (KEV) and the context of the affected asset. The aim is to answer the only truly important question in vulnerability management: what first?

    43.03 Methodology
    Exploit maturity

    An exploit is code or a technique that specifically uses a concrete vulnerability to force unintended behaviour — such as executing code or escalating privileges. It is the tool that turns a theoretical flaw into a practical attack.

    XIEM Effective CVSS

    XIEM® is the tiered managed-security operating model from NEOSEC and a registered trademark of NEOSEC GmbH. It extends classic SIEM — the central collection, normalisation and correlation of security-relevant events — with endpoint forensics, network visibility and deception technology, and consolidates them into three building tiers: Sentry, Orchestrate and Command.

    6.5 Methodology
    CVSS v3

    CVSS is the globally established, open standard for assessing the technical severity of a vulnerability on a scale from 0 to 10. It describes how easily a flaw can be exploited and what damage it can cause — but not how likely its actual exploitation is. CVSS and the complementary EPSS deliberately answer different questions.

    6.5
    EPSS score

    The EPSS score is the absolute model output for an individual vulnerability: the estimated probability of real-world exploitation within the next 30 days, expressed as a value between 0 and 1 (i.e. 0 % to 100 %). A score of 0.42 means „the model estimates a 42 % chance of real-world exploitation within 30 days“.

    Read in glossary
    0.2 %
    Low — model estimates < 1% exploitation likelihood.
    EPSS percentile

    The EPSS percentile is the relative position of a vulnerability within all EPSS-scored CVEs, expressed as a value between 0 and 1. A percentile of 0.90 means „this CVE has a higher EPSS score than 90 % of all other scored CVEs“. Unlike the EPSS score, it is not a probability — but a positioning within a ranking.

    13.9
    Elevated — this CVE ranks above at least 10% of all CVEs scored today.
    KEV status

    The KEV catalogue is a list maintained by the US authority CISA of vulnerabilities for which active exploitation in the wild has been confirmed. It answers not the question „how severe?“ but „is it already being attacked?“ — thereby sharply prioritising patching.

    CWE

    CWE is a catalogue of typical weakness types in software and hardware — such as flawed input validation, unsafe memory handling or poor authentication. Where a CVE names a concrete vulnerability in a concrete product, a CWE describes the underlying class of defect.

    Detection rules

    No NEOSEC detection rule is available for this vulnerability yet.

    Classification under NIS2 and CRA

    Rule-based classification from exploitation status and severity. It does not replace a case-by-case assessment.

    NIS2

    NIS2 is EU Directive (EU) 2022/2555 to raise the level of cybersecurity across the Union. It substantially broadens obligations compared with the first NIS directive: more sectors, mandatory risk management, staged reporting duties and personal accountability of senior management.

    Read in glossary
    Handle the vulnerability in regular vulnerability handling under Art. 21(2)(e) NIS2.
    CRA

    The CRA is EU Regulation (EU) 2024/2847 setting horizontal cybersecurity requirements for „products with digital elements“ — from industrial controllers and software to connected consumer devices. For the first time manufacturers must ensure security across the entire product lifecycle, handle vulnerabilities and provide security updates.

    Read in glossary
    From 11.12.2027, Annex I Part II CRA requires manufacturers of affected products with digital elements to handle vulnerabilities without delay and provide security updates.
    ISO/IEC 27001

    ISO/IEC 27001 is the internationally leading standard for an information security management system (ISMS). It describes a risk-based, process-oriented framework to systematically plan, implement, review and improve information security.
