Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should implement strict access controls and physical security measures to limit local access to systems storing GT Designer3 project files. Encrypting project files or storing them on encrypted volumes can reduce the risk of credential disclosure. Regular audits and monitoring of access to engineering workstations and project files should be conducted to detect unauthorized access. Network segmentation should isolate engineering and HMI programming environments from broader corporate networks to reduce attack surface. Until official patches are released, consider using virtual desktop infrastructure (VDI) or hardened environments for HMI programming to limit credential exposure. Educate staff about the risks of local credential exposure and enforce strong endpoint security policies. Additionally, organizations should engage with Mitsubishi Electric for updates and apply patches promptly once available.

Description

Cleartext Storage of Sensitive Information vulnerability in Mitsubishi Electric GT Designer3 Version1 (GOT2000) all versions and Mitsubishi Electric GT Designer3 Version1 (GOT1000) all versions allows a local unauthenticated attacker to obtain plaintext credentials from the project file for GT Designer3. This could allow the attacker to operate illegally GOT2000 series or GOT1000 series by using the obtained credentials.

Impact

For European organizations, especially those in manufacturing, energy, and critical infrastructure sectors that rely on Mitsubishi Electric's GT Designer3 software and GOT series HMIs, this vulnerability poses a significant confidentiality risk. Unauthorized access to plaintext credentials could allow attackers to manipulate industrial control systems, potentially leading to operational disruptions or safety incidents. Although the attack requires local access and has high complexity, insider threats or attackers who gain physical or network access to engineering workstations could exploit this vulnerability. The lack of integrity and availability impact limits the scope to unauthorized information disclosure and potential unauthorized control commands. However, given the strategic importance of industrial automation in Europe, exploitation could have cascading effects on production lines and critical services. The absence of patches increases exposure time, necessitating immediate compensating controls.

Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
Implementation · System Configuration · Operation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
Implementation · System Configuration · Operation
In some systems/environments such as cloud, the use of "double encryption" (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
