Scope: Changed
Confidentiality: Low
Integrity: None
Availability: Low

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

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Mar 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 2026-10-26.

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

1. Apply patches and firmware updates from GE Vernova as soon as they become available to address the vulnerability directly. 2. Restrict network access to the management interfaces of N60 Multilin devices using network segmentation and access control lists (ACLs) to limit exposure to trusted hosts only. 3. Implement strict firewall rules that monitor and control port forwarding configurations and prevent unauthorized changes. 4. Deploy network intrusion detection and prevention systems (IDS/IPS) tuned to detect anomalous TCP forwarding or unusual connection patterns related to these devices. 5. Conduct regular configuration audits and integrity checks on N60 Multilin devices to detect unauthorized modifications. 6. Use network segmentation to isolate operational technology (OT) environments from corporate IT networks, reducing the attack surface. 7. Train operational staff to recognize signs of network anomalies and suspicious device behavior. 8. Establish incident response procedures specific to OT environments to quickly contain and remediate potential exploitation attempts.

Description

A CWE-15 "External Control of System or Configuration Setting" in GE Vernova UR IED family devices from version 7.0 up to 8.60 allows an attacker to provide input that establishes a TCP connection through a port forwarding. The lack of the IP address and port validation may allow the attacker to bypass firewall rules or to send malicious traffic in the network.

Impact

For European organizations, especially those in the energy, utilities, and industrial sectors, this vulnerability presents a risk of unauthorized network access and potential disruption of critical infrastructure operations. By exploiting this flaw, attackers could bypass firewall protections, enabling lateral movement within internal networks or injection of malicious traffic that could degrade device performance or availability. This could lead to partial denial of service or exposure of sensitive operational data, impacting confidentiality and availability. Given the strategic importance of energy infrastructure in Europe and the reliance on GE Vernova devices in many facilities, successful exploitation could have cascading effects on grid stability and service continuity. Additionally, the vulnerability could be leveraged as a foothold for more advanced attacks targeting industrial control systems. The medium severity rating reflects the balance between the ease of exploitation and the limited direct impact on integrity, but the potential for broader network compromise elevates the concern for European critical infrastructure operators.

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.

Because setting manipulation covers a diverse set of functions, any attempt at illustrating it will inevitably be incomplete. Rather than searching for a tight-knit relationship between the functions addressed in the setting manipulation category, take a step back and consider the sorts of system values that an…
Implementation · Architecture and Design
In general, do not allow user-provided or otherwise untrusted data to control sensitive values. The leverage that an attacker gains by controlling these values is not always immediately obvious, but do not underestimate the creativity of the attacker.
