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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Mar 2025
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

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

European organizations should implement strict validation and sanitization of HTTP Host headers within TRMTracker and any associated web infrastructure to prevent injection of malicious values. Employing web application firewalls (WAFs) with rules targeting Host header anomalies can provide an additional layer of defense. Configure cache-control headers to prevent caching of responses that depend on the Host header or implement cache partitioning to avoid poisoning. Monitor HTTP traffic logs for unusual Host header values and suspicious user access patterns. Engage with Hitachi Energy to obtain patches or updates as they become available and apply them promptly. Conduct security awareness training to reduce the risk of successful user interaction-based exploitation. Additionally, perform regular security assessments and penetration testing focusing on HTTP header handling to identify and remediate similar vulnerabilities proactively.

Description

A Host Header Injection vulnerability in TRMTracker application may allow an attacker by modifying the host header value in an HTTP request to leverage multiple attack vectors, including defacing the site content through web-cache poisoning.

Impact

For European organizations, especially those in the energy sector using Hitachi Energy's TRMTracker, this vulnerability poses a risk of unauthorized content manipulation and potential exposure of sensitive information. Web-cache poisoning can lead to users receiving malicious or altered content, undermining trust and potentially enabling further attacks such as phishing or malware delivery. The confidentiality and integrity of data processed or displayed by TRMTracker could be compromised, affecting operational decision-making and reporting. Given the critical nature of energy infrastructure in Europe, exploitation could disrupt business processes or damage reputations. Although availability is not directly impacted, the indirect consequences of compromised data integrity could lead to operational inefficiencies or regulatory scrutiny. The lack of known exploits reduces immediate risk but should not lead to complacency, as attackers may develop exploits once the vulnerability becomes widely known.
