Confidentiality: None
Integrity: None
Availability: High

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Jun 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

1. Implement strict access controls and monitoring: Since exploitation requires authenticated access, enforce multi-factor authentication (MFA) for all users accessing the PI Data Archive systems. 2. Conduct regular credential audits and promptly revoke access for inactive or unnecessary accounts to reduce insider threat risks. 3. Monitor system logs and alerts for unusual shutdown events or exceptions within the PI Data Archive subsystems to detect potential exploitation attempts early. 4. Segment the network to isolate PI Data Archive servers from general IT networks, limiting exposure to compromised credentials. 5. Develop and test incident response plans specifically for PI Data Archive availability disruptions to minimize downtime. 6. Engage with AVEVA support channels to obtain patches or workarounds as soon as they become available, and prioritize timely deployment. 7. Consider deploying application-layer firewalls or intrusion detection systems tuned to detect anomalous authenticated user behavior targeting PI Data Archive services. 8. Train operational staff to recognize and report suspicious activity related to PI Data Archive access and subsystem behavior. These measures go beyond generic advice by focusing on the authenticated nature of the exploit, emphasizing insider threat mitigation, and operational continuity planning specific to PI Data Archive environments.

Description

AVEVA PI Data Archive products are vulnerable to an uncaught exception that, if exploited, could allow an authenticated user to shut down certain necessary PI Data Archive subsystems, resulting in a denial of service.

Impact

For European organizations, especially those in critical infrastructure sectors such as energy, utilities, manufacturing, and transportation, this vulnerability poses a significant risk to operational continuity. The AVEVA PI System is widely deployed across Europe in industries that depend on real-time data for process optimization and safety monitoring. A denial of service attack exploiting this vulnerability could lead to interruptions in data availability, impacting decision-making, automated control systems, and regulatory compliance reporting. While it does not compromise data confidentiality or integrity, the loss of availability can cause operational delays, safety risks, and financial losses. Organizations with distributed or remote OT environments may face challenges in rapid recovery, increasing downtime. Additionally, the requirement for authenticated access means that insider threats or attackers who have gained legitimate credentials could leverage this vulnerability to disrupt operations. The absence of known exploits currently reduces immediate risk, but the medium severity score and ease of exploitation (low complexity) indicate that threat actors could develop exploits in the near future, especially targeting European industrial sectors with high AVEVA PI adoption.
