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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: 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 30 Jan 2026
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 26 Oct 2026.

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 or the CVSS exploit maturity 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.

What to do

Upgrade ManageEngine to 128582.

AI-suggested

2) Restrict access to ManageEngine OpManager, NetFlow Analyzer, and OpUtils interfaces to trusted and authenticated users only, employing strong authentication mechanisms such as multi-factor authentication (MFA). 3) Conduct thorough input validation and output encoding on all user-supplied data within the Subnet Details feature to prevent injection of malicious scripts. 4) Implement Content Security Policy (CSP) headers to reduce the impact of potential XSS payloads by restricting script execution sources. 5) Regularly audit and review user activity logs for suspicious behavior indicative of exploitation attempts. 6) Educate users about the risks of interacting with unexpected or suspicious content within the management interfaces to reduce the likelihood of triggering malicious scripts. 7) Employ network segmentation to limit the exposure of management tools to only necessary network segments and users. 8) Use web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting ManageEngine products.

Description

Zohocorp ManageEngine OpManager, NetFlow Analyzer, and OpUtils versions prior to 128582 are affected by a stored cross-site scripting vulnerability in the Subnet Details.

Impact

For European organizations, the impact of CVE-2025-9226 is primarily on the confidentiality and integrity of data managed by the affected ManageEngine products, which are widely used for network and infrastructure monitoring. Successful exploitation could allow attackers to execute arbitrary scripts in the context of authenticated users, potentially leading to session hijacking, unauthorized configuration changes, or lateral movement within the network. This is particularly concerning for critical infrastructure providers, financial institutions, and large enterprises that rely on ManageEngine tools for operational visibility and network management. While availability is not directly impacted, the indirect consequences of compromised integrity and confidentiality could disrupt monitoring accuracy and incident response capabilities. The requirement for authenticated access and user interaction limits the attack surface but does not eliminate risk, especially in environments with weak access controls or insufficient user training. European organizations must consider the potential for targeted attacks leveraging this vulnerability to gain footholds in their networks or escalate privileges.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
