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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: 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 22 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 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.

AI-suggested

Apply official patches from Centreon as soon as they are released for versions 23.10.x, 24.04.x, and 24.10.x to remediate the vulnerability.
Until patches are available, restrict elevated user privileges strictly to trusted personnel and enforce the principle of least privilege to minimize potential attackers with high-level access.
Implement Web Application Firewalls (WAF) with robust XSS detection and filtering rules to block malicious payloads targeting the vulnerable modules.
Conduct regular audits of user accounts with elevated privileges and monitor for unusual activity within the Notification rules and Open tickets modules.
Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the Centreon web interface.
Educate administrators and users with elevated privileges about the risks of stored XSS and safe input handling practices.
Monitor Centreon Infra Monitoring logs for any suspicious input or access patterns indicative of attempted exploitation.
Consider isolating the monitoring interface within a segmented network zone to reduce exposure to external threats.

Description

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Centreon Infra Monitoring (Notification rules, Open tickets module) allows Stored XSS by users with elevated privileges.This issue affects Infra Monitoring: from 24.10.0 before 24.10.5, from 24.04.0 before 24.04.5, from 23.10.0 before 23.10.4.

Impact

For European organizations, the impact of CVE-2025-8460 can be significant, especially those in sectors relying heavily on Centreon Infra Monitoring for critical infrastructure and IT operations management. Successful exploitation could lead to unauthorized disclosure of sensitive monitoring data, session hijacking, and potential lateral movement within the network. This could undermine the integrity of monitoring data and delay detection of other security incidents. Confidentiality breaches could expose internal system configurations, alerting mechanisms, and operational statuses, which adversaries could leverage for targeted attacks. Given the elevated privileges required, insider threats or compromised privileged accounts pose the greatest risk. The vulnerability could also facilitate supply chain attacks if attackers gain persistent access to monitoring dashboards. The absence of known exploits in the wild suggests the window for proactive mitigation remains open, but the medium severity rating and critical role of the product in infrastructure monitoring necessitate urgent remediation to prevent escalation.

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
