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.

Detectable: 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 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

AI-suggested

Apply patches promptly once Centreon releases updates for versions 25.10.2, 24.10.15, and 24.04.19 or later that address this vulnerability.
Restrict administrative access to the Centreon Infra Monitoring platform using network segmentation, VPNs, and strict access control policies to limit exposure to high-privilege accounts.
Implement strong authentication mechanisms such as multi-factor authentication (MFA) for all administrative users to reduce the risk of credential compromise.
Deploy Web Application Firewalls (WAFs) with rules to detect and block common XSS payloads targeting the Centreon interface.
Conduct regular security audits and code reviews of custom configurations or plugins that interact with the ACL menu to detect any unsafe input handling.
Monitor logs and user activity for unusual behavior indicative of attempted or successful exploitation.
Educate administrators about the risks of stored XSS and safe input handling practices when configuring ACL menus or other web interface elements.
Consider isolating the monitoring platform from general user networks to reduce the attack surface.

Description

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Centreon Infra Monitoring (Administration ACL menu configuration modules) allows Stored XSS to users with high privileges. This issue affects Infra Monitoring: from 25.10.0 before 25.10.2, from 24.10.0 before 24.10.15, from 24.04.0 before 24.04.19.

Impact

For European organizations, the impact of CVE-2025-13056 can be significant, especially those using Centreon Infra Monitoring for critical infrastructure and network management. Successful exploitation could lead to unauthorized disclosure of sensitive information accessible through the monitoring platform, such as configuration details, user data, or operational metrics. Since the vulnerability requires high privileges, the attacker would likely be an insider or someone who has already compromised an administrative account, thus potentially escalating the impact of an existing breach. Confidentiality breaches could facilitate further attacks, including lateral movement or targeted espionage. The vulnerability does not directly affect system integrity or availability, so service disruption is unlikely. However, the trustworthiness of monitoring data and administrative interfaces could be undermined, impacting incident response and operational decision-making. European sectors such as energy, telecommunications, finance, and government agencies that rely on Centreon for infrastructure monitoring are particularly at risk. The medium severity score reflects the balance between the required privileges and the potential confidentiality impact.

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.
