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: 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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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

To mitigate CVE-2025-54766 effectively, European organizations should: 1) Immediately audit and restrict access controls on XorMon-NG API endpoints, ensuring that only authorized administrator accounts can access privileged functions. 2) Implement network segmentation and firewall rules to limit access to management interfaces and APIs to trusted administrative networks. 3) Monitor API usage logs for anomalous access patterns, particularly any attempts by read-only users to access export functions. 4) Enforce the principle of least privilege by reviewing user roles and permissions within the XorMon-NG application, removing unnecessary access rights. 5) Engage with the vendor (Xorux) to obtain patches or updates addressing this vulnerability as soon as they become available. 6) Consider deploying Web Application Firewalls (WAFs) or API gateways that can enforce additional access controls and detect unauthorized API calls. 7) Educate administrators and security teams about this vulnerability to ensure prompt detection and response to suspicious activity. These steps go beyond generic advice by focusing on access control hardening, monitoring, and vendor coordination specific to the XorMon-NG environment.

Description

An API endpoint that should be limited to web application administrators is hidden from, but accessible by, lower-level read only web application users. The endpoint can be used to export the appliance configuration, exposing sensitive information.

Impact

For European organizations, the exposure of appliance configuration data through this vulnerability could lead to significant confidentiality breaches. Sensitive configuration details might include network topology, authentication credentials, or security settings, which attackers could leverage to escalate privileges, move laterally within networks, or disrupt operations indirectly. Organizations in sectors such as critical infrastructure, telecommunications, finance, and government are particularly at risk due to the potential for targeted attacks exploiting this information. Although the vulnerability does not directly impact system integrity or availability, the information disclosure could serve as a stepping stone for more severe attacks. The medium severity rating suggests that while the immediate risk is moderate, the potential for exploitation in complex attack chains exists. European entities using XorMon-NG appliances should assess their exposure, especially if these devices are accessible from less trusted networks or if read-only users have broad access privileges.

CWE-648Incorrect Use of Privileged APIs (opens in a new tab)
Base weaknessLikelihood of exploit: Low
The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.
Implementation
Before calling privileged APIs, always ensure that the assumptions made by the privileged code hold true prior to making the call.
Architecture and Design
Know architecture and implementation weaknesses of the privileged APIs and make sure to account for these weaknesses before calling the privileged APIs to ensure that they can be called safely.
Implementation
If privileged APIs make certain assumptions about data, context or state validity that are passed by the caller, the calling code must ensure that these assumptions have been validated prior to making the call.
