Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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

To mitigate CVE-2024-58320, organizations should first verify if their Kentico Xperience installations are affected and monitor for any vendor patches or updates. In the absence of an official patch, restrict access to the authentication endpoints exposing hostname details by implementing IP whitelisting or VPN-only access. Employ network segmentation to isolate the administration interface from public-facing networks, reducing exposure. Enable detailed logging and monitoring on authentication endpoints to detect unusual access patterns or reconnaissance attempts. Consider deploying web application firewalls (WAFs) with custom rules to block requests attempting to access sensitive configuration endpoints. Educate system administrators about the risk of information disclosure and encourage regular security audits of CMS configurations. Finally, maintain an incident response plan to quickly address any exploitation attempts.

Description

CVE-2024-58320 is an information disclosure vulnerability in Kentico Xperience that allows unauthenticated public users to access sensitive hostname details of the administration interface during authentication. This exposure can reveal internal network configuration information, potentially aiding attackers in further reconnaissance or targeted attacks. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. Exploitation requires no authentication or user interaction and can be performed remotely over the network. Although no known exploits are currently reported in the wild, the leak of internal hostnames can facilitate lateral movement or social engineering attacks. European organizations using Kentico Xperience should prioritize patching or mitigating this issue to protect internal infrastructure details. Countries with significant Kentico deployments and critical infrastructure relying on this CMS are at higher risk. Mitigation includes restricting access to authentication endpoints, implementing network segmentation, and monitoring for suspicious access patterns.

Impact

For European organizations, the exposure of sensitive hostname information can have several adverse effects. It can facilitate attackers in understanding internal network architecture, making subsequent attacks such as credential theft, lateral movement, or targeted phishing campaigns more effective. Organizations in sectors with high regulatory requirements (e.g., finance, healthcare, government) may face compliance risks if internal infrastructure details are leaked. Additionally, attackers could use this information to bypass perimeter defenses or craft social engineering attacks against system administrators. While the vulnerability does not directly compromise system integrity or availability, the information disclosure can be a critical enabler for more severe attacks. The impact is heightened for organizations with complex internal networks or those relying heavily on Kentico Xperience for critical web services.

Summary

CVE-2024-58320 is an information disclosure vulnerability identified in Kentico Xperience, a widely used content management system. The flaw allows unauthenticated public users to retrieve sensitive hostname information related to the administration interface during the authentication process. Specifically, a public endpoint inadvertently exposes confidential hostname configuration details, which are intended to remain internal. This exposure can reveal internal network topology, hostnames, and potentially other metadata that attackers can leverage for reconnaissance and to craft more effective attacks, such as targeted phishing or lateral movement within a compromised network. The vulnerability does not require any privileges or user interaction, making it easily exploitable remotely over the network. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) reflects that the attack vector is network-based with low complexity, no authentication, and no user interaction required, but the impact is limited to confidentiality (information disclosure) without affecting integrity or availability. No patches or known exploits are currently reported, but the exposure of internal hostnames can significantly aid attackers in mapping the target environment. Kentico Xperience customers should assess their exposure and implement mitigations promptly.
