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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Jul 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
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 Samsung Electronics MagicINFO 9 Server to 21.1080.0.

AI-suggested

Immediate upgrade: Organizations should upgrade MagicINFO 9 Server to version 21.1080.0 or later, where this vulnerability is addressed.
Network segmentation: Isolate MagicINFO servers from general user networks and restrict access to trusted administrators only, minimizing exposure to external threats.
Access controls: Implement strict firewall rules and VPN requirements to limit remote access to the MagicINFO server.
Monitoring and logging: Enable detailed logging on MagicINFO servers and monitor for unusual authentication attempts or access patterns indicative of bypass attempts.
Incident response readiness: Prepare response plans specifically for digital signage infrastructure compromise, including rapid content restoration and communication protocols.
Vendor engagement: Maintain contact with Samsung for timely updates and patches, and subscribe to security advisories related to MagicINFO products.
Security testing: Conduct penetration testing and vulnerability assessments focused on MagicINFO deployments to identify potential exploitation paths and validate mitigations.

Description

Improper Authentication vulnerability in Samsung Electronics MagicINFO 9 Server allows Authentication Bypass.This issue affects MagicINFO 9 Server: less than 21.1080.0.

Impact

For European organizations, the impact of this vulnerability can be significant, especially for sectors relying on digital signage for critical communications such as transportation hubs, retail chains, corporate campuses, and public institutions. Unauthorized access could allow attackers to alter displayed content, potentially spreading misinformation or malicious messages. Additionally, disruption of signage services could affect customer experience and operational workflows. Since MagicINFO servers often integrate with internal networks, exploitation could serve as a foothold for further attacks, threatening broader network security. The confidentiality impact, while rated low, could expose sensitive configuration or operational data. Integrity and availability impacts could disrupt business continuity and damage brand reputation. Organizations in Europe with large deployments of Samsung MagicINFO 9 Server should consider this vulnerability a priority due to the potential for both direct and indirect consequences on their digital communication channels and network security posture.
