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: 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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within 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

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

Until an official patch is released by Samsung, organizations should implement the following mitigations: 1) Restrict network access to MagicINFO 9 Server interfaces by applying strict firewall rules and network segmentation to limit exposure to trusted management networks only. 2) Monitor network traffic and server logs for unusual authentication attempts or access patterns indicative of exploitation attempts. 3) Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics tuned to detect suspicious activity targeting MagicINFO servers. 4) Change any default or known credentials related to MagicINFO deployments where possible and audit existing credentials for weaknesses. 5) Engage with Samsung support channels to obtain security advisories and patches promptly once available. 6) Consider deploying multi-factor authentication (MFA) on management interfaces if supported, to add an additional layer of defense. 7) Conduct regular security assessments and penetration testing focused on MagicINFO infrastructure to identify and remediate potential weaknesses.

Description

Use of Hard-coded Credentials vulnerability in Samsung Electronics MagicINFO 9 Server allows Authentication Bypass.This issue affects MagicINFO 9 Server: less than 21.1080.0.

Impact

The impact of CVE-2025-54455 is significant for organizations using Samsung MagicINFO 9 Server. Successful exploitation allows attackers to bypass authentication controls remotely, leading to unauthorized access to sensitive digital signage management systems. This can result in unauthorized content manipulation, leakage of confidential information, disruption of digital signage operations, and potential lateral movement within corporate networks. The compromise of MagicINFO servers could also damage organizational reputation, especially in sectors relying on digital signage for critical communications such as retail, transportation, healthcare, and corporate environments. Given the widespread use of MagicINFO in various industries globally, the vulnerability poses a substantial risk to operational integrity and data confidentiality. The absence of required privileges and user interaction lowers the barrier for attackers, increasing the likelihood of exploitation and potential widespread impact.

CWE-798Use of Hard-coded Credentials (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product contains hard-coded credentials, such as a password or cryptographic key.
Architecture and Design
For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320).
Architecture and Design
For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a "first login" mode that requires the user to enter a unique strong password or key.
Architecture and Design
If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
