Attack Vector: Physical
Attack Complexity: Low
Privileges Required: Low
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 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 2026-10-26.

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.

What to do

AI-suggested

To mitigate this vulnerability, European organizations should: 1) Ensure all Samsung Galaxy Tablets are updated promptly with the SMR July 2025 Release 1 or later, which is expected to address this improper authorization issue. 2) Restrict physical and local access to devices, especially in shared environments, by enforcing strict device usage policies and employing device management solutions that limit secondary user capabilities. 3) Disable or limit multi-user functionality on tablets where feasible to reduce the attack surface. 4) Employ Mobile Device Management (MDM) solutions to enforce security policies and monitor device usage. 5) Educate users about the risks of sharing devices and the importance of safeguarding credentials. 6) Consider network segmentation and additional Wi-Fi security measures (e.g., WPA3, certificate-based authentication) to reduce the impact if credentials are compromised. 7) Monitor network access logs for unusual activity that could indicate misuse of compromised Wi-Fi credentials.

Description

Improper authorization in accessing saved Wi-Fi password for Galaxy Tablet prior to SMR Jul-2025 Release 1 allows secondary users to access owner's saved Wi-Fi password.

Impact

For European organizations, especially those using Samsung Galaxy Tablets in shared or multi-user environments (e.g., corporate tablets, kiosks, or shared devices), this vulnerability poses a risk of unauthorized disclosure of Wi-Fi credentials. Attackers or unauthorized secondary users gaining access to saved Wi-Fi passwords could leverage this information to infiltrate corporate or private networks, potentially bypassing network access controls. This could facilitate further attacks such as man-in-the-middle, unauthorized network access, or lateral movement within the organization's infrastructure. The confidentiality breach could expose sensitive network configurations and credentials, undermining network security. Although the vulnerability requires local access and some user interaction, in environments where devices are shared or physically accessible to multiple users, the risk is elevated. The impact is more pronounced in sectors with strict data protection requirements and high reliance on secure wireless networks, such as finance, healthcare, and government institutions across Europe.

CWE-285Improper Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records.
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.
