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: 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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Sep 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 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

1. Immediate firmware upgrade: Organizations should monitor Baicells' official channels for patches or firmware updates addressing CVE-2025-55052 and apply them promptly once available. 2. Network segmentation: Restrict access to management interfaces of affected Baicells devices to trusted network segments and limit exposure to the internet or untrusted networks. 3. Access control hardening: Enforce strict authentication and authorization policies to minimize the number of users with privileges sufficient to exploit this vulnerability. 4. Monitor and audit: Implement continuous monitoring and logging of access to Baicells devices to detect unusual or unauthorized access attempts. 5. Use VPN or secure tunnels: Where remote management is necessary, ensure connections are secured via VPNs or encrypted tunnels to reduce the risk of interception or unauthorized access. 6. Incident response readiness: Prepare to investigate and respond to potential information disclosure incidents, including verifying device configurations and reviewing logs for signs of exploitation. 7. Vendor engagement: Engage with Baicells support to obtain guidance, timeline for patches, and best practices specific to these devices. 8. Limit privilege exposure: Review and minimize privileges assigned to users and services interacting with these devices to reduce the attack surface.

Description

CWE-200 Exposure of Sensitive Information to an Unauthorized Actor

Impact

For European organizations, especially those utilizing Baicells NEUTRINO and NOVA series equipment for wireless broadband or private LTE/5G networks, this vulnerability poses a risk of sensitive information leakage. Such exposure could lead to unauthorized disclosure of network configuration, credentials, or operational data, potentially enabling attackers to map network topology, identify weaknesses, or prepare for more severe attacks such as network intrusion or service disruption. Organizations in sectors relying on private wireless networks—such as utilities, transportation, manufacturing, and critical infrastructure—may be particularly impacted. The confidentiality breach could undermine trust in network security and compliance with data protection regulations like GDPR if personal or sensitive data is indirectly exposed. Although the vulnerability does not directly affect integrity or availability, the information disclosure could be a stepping stone for more damaging attacks. The requirement for some privilege to exploit the vulnerability limits the risk to insider threats or attackers who have gained limited access, but the network exposure vector means that attackers who compromise a less secure segment could leverage this vulnerability to escalate their knowledge and foothold.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
