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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: 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.

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.

AI-suggested

Immediately update all affected Honeywell S35 cameras to the vendor-recommended versions released in August 2025 to patch the authorization bypass vulnerability.
Implement strict network segmentation to isolate security cameras from general corporate networks, limiting attacker lateral movement if a device is compromised.
Enforce strong access controls and monitoring on camera management interfaces, including multi-factor authentication where supported.
Regularly audit camera firmware versions and configurations to ensure compliance with security policies.
Deploy network intrusion detection systems (NIDS) to monitor for anomalous traffic patterns targeting camera devices.
Limit exposure of camera management ports to the internet or untrusted networks.
Educate security teams on this specific vulnerability to recognize potential exploitation attempts.
Maintain an incident response plan that includes compromised physical security devices to quickly isolate and remediate affected assets.

Description

CVE-2025-12351 is an authorization bypass vulnerability in Honeywell S35 series cameras, allowing attackers with low privileges to escalate to admin-level access by exploiting a user-controlled key. This flaw affects multiple camera models including 3M, 5M, 8M, Pinhole, and Kit variants. The vulnerability does not require user interaction but demands network access and has a medium CVSS score of 6.8. Exploitation could lead to full administrative control over the affected cameras, compromising confidentiality and integrity of video feeds and device configurations. Honeywell recommends updating to specific versions released in August 2025 to mitigate this issue. European organizations using these cameras in critical infrastructure or security-sensitive environments are at risk. Countries with high adoption of Honeywell security products and strategic critical infrastructure deployments are more likely to be targeted. Immediate patching and network segmentation are critical to reduce exposure.

Impact

For European organizations, this vulnerability poses a significant risk to physical security and operational integrity. Compromise of Honeywell S35 cameras could lead to unauthorized surveillance, tampering with video evidence, or disabling security monitoring, which is critical in sectors such as transportation, energy, government facilities, and corporate campuses. The ability to escalate privileges to admin level increases the risk of attackers pivoting into broader network environments, potentially leading to data breaches or disruption of critical services. Confidentiality and integrity of surveillance data are directly impacted, undermining trust in security infrastructure. Given the medium CVSS score and the high attack complexity, exploitation might be limited to skilled attackers with network access, but the consequences remain severe. Organizations in Europe with extensive deployments of Honeywell cameras in sensitive locations must prioritize remediation to avoid potential espionage, sabotage, or compliance violations under regulations like GDPR.

Summary

CVE-2025-12351 identifies an authorization bypass vulnerability in Honeywell S35 series cameras, including 3M, 5M, 8M, Pinhole, and Kit models. The vulnerability arises from improper authorization checks related to a user-controlled key, classified under CWE-639 (Authorization Bypass Through User-Controlled Key) and CWE-668 (Exposure of Resource to Wrong Sphere). An attacker with low privileges (PR:L) can exploit this flaw remotely (AV:N) without user interaction (UI:N) but with high attack complexity (AC:H). Successful exploitation allows privilege escalation to administrative functions, granting control over camera settings, video streams, and potentially enabling further network reconnaissance or lateral movement. The CVSS v3.1 score is 6.8 (medium severity), reflecting high confidentiality and integrity impact but no availability impact. Honeywell has released patches in August 2025 for various S35 camera models: Pinhole/Kit (version 2025.08.28), AI Fisheye & Dual Sensor/Micro Dome/Full Color Eyeball & Bullet (2025.08.22), and Thermal Camera (2025.08.26). No known exploits are currently reported in the wild, but the vulnerability's nature makes it a significant risk for environments relying on these cameras for physical security. The vulnerability's exploitation could undermine surveillance integrity, allowing attackers to disable or manipulate video feeds or gain footholds in secured networks.

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Architecture and Design · Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
