Threat metrics

Exploit Maturity: POC

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

Attack Vector: Adjacent: The vulnerable system is bound to a protocol stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared proximity (e.g., Bluetooth, NFC, or IEEE 802.11) or logical network (e.g., local IP subnet), or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN within an administrative network zone).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system 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 Vulnerable System 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 Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

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 2026-10-25.

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.

AI-suggested

To mitigate this vulnerability, European organizations should implement strict network segmentation to isolate TOZED ZLT M30S devices from untrusted or general user segments, limiting access to the local network where these devices reside. Access controls should be enforced to restrict who can send HTTP POST requests to the device's web interface, ideally allowing only trusted administrators or management systems. Monitoring network traffic for suspicious POST requests containing 'goformId=REBOOT_DEVICE' can provide early detection of exploitation attempts. If possible, disable or restrict the web interface access to management VLANs or via secure management channels such as VPNs. Organizations should also consider replacing affected devices with alternative hardware from vendors with active security support if firmware updates or patches remain unavailable. Regular network device inventory and firmware version audits will help identify vulnerable devices. Finally, educating internal users about the risks of local network attacks and maintaining strong endpoint security can reduce the risk of insider or malware-driven exploitation.

Description

CVE-2025-14105 is a medium-severity denial of service vulnerability affecting TOZED ZLT M30S and ZLT M30S PRO devices running firmware versions 1.47 and 3.09.06. The flaw exists in the web interface component, specifically in the /reqproc/proc_post function, where manipulation of the 'goformId' argument with the input 'REBOOT_DEVICE' can cause the device to become unavailable. Exploitation requires local network access, does not require authentication or user interaction, and can be performed remotely within the LAN. The vendor has not responded to disclosure attempts, and no patches are currently available. Although no known exploits are in the wild, the vulnerability has been publicly disclosed and could be leveraged to disrupt network availability. European organizations using these devices in their local networks may face service interruptions impacting operational continuity. Mitigation involves network segmentation, restricting local network access to trusted users, monitoring for suspicious POST requests targeting 'goformId', and considering device replacement or firmware updates if available.

Impact

For European organizations, the primary impact is disruption of network availability due to forced device reboots or crashes, potentially causing downtime in local network segments. This can affect business continuity, especially in environments where TOZED ZLT M30S devices serve as critical network infrastructure components such as in small to medium enterprises, branch offices, or industrial control systems. The requirement for local network access limits remote exploitation but raises concerns about insider threats or malware propagation within internal networks. Unavailability of these devices could interrupt internet access, intranet services, or connectivity to operational technology systems, leading to productivity losses and potential safety risks in industrial settings. The absence of vendor patches prolongs exposure, increasing the window for exploitation. Additionally, the public disclosure of the vulnerability and exploit details may encourage attackers to target vulnerable networks, particularly in sectors with less mature network segmentation and monitoring practices.

Summary

CVE-2025-14105 identifies a denial of service (DoS) vulnerability in the TOZED ZLT M30S and ZLT M30S PRO routers, specifically affecting firmware versions 1.47 and 3.09.06. The vulnerability resides in the web interface component, within the /reqproc/proc_post handler. An attacker can send a crafted HTTP POST request manipulating the 'goformId' parameter with the value 'REBOOT_DEVICE', triggering a reboot or crash condition that results in denial of service. The attack vector is limited to the local network (AV:A), requiring no privileges (PR:N), no authentication (AT:N), and no user interaction (UI:N). The vulnerability impacts availability (VA:L) but does not affect confidentiality or integrity. The vendor was notified but has not issued a patch or response, leaving devices exposed. Although exploitation requires local network access, the publicly disclosed exploit details increase the risk of attacks by insiders or compromised hosts within the LAN. The lack of authentication on the web interface exacerbates the risk. The CVSS 4.0 score of 5.3 reflects a medium severity, balancing the limited attack surface with the ease of exploitation and impact on device availability. No known exploits are currently active in the wild, but the vulnerability could be leveraged to disrupt network operations, especially in environments relying on these devices for critical connectivity.
