Integrity: None
Availability: None

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: 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.

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

AI-suggested

Given the absence of an official patch, European organizations and users should take immediate proactive steps to mitigate risk. First, restrict network access to the router's management interface by implementing network segmentation and firewall rules that limit access to trusted IP addresses only. Disable remote management features if not required, to reduce exposure to external attackers. Regularly monitor network traffic and router logs for unusual activity that could indicate exploitation attempts. Where possible, replace or upgrade affected Tenda AC10 devices to newer firmware versions once patches become available or consider alternative hardware with stronger security track records. Employ network intrusion detection systems (NIDS) to detect anomalous behavior related to router compromise. Educate users about the risks of using default credentials and enforce strong, unique passwords for router administration. Finally, maintain an active vulnerability management program to track updates from Tenda and promptly apply security patches when released.

Description

Incorrect access control in the endpoint /goform/ate of Tenda AC10 v4.0 firmware v16.03.10.09_multi_TDE01 allows attackers to escalate privileges or access sensitive components via a crafted request.

Impact

For European organizations, the impact of this vulnerability could be substantial, especially for those relying on Tenda AC10 routers in their network infrastructure. Compromise of these routers could lead to unauthorized access to internal networks, interception of sensitive communications, and disruption of network availability. In environments where these routers are used for critical business operations or as part of a larger network security perimeter, attackers exploiting this vulnerability could gain persistent access, potentially leading to data breaches, intellectual property theft, or lateral movement to other systems. Small and medium enterprises (SMEs) and home office setups, which often use consumer-grade routers like the Tenda AC10, may be particularly vulnerable due to less stringent network security controls. Additionally, the absence of known exploits currently does not preclude future active exploitation, especially as threat actors often target widely deployed consumer devices to establish botnets or launch further attacks. The vulnerability could also undermine trust in network infrastructure and lead to compliance issues under European data protection regulations if sensitive data is exposed.

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
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.
