Attack Vector: Network
Attack Complexity: Low

Confidentiality: High
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: 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 20 Aug 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.

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.

AI-suggested

1. Immediately restrict access to the router management interface by limiting it to trusted internal IP addresses or disabling remote management where possible. 2. Monitor network traffic for unusual or malformed requests targeting the /goform/getproductInfo endpoint to detect potential exploitation attempts. 3. Apply firmware updates from Tenda as soon as they are released to address this vulnerability. 4. If patches are not yet available, consider replacing affected devices with models from vendors with timely security updates. 5. Employ network segmentation to isolate routers from critical infrastructure and sensitive data environments. 6. Use intrusion detection/prevention systems (IDS/IPS) to identify and block suspicious packets targeting known vulnerable endpoints. 7. Educate users and administrators about the risks of exposing router management interfaces to untrusted networks.

Description

An information disclosure vulnerability exists in the /goform/getproductInfo functionality of Tenda AC6 V5.0 V02.03.01.110. Specially crafted network packets can lead to a disclosure of sensitive information. An attacker can send packets to trigger this vulnerability.

Impact

For European organizations, this vulnerability poses a significant risk of sensitive information leakage from affected Tenda AC6 routers. Disclosure of device-specific information can facilitate targeted attacks, including further exploitation of router vulnerabilities or lateral movement within networks. Small and medium enterprises or home office environments using these routers could be particularly vulnerable due to potentially weaker network segmentation and security controls. The confidentiality breach could expose network topology, firmware versions, or administrative details, enabling attackers to craft more effective attacks or gain unauthorized access. While the vulnerability does not directly affect integrity or availability, the information gained could lead to more severe compromises. Given the widespread use of Tenda routers in residential and small business markets across Europe, the potential impact includes privacy violations, unauthorized network access, and increased risk of subsequent attacks.
