Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
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: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system 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 vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the vulnerable system.
Vulnerable system availability: High: There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the Vulnerable System; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the Vulnerable System (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).
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 2026-10-26.

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 check for and apply any firmware updates released by Tenda addressing CVE-2026-1610. 2. 3. Restrict remote management access to the router by disabling WAN-side administration or limiting access to trusted IP addresses. 4. Implement network segmentation to isolate the router and critical network assets, reducing the potential impact of compromise. 5. Monitor network traffic for unusual Telnet connection attempts or other suspicious activity targeting the router. 6. Replace affected devices with models from vendors with a stronger security track record if patching or disabling Telnet is not feasible. 7. Educate users and administrators about the risks of hard-coded credentials and the importance of disabling legacy services like Telnet. 8. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting this vulnerability. 9. Regularly audit router configurations to ensure no unauthorized changes have been made. 10. Maintain an incident response plan to quickly address any detected compromise related to this vulnerability.

Description

A vulnerability was found in Tenda AX12 Pro V2 16.03.49.24_cn. Affected by this issue is some unknown functionality of the component Telnet Service. Performing a manipulation results in hard-coded credentials. The attack is possible to be carried out remotely. A high degree of complexity is needed for the attack. The exploitation is known to be difficult. The exploit has been made public and could be used.

Impact

The impact of CVE-2026-1610 is substantial for organizations and individuals using the Tenda AX12 Pro V2 router with the affected firmware. Successful exploitation can lead to full compromise of the device, allowing attackers to intercept, manipulate, or disrupt network traffic, potentially leading to data breaches, unauthorized network access, and lateral movement within internal networks. The confidentiality of sensitive information passing through the router is at risk, as is the integrity of network configurations and the availability of network services. For businesses, this could mean exposure of proprietary data, disruption of operations, and damage to reputation. For home users, it could result in privacy violations and unauthorized use of internet resources. The difficulty of exploitation reduces the immediate risk but does not eliminate it, especially as exploit code is publicly available. The lack of authentication and user interaction requirements means attackers can attempt exploitation remotely without alerting users. The absence of patches increases the window of vulnerability, making proactive mitigation critical. Overall, the vulnerability poses a critical threat to network security wherever the affected device and firmware are deployed.

Summary

CVE-2026-1610 identifies a critical security vulnerability in the Tenda AX12 Pro V2 router firmware version 16.03.49.24_cn. The issue arises from hard-coded credentials embedded within the Telnet service component of the device. These hard-coded credentials enable an attacker to remotely access the device without requiring authentication or user interaction. The vulnerability affects confidentiality, integrity, and availability by potentially allowing attackers to execute arbitrary commands, alter configurations, or disrupt network services. Exploitation complexity is high, indicating that a skilled attacker is required to leverage this flaw effectively. Although no active exploits have been observed in the wild, the public disclosure of exploit code increases the likelihood of future attacks. The Telnet service, often enabled by default or left active inadvertently, broadens the attack surface. The vulnerability is particularly concerning because it does not require prior authentication or user interaction, allowing remote attackers to gain privileged access. The CVSS 4.0 base score of 9.2 reflects the critical nature of this vulnerability, with attack vector being network-based and no privileges or user interaction needed. The scope is limited to the affected firmware version and product, but given the popularity of Tenda routers in various global markets, the potential impact is significant.
