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: 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within 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

Exploitation evidence

CVE published 9 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

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

European organizations should immediately upgrade the Tenda TDSEE App to version 1.7.15 or later to remediate this vulnerability. Beyond patching, organizations should implement multi-factor authentication (MFA) for account access to reduce the risk of unauthorized access even if password reset mechanisms are targeted. Monitoring and alerting on unusual password reset activity or repeated authentication attempts can help detect exploitation attempts early. Network segmentation should be enforced to limit the exposure of devices managed by the app. Additionally, organizations should review and tighten password reset policies, including rate limiting and CAPTCHA integration, to prevent automated brute force attacks. User education about phishing and social engineering risks related to password resets can further reduce risk. Finally, maintaining an inventory of all Tenda devices and apps in use will help prioritize patch deployment and risk assessment.

Description

A vulnerability was found in Tenda TDSEE App up to 1.7.12. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /app/ConfirmSmsCode of the component Password Reset Confirmation Code Handler. The manipulation leads to improper restriction of excessive authentication attempts. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 1.7.15 is able to address this issue. It is recommended to upgrade the affected component.

Impact

For European organizations using Tenda TDSEE App, this vulnerability poses a moderate risk primarily to user account security and confidentiality. The improper restriction of authentication attempts could enable attackers to perform brute force or enumeration attacks on password reset confirmation codes, potentially leading to unauthorized account access. This could result in exposure of sensitive user data or unauthorized control over network devices managed via the app, especially if the app is used for managing routers or IoT devices. While the direct impact on system integrity and availability is minimal, compromised accounts could be leveraged for further attacks or lateral movement within organizational networks. The medium severity and high attack complexity reduce the likelihood of widespread exploitation, but organizations with high reliance on Tenda devices or apps for network management should be vigilant. Additionally, the remote exploitability without user interaction increases the attack surface. The impact is more pronounced in sectors with critical infrastructure or sensitive data, such as telecommunications, government, and enterprises using Tenda networking equipment.
