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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
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 impacted component 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 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 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.

What to do

AI-suggested

Organizations should immediately audit their network to identify any Tenda AC10U devices running the affected firmware version 15.03.06.49_multi_TDE01. 2) Enforce strong, unique administrative credentials to prevent unauthorized authentication. 3) Disable remote management features if not required, especially WAN-side access. 4) Monitor network traffic for unusual activity indicative of exploitation attempts. 5) Consider replacing affected devices with alternative models from vendors with active security support. 6) If possible, implement network-level intrusion detection/prevention systems (IDS/IPS) to detect exploitation attempts targeting this vulnerability. 7) Maintain up-to-date inventory and documentation of network devices to enable rapid response. 8) Educate users and administrators about the risks of default credentials and the importance of firmware updates. Given the vendor's lack of response, organizations should also engage with Tenda support channels and monitor for any future patches or advisories.

Description

A vulnerability was found in Tenda AC10U 15.03.06.49_multi_TDE01. It has been rated as critical. Affected by this issue is the function fromNatStaticSetting. The manipulation of the argument page leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. VDB-252134 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, especially small businesses and home offices relying on Tenda AC10U routers, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized control of network infrastructure, enabling attackers to intercept sensitive communications, inject malicious traffic, or pivot into internal networks. This could compromise confidentiality and integrity of data and disrupt availability of network services. Given the medium CVSS score, the impact is somewhat mitigated by the requirement for authentication, but in environments where default or weak credentials are used, the risk escalates. Additionally, the lack of vendor response and patch availability increases exposure time. Critical infrastructure operators or enterprises using these routers in branch offices may face operational disruptions or data breaches. The vulnerability also poses a risk to privacy compliance under GDPR if personal data is intercepted or manipulated. The potential for denial of service could affect business continuity, especially for organizations with limited IT support to quickly remediate or replace affected devices.

Summary

CVE-2024-0929 is a stack-based buffer overflow vulnerability identified in the Tenda AC10U router, specifically affecting firmware version 15.03.06.49_multi_TDE01. The vulnerability resides in the function fromNatStaticSetting, where improper handling and manipulation of the 'page' argument leads to a stack-based buffer overflow condition. This type of vulnerability occurs when data exceeding the buffer's boundary is written to the stack, potentially overwriting adjacent memory and control data such as return addresses. Exploiting this flaw could allow an attacker to execute arbitrary code, cause a denial of service (DoS) by crashing the device, or alter the device's behavior. The vulnerability is remotely exploitable over the network without requiring user interaction, but it does require high privileges (PR:H), indicating that the attacker must have some form of authenticated access to the device's management interface or network segment. The CVSS v3.1 base score is 4.7 (medium severity), reflecting the requirement for authentication and the limited confidentiality, integrity, and availability impacts. Although no known exploits have been observed in the wild, the public disclosure of the vulnerability and technical details increases the risk of exploitation by attackers. The affected product, Tenda AC10U, is a consumer-grade wireless router commonly used in home and small office environments. The vulnerability's exploitation could allow attackers to gain control over the router, intercept or manipulate network traffic, or disrupt network connectivity.

Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #14
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…
