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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; 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 impacted component (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).

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.

What to do

AI-suggested

1. Immediate mitigation should include isolating affected Tenda G3 routers from untrusted networks or restricting access to the router's management interfaces using firewall rules or network segmentation to reduce exposure. 2. Monitor network traffic for unusual or malformed requests targeting the staticRouteGateway parameter or related router management endpoints. 3. Regularly check for firmware updates from Tenda addressing this vulnerability and apply patches promptly once available. 4. 5. Implement network redundancy where feasible to minimize impact of router outages, such as secondary internet connections or failover devices. 6. Educate IT staff and users about the risks of using outdated or unsupported network devices and encourage proactive device lifecycle management. 7. Employ intrusion detection or prevention systems capable of detecting anomalous requests that may exploit this vulnerability. 8. Maintain up-to-date backups of router configurations to enable rapid recovery or replacement in case of device failure.

Description

Tenda G3 v3.0br_V15.11.0.17 was discovered to contain a stack overflow in the staticRouteGateway parameter in the formSetStaticRoute function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.

Impact

For European organizations, especially small businesses and home offices relying on Tenda G3 routers, this vulnerability poses a significant risk to network availability. A successful exploitation would result in denial of service, causing loss of internet connectivity and disruption of business operations dependent on continuous network access. This could impact remote work, VoIP communications, cloud services access, and other critical online functions. While the vulnerability does not directly compromise data confidentiality or integrity, the resulting downtime could lead to productivity losses and potential financial impact. Additionally, in sectors where network availability is critical, such as healthcare, finance, or public services, even short outages could have cascading effects. The lack of authentication and user interaction requirements makes exploitation easier for attackers, increasing the likelihood of opportunistic attacks. European organizations with limited IT support or outdated network equipment are particularly vulnerable. Furthermore, if attackers combine this DoS vulnerability with other attack vectors, they could use it as a distraction or part of a multi-stage attack. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially once exploit code becomes publicly available.

CWE-121Stack-based Buffer Overflow (opens in a new tab)
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…
