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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Since no official patches or firmware updates are currently available for CVE-2024-41465, organizations should implement the following specific mitigations: 1) Restrict network access to the management interface of Tenda FH1201 routers by implementing firewall rules that limit access to trusted IP addresses only. 2) Disable remote management features if not required, especially access to the 'ip/goform/setcfm' endpoint or similar administrative interfaces. 3) Monitor network traffic for unusual or malformed HTTP requests targeting the vulnerable endpoint, using intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect attempts to exploit the 'funcpara1' parameter. 4) Segment and isolate vulnerable devices from critical network segments to minimize the impact of potential denial of service. 5) Maintain up-to-date asset inventories to identify all Tenda FH1201 devices and prioritize their protection. 6) Engage with Tenda support channels to obtain information on forthcoming patches and apply updates promptly once available. 7) Consider deploying network-level rate limiting or anomaly detection to identify and block suspicious traffic patterns targeting the router’s management interfaces.

Description

Tenda FH1201 v1.2.0.14 was discovered to contain a stack-based buffer overflow vulnerability via the funcpara1 parameter at ip/goform/setcfm.

Impact

The primary impact of CVE-2024-41465 is denial of service, which can disrupt network connectivity for affected organizations. Since the vulnerability allows remote exploitation without authentication, attackers can target exposed Tenda FH1201 routers to cause service outages. This can affect both enterprise and consumer environments relying on these devices for internet access or internal network routing. Prolonged or repeated exploitation could lead to significant downtime, impacting business operations, communications, and potentially critical services dependent on network availability. Although the vulnerability does not compromise data confidentiality or integrity, the loss of availability can indirectly affect organizational productivity and security monitoring capabilities. In environments where Tenda FH1201 devices are deployed at scale, coordinated attacks could cause widespread network disruptions. The absence of known exploits in the wild currently limits immediate risk, but the vulnerability’s characteristics make it a likely candidate for future exploitation attempts.

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…
