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

Immediately restrict access to the router's management interface by disabling remote administration and limiting access to trusted IP addresses or internal networks only.
Implement network segmentation to isolate vulnerable routers from critical systems and sensitive data.
Monitor network traffic for unusual patterns or attempts to exploit the curTime parameter, using intrusion detection/prevention systems with custom signatures if possible.
Regularly audit and update router configurations to disable unnecessary services and enforce strong authentication where available.
Encourage users to change default credentials and use strong, unique passwords for router access.
Maintain an inventory of affected devices within the organization to prioritize mitigation efforts.
Stay informed about vendor advisories and apply firmware updates promptly once patches become available.
Consider deploying network-level protections such as firewalls or gateway devices that can detect and block exploit attempts targeting this vulnerability.
Educate users about the risks of exposing network devices to the internet and promote best practices for home and small office network security.

Description

D-Link DIR600L Ax FW116WWb01 was discovered to contain a buffer overflow via the curTime parameter in the function formAdvNetwork.

Impact

For European organizations, the impact of this vulnerability could be significant, especially for small and medium enterprises (SMEs) and home office users relying on the D-Link DIR600L Ax router. Exploitation could lead to unauthorized remote code execution, allowing attackers to gain control over the router, intercept or manipulate network traffic, and pivot to internal networks. This compromises confidentiality, integrity, and availability of organizational data and services. Disruption of network connectivity could affect business operations, while unauthorized access could lead to data breaches or facilitate further attacks within the network. Given the widespread use of D-Link routers in Europe, particularly in residential and small business markets, the vulnerability poses a broad risk. The lack of known exploits currently provides a window for proactive defense, but the potential for rapid weaponization exists. Organizations with less mature network security practices or those exposing router management interfaces to the internet are at higher risk. The impact is exacerbated by the absence of patches, requiring organizations to rely on compensating controls.

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…
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.

Implement and perform bounds checking on input.
