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. Immediately restrict WAN-side access to the router's management interfaces by implementing firewall rules or disabling remote management features to prevent unauthorized external access. 2. Segment the network to isolate the router management interface from general user traffic and untrusted networks. 3. Monitor network traffic for unusual or malformed requests targeting the WAN setup wizard endpoints, which may indicate exploitation attempts. 4. Deploy network intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect buffer overflow attempts against D-Link routers. 5. Encourage users and administrators to upgrade firmware promptly once an official patch is released by D-Link; meanwhile, consider temporary replacement of vulnerable devices if feasible. 6. For organizations relying on these routers, implement redundant internet connections or failover mechanisms to maintain connectivity during potential outages. 7. Educate IT staff and users about the risks of exposing router management interfaces to the internet and enforce strong network security policies. 8. Engage with D-Link support channels to obtain status updates on patch availability and coordinate vulnerability disclosure responses.

Description

D-Link DIR600L Ax FW116WWb01 was discovered to contain a buffer overflow via the curTime parameter in the function formSetWAN_Wizard7.

Impact

For European organizations, the primary impact of CVE-2025-60547 is on network availability. The affected D-Link DIR600L Ax routers are typically deployed in small office/home office (SOHO) environments, which are common in SMEs and remote work setups across Europe. A successful exploit could cause router crashes or reboots, leading to temporary loss of internet connectivity and disruption of business operations. While the vulnerability does not compromise data confidentiality or integrity directly, the resulting denial of service could hinder critical communications, remote access, and cloud service usage. Organizations with limited IT support or lacking redundant internet connections are particularly vulnerable. Additionally, the exploitation of such vulnerabilities could be leveraged as part of larger attacks, such as network reconnaissance or lateral movement, if combined with other weaknesses. The lack of authentication and user interaction requirements increases the risk of automated exploitation attempts from the internet. Given the widespread use of D-Link routers in European households and small businesses, the potential scope of impact is significant, especially in countries with high D-Link market share.

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…
