Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system 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 Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system 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 Vulnerable System 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 Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 31 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

European organizations using the D-Link DI-500WF router should immediately assess their deployment of the affected firmware version 14.04.10A1T. Until an official patch is released, organizations should implement the following mitigations: 1) Restrict administrative access to the router interface to trusted networks and IP addresses only, using firewall rules and network segmentation to limit exposure. 2) Enforce strong authentication mechanisms and change default credentials to prevent unauthorized access that could lead to privilege escalation. 3) Monitor router logs and network traffic for unusual activity indicative of exploitation attempts, such as unexpected command execution or configuration changes. 4) Disable remote management features if not required, reducing the attack surface. 5) Consider deploying network intrusion detection/prevention systems (IDS/IPS) to detect exploitation attempts targeting this vulnerability. 6) Plan for a timely firmware upgrade once D-Link releases a patch addressing CVE-2025-9745. 7) Educate IT staff about the vulnerability and ensure incident response plans include steps for router compromise scenarios. These targeted mitigations go beyond generic advice by focusing on access control, monitoring, and preparation for patching specific to this vulnerability and device.

Description

A security vulnerability has been detected in D-Link DI-500WF 14.04.10A1T. The impacted element is an unknown function of the file /version_upgrade.asp of the component jhttpd. The manipulation of the argument path leads to os command injection. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used.

Impact

For European organizations, this vulnerability poses a moderate risk to network infrastructure security. The D-Link DI-500WF is a consumer and small business router; if deployed in enterprise or critical environments, exploitation could lead to unauthorized command execution, potentially disrupting network services or enabling lateral movement within the network. The requirement for high privileges reduces the likelihood of remote exploitation by unauthenticated attackers, but insider threats or compromised credentials could be leveraged to exploit this vulnerability. Disruption of router functionality could impact availability of internet connectivity, affecting business operations. Additionally, compromised routers could be used as entry points for further attacks or for launching attacks against other targets. Given the interconnected nature of European networks and reliance on secure network infrastructure, exploitation could have cascading effects, especially in sectors with critical infrastructure or sensitive data. The absence of known exploits in the wild currently limits immediate risk but does not eliminate the threat, especially as public disclosure may encourage attackers to develop exploits.
