Attack Vector: Network
Attack Complexity: Low

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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 3 Jun 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.

AI-suggested

1. Immediate network segmentation: Isolate affected D-Link DI-500WF-WT devices from critical network segments to limit potential lateral movement in case of compromise. 2. Access control: Restrict management interface access to trusted IP addresses only, using firewall rules or router ACLs, to reduce exposure of the vulnerable endpoint. 3. Disable or restrict access to the /msp_info.htm endpoint if possible, or implement web application firewall (WAF) rules to detect and block suspicious command injection patterns targeting the 'cmd' parameter. 4. Monitor network traffic and router logs for unusual commands or access patterns indicative of exploitation attempts. 5. Engage with D-Link support channels to obtain firmware updates or patches as soon as they become available, and plan for timely deployment. 6. Consider replacing affected devices with models that have confirmed security updates if patching is delayed. 7. Implement network intrusion detection/prevention systems (IDS/IPS) with signatures targeting command injection attempts on router management interfaces. 8. Educate network administrators on the risks and signs of exploitation to ensure rapid incident response.

Description

A vulnerability has been found in D-Link DI-500WF-WT up to 20250511 and classified as critical. Affected by this vulnerability is the function sub_456DE8 of the file /msp_info.htm?flag=cmd of the component /usr/sbin/jhttpd. The manipulation of the argument cmd leads to command injection. The attack can be launched remotely.

Impact

For European organizations, this vulnerability presents a tangible threat to network infrastructure security, especially for those relying on D-Link DI-500WF-WT routers in their environments. Successful exploitation could lead to unauthorized command execution, enabling attackers to compromise router configurations, intercept sensitive data, or launch further attacks within the network. This could result in data breaches, service disruptions, and potential lateral movement within corporate networks. Given that routers serve as critical gateways for internet access, exploitation could also facilitate man-in-the-middle attacks or network traffic manipulation. The medium severity rating suggests that while exploitation requires some privilege level, the absence of user interaction and remote attack vector increases the risk. Organizations in sectors with stringent data protection requirements (e.g., finance, healthcare, government) could face regulatory and reputational damage if such vulnerabilities are exploited. Additionally, the lack of available patches necessitates immediate attention to alternative mitigation strategies to protect network integrity and confidentiality.
