Availability: High

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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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 2026-10-26.

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 firmware upgrade: Organizations should monitor iND Co.,Ltd's official channels for patches addressing this vulnerability and apply updates promptly once available. 2. Access control hardening: Restrict administrative access to HL330-DLS devices to trusted personnel only, using strong authentication methods and network segmentation to limit exposure. 3. Network-level protections: Implement firewall rules and intrusion detection/prevention systems to monitor and block suspicious commands or traffic targeting the affected devices. 4. Privilege management: Minimize the number of users with high privilege levels on these devices to reduce the attack surface. 5. Device inventory and monitoring: Maintain an accurate inventory of all HL330-DLS devices and continuously monitor their behavior for anomalies indicative of exploitation attempts. 6. Incident response readiness: Prepare and test incident response plans specific to device compromise scenarios to enable rapid containment and recovery. 7. Vendor engagement: Engage with iND Co.,Ltd for detailed guidance, support, and early access to patches or mitigations. These steps go beyond generic advice by focusing on device-specific controls, privilege minimization, and proactive monitoring tailored to the HL330-DLS environment.

Description

Multiple products provided by iND Co.,Ltd contain an OS command injection vulnerability. If exploited, an arbitrary OS command may be executed and sensitive information may be obtained. As for the details of affected product names and versions, refer to the information under [Product Status].

Impact

For European organizations, exploitation of CVE-2025-53508 could lead to severe operational disruptions, data breaches, and potential lateral movement within networks. Organizations relying on HL330-DLS devices for communication or industrial control could face unauthorized disclosure of sensitive data, manipulation of device functions, or complete device takeover. This could impact sectors such as manufacturing, telecommunications, energy, and critical infrastructure, where such devices might be deployed. The high integrity and availability impact could result in downtime or malfunction of critical systems, affecting business continuity and safety. Additionally, compromised devices could be leveraged as entry points for broader attacks against corporate or national networks, increasing the risk of espionage or sabotage. The requirement for high privileges to exploit the vulnerability suggests that insider threats or attackers who have already gained some level of access pose the greatest risk, emphasizing the need for robust internal security controls.

Summary

CVE-2025-53508 is a high-severity OS command injection vulnerability affecting iND Co.,Ltd's HL330-DLS device, specifically for the MC7700 module. The vulnerability exists due to improper neutralization of special elements used in OS commands, allowing an attacker to inject arbitrary commands into the operating system. This flaw is present in firmware versions 1.03 and earlier. Exploitation of this vulnerability can lead to execution of arbitrary OS commands with the privileges of the affected device, potentially resulting in unauthorized access to sensitive information, system compromise, and disruption of device functionality. The vulnerability has a CVSS v3.0 base score of 7.2, indicating high severity, with the vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. This means the attack can be performed remotely over the network with low attack complexity but requires high privileges and no user interaction. The impact includes full confidentiality, integrity, and availability compromise of the affected device. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the critical nature of OS command injection flaws. The HL330-DLS device is likely used in specialized industrial or communication environments given the MC7700 module context, which may be embedded in critical infrastructure or enterprise systems. The lack of available patches at the time of publication necessitates immediate attention from users of affected firmware versions to mitigate potential exploitation risks.
