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: 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.
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 24 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 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 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-level controls: Restrict access to the web management interface of DCN DCME-720 devices to trusted management networks only, using firewall rules or network segmentation to prevent exposure to untrusted networks or the internet. 2. Implement strict access control lists (ACLs) to limit which IP addresses can reach the vulnerable endpoint. 3. Monitor network traffic and device logs for unusual or suspicious requests targeting the /usr/local/www/function/audit/newstatistics/ip_block.php path or attempts to inject commands via the 'ip' parameter. 4. If possible, disable the vulnerable web management interface or restrict its functionality until a vendor patch is available. 5. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection attempts against this device. 6. Consider deploying web application firewalls (WAF) in front of management interfaces to filter malicious input. 7. Maintain an inventory of all DCN devices and verify firmware versions; avoid upgrading to the vulnerable version 9.1.5.11 or roll back if feasible. 8. Engage with DCN or authorized support channels to seek official patches or mitigations. 9. Prepare incident response plans to quickly isolate and remediate compromised devices. 10. Educate network administrators about this vulnerability and the importance of securing management interfaces.

Description

A vulnerability was found in DCN DCME-720 9.1.5.11. This affects an unknown function of the file /usr/local/www/function/audit/newstatistics/ip_block.php of the component Web Management Backend. Performing manipulation of the argument ip results in os command injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used. Other products might be affected as well. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using DCN DCME-720 devices, this vulnerability poses a significant risk to network infrastructure security. The ability to remotely execute OS commands without authentication can lead to full compromise of the affected device, which is likely used for network management or communication purposes. Compromise could result in unauthorized access to internal networks, interception or manipulation of network traffic, disruption of services, or use of the device as a pivot point for further attacks. Given the device's role, critical infrastructure sectors such as telecommunications, government agencies, and enterprises relying on DCN equipment could face operational disruptions and data breaches. The lack of vendor response and patches increases the window of exposure, and public exploit availability raises the likelihood of active exploitation attempts. European organizations must consider the potential for espionage, sabotage, or ransomware attacks leveraging this vulnerability, especially in environments where these devices are integral to network operations.
