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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 6 Aug 2025
Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 or the CVSS exploit maturity 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 Electrolink transmitters should immediately conduct an inventory to identify affected devices and versions. Until patches or official fixes are released, organizations should restrict network access to the web management interfaces, ideally isolating these devices on dedicated management VLANs with strict firewall rules permitting access only from trusted administrative hosts. Implement network segmentation to separate broadcast management systems from general IT networks. Employ strong authentication mechanisms, such as VPNs or multi-factor authentication, for remote access to management interfaces. Monitor network traffic and logs for unusual access patterns to the /FrameSetCore.html endpoint. Engage with Electrolink or authorized vendors to obtain security advisories and patches as they become available. Additionally, consider deploying intrusion detection systems tailored to detect anomalous activity targeting broadcast management systems. Regularly update and audit device firmware and configurations to ensure compliance with security best practices.

Description

Electrolink FM/DAB/TV Transmitter Web Management System Unauthorized access vulnerability via the /FrameSetCore.html endpoint in Electrolink 500W, 1kW, 2kW Medium DAB Transmitter Web v01.09, v01.08, v01.07, and Display v1.4, v1.2.

Impact

For European organizations, especially broadcasters and media companies relying on Electrolink transmitters for FM, DAB, and TV services, this vulnerability poses significant risks. Unauthorized access to transmitter management systems could allow attackers to disrupt broadcast services, causing denial of service to listeners and viewers, which can have regulatory, reputational, and financial consequences. Manipulation of broadcast parameters could lead to interference with other spectrum users or violation of licensing agreements. Additionally, attackers could potentially use the compromised devices as pivot points within the network, threatening broader operational technology (OT) and IT infrastructure. Given the critical nature of broadcast infrastructure in Europe for public communication, emergency alerts, and media dissemination, exploitation of this vulnerability could impact public safety and information dissemination. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially if attackers develop exploits post-disclosure.
