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 14 Oct 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 2026-10-25.

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. Immediately implement network segmentation to isolate devices running the affected firmware from general IT networks and untrusted segments. 2. Employ network-level encryption such as VPNs or secure tunnels (e.g., IPsec) to protect traffic to and from the impacted devices until a firmware update is available. 3. Monitor network traffic for unencrypted credential transmissions and unusual access attempts to the Web-UI. 4. Restrict access to the device management interfaces using firewall rules and access control lists to limit exposure to trusted hosts only. 5. Engage with Murrelektronik for firmware updates or patches addressing this vulnerability and apply them promptly once released. 6. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect attempts to exploit cleartext credential transmission. 7. Educate operational technology personnel about the risks of unencrypted communications and enforce policies to avoid transmitting sensitive information in cleartext. 8. Where possible, replace or upgrade devices that do not support secure communication protocols.

Description

A cleartext transmission of sensitive information vulnerability in the affected products allows an unauthorized remote attacker to gain login credentials and access the Web-UI.

Impact

The primary impact of this vulnerability is the compromise of confidentiality, as attackers can capture login credentials and gain unauthorized access to the device's Web-UI. For European organizations, especially those in industrial automation, manufacturing, and critical infrastructure sectors, this could lead to unauthorized control or monitoring of operational technology systems. Although integrity and availability are not directly affected, unauthorized access could be leveraged to perform further malicious actions, including configuration changes or lateral movement within the network. The exposure of credentials over unencrypted channels increases the risk of espionage, sabotage, or disruption of industrial processes. Given the strategic importance of manufacturing and industrial control systems in Europe, exploitation could have significant operational and economic consequences. The absence of known exploits currently reduces immediate risk but does not diminish the urgency for mitigation, as attackers may develop exploits once the vulnerability details are widely known.

CWE-319Cleartext Transmission of Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
