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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Active: Successful exploitation of this vulnerability requires a targeted user to perform specific, conscious interactions with the vulnerable system and the attacker’s payload, or the user’s interactions would actively subvert protection mechanisms which would lead to exploitation of the vulnerability.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within 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.

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 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

To mitigate CVE-2023-53961, organizations should implement multiple layers of defense: 1) Apply any available vendor patches or updates as soon as they are released. 2) If patches are not yet available, restrict access to the administrative interfaces of SOUND4 products by network segmentation, VPNs, or IP whitelisting to limit exposure. 3) Implement CSRF protections such as anti-CSRF tokens in the web interface, if configurable, or request the vendor to provide such protections. 4) Enforce strict session management policies, including short session timeouts and re-authentication for sensitive operations. 5) Educate users with access to these systems about the risks of phishing and visiting untrusted websites while logged into administrative interfaces. 6) Monitor logs for unusual administrative actions or HTTP requests originating from unexpected sources. 7) Consider deploying web application firewalls (WAFs) that can detect and block CSRF attack patterns. 8) Regularly audit user privileges to ensure only necessary personnel have administrative access. These steps collectively reduce the attack surface and limit the potential for exploitation until a full patch is available.

Description

SOUND4 IMPACT/FIRST/PULSE/Eco v2.x contains a cross-site request forgery vulnerability that allows attackers to perform administrative actions without user consent. Attackers can craft malicious web pages that submit HTTP requests to the radio processing interface, triggering unintended administrative operations when a logged-in user visits the page.

Impact

For European organizations, this vulnerability poses a risk primarily to broadcast and radio infrastructure that utilizes SOUND4 Impact, Pulse, or First products. Unauthorized administrative actions could lead to misconfiguration, service disruption, or potential denial of service in critical communication systems. This could affect public broadcasters, emergency communication services, and private radio networks, potentially impacting information dissemination and operational continuity. The ease of exploitation—requiring only that a logged-in user visits a malicious page—raises the risk of targeted attacks or phishing campaigns against personnel with access to these systems. While confidentiality impact is low, integrity and availability concerns could have cascading effects on dependent services. The lack of known exploits currently reduces immediate risk, but the medium severity and network accessibility mean organizations should act proactively. The impact is heightened in environments where administrative interfaces are exposed or where user session management is weak. Failure to mitigate could result in unauthorized control over critical broadcast parameters, undermining trust and operational reliability.
