CVE-2025-56019: Medium Vulnerability in Agasta Easytouch+

An insecure permission vulnerability exists in the Agasta Easytouch+ version 9.3.97. This vulnerability allows unauthorized mobile applications to connect via Bluetooth Low Energy (BLE) without authentication. Once an unauthorized connection is established, legitimate applications are unable to connect, causing a denial of service. The attack requires proximity to the device, making it exploitable from an adjacent network location.

The severity of this vulnerability is classified as medium with a CVSS score of 6.5. This score reflects the potential high availability impact, as legitimate users may be locked out of services. Organizations must be aware of this vulnerability, as the consequences of exploitation could lead to significant disruptions in service.

As of now, there is a known exploit for this vulnerability, and organizations should prioritize patching immediately to mitigate any risks related to unauthorized access via BLE connections.

Given the nature of the exploit requiring physical proximity, the risk may be contained in certain environments. However, organizations should remain vigilant and implement necessary security measures.

With the increasing reliance on wireless connectivity, securing BLE connections has become critical. Organizations should regularly review their security configurations and ensure that their devices are protected against unauthorized access.

Vulnerability Details

The vulnerability classified under CWE-277, indicates improper permissions regarding BLE connections. The official CVE description outlines that the vulnerability allows unauthorized access without authentication, impacting the availability of services for legitimate users.

The CVSS score of 6.5 highlights the potential for high impact on availability, with an attack vector classified as adjacent network, low attack complexity, and no privileges or user interaction required for exploitation.

The affected product is Agasta Easytouch+ with firmware version 9.3.97, with the vulnerability disclosed on October 2, 2025.

Technical Analysis

The root cause of the vulnerability lies in the lack of proper authentication mechanisms for BLE connections. This oversight allows unauthorized applications to connect and disrupt legitimate services.

The attack vector utilizes Bluetooth Low Energy, requiring an attacker to be within proximity. The attack complexity is low, as it does not require any special privileges or user interaction, making it easier for potential attackers to exploit.

The availability impact is classified as high, indicating that legitimate users may experience disruptions in service. This is particularly concerning for environments where BLE connections are critical for functionality.

Risk & Impact Analysis

Risk to organizations includes potential denial of service where legitimate applications cannot connect. Given the nature of BLE, this vulnerability could affect various applications relying on Bluetooth connectivity, leading to operational challenges.

Organizations should assess their risk profile, especially those utilizing BLE technology in critical applications. With the convenience of wireless technology comes the necessity for robust security measures to minimize the impact of such vulnerabilities.

Given the CVSS score, organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with unauthorized access and service disruption.

Exploitation Status

Affected Versions

The affected version is Agasta Easytouch+ firmware version 9.3.97. Organizations should ensure that they are using the latest firmware version to avoid the risks associated with this vulnerability.

Mitigation & Remediation

Organizations should prioritize patching immediately to address this vulnerability. Ensure that devices are updated to the latest firmware version provided by Agasta. If the patch is not yet available, consider implementing temporary workarounds such as disabling BLE functionality until the patch can be applied.

For enhanced security, organizations can also consider configuration hardening to limit BLE access only to authenticated applications, thereby reducing the potential attack surface.

Monitoring for unusual access patterns and enabling alerts for unauthorized BLE connections can provide additional layers of security.

Detection Guidance

Organizations should monitor logs for indicators of unauthorized BLE connection attempts. Behavioral anomalies in application access patterns can indicate potential exploitation of this vulnerability. Network signatures related to BLE traffic should also be analyzed for any unusual activity.

Furthermore, any unexpected changes in device configurations should be promptly investigated to ensure that unauthorized changes have not been made.

AppSecure Threat Intelligence Insight

The long-term significance of this vulnerability lies in the increasing reliance on wireless technologies and the necessity for robust security protocols around them. As organizations adopt more IoT devices, vulnerabilities like CVE-2025-56019 highlight the importance of securing BLE connections.

This vulnerability represents a trend where insufficient security measures in wireless communication protocols can lead to severe operational disruptions. Lessons learned should prompt security teams to reassess their wireless security policies.

Organizations should consider adopting comprehensive security frameworks that include regular assessments and updates to wireless protocols, alongside incident response strategies tailored for wireless vulnerabilities. For more insights on securing wireless communications, organizations can explore cloud penetration testing and penetration testing methodology as part of their security strategy.

In conclusion, the CVE-2025-56019 vulnerability serves as a crucial reminder of the need for vigilant security practices, especially as connectivity continues to expand in modern technology.
