CVE-2025-55372 is an arbitrary file upload vulnerability affecting the Beakon Application versions prior to 5.4.3. This vulnerability allows an attacker to upload a crafted file to the application, which can then be executed on the server, leading to arbitrary code execution. Arbitrary file upload vulnerabilities typically arise when an application fails to properly validate or sanitize files uploaded by users, allowing malicious files such as web shells or scripts to be stored and executed. Successful exploitation of this vulnerability would enable an attacker to gain control over the affected system, potentially leading to unauthorized access, data theft, or further network compromise. The lack of a CVSS score suggests that the vulnerability is newly disclosed and has not yet been fully assessed. There are no known exploits in the wild at the time of publication, and no official patches or mitigation links have been provided yet. The vulnerability was reserved on August 13, 2025, and published on September 2, 2025, indicating recent discovery. The absence of detailed affected versions and CWE identifiers limits the granularity of technical analysis, but the core risk remains high due to the nature of arbitrary file upload flaws.

For European organizations using the Beakon Application, this vulnerability poses a significant risk. If exploited, attackers could execute arbitrary code on critical systems, potentially leading to data breaches, service disruption, or lateral movement within corporate networks. This could affect confidentiality by exposing sensitive data, integrity by allowing unauthorized modifications, and availability by causing system outages or ransomware deployment. Given the arbitrary code execution capability, attackers could establish persistent backdoors or exfiltrate intellectual property. The impact is particularly severe for sectors with high regulatory requirements such as finance, healthcare, and government institutions in Europe, where data protection laws like GDPR impose strict obligations. Additionally, organizations relying on Beakon for operational technology or critical infrastructure monitoring could face operational disruptions with broader societal implications.

European organizations should immediately inventory their use of the Beakon Application and identify any instances running versions prior to 5.4.3. Until an official patch is released, organizations should implement strict file upload controls, including validating file types, restricting upload directories, and employing application-layer firewalls to detect and block suspicious payloads. Network segmentation should be enforced to limit the impact of a compromised system. Monitoring for unusual file uploads and execution attempts is critical, leveraging endpoint detection and response (EDR) tools and security information and event management (SIEM) systems. Organizations should also prepare incident response plans tailored to arbitrary code execution scenarios. Once a patch becomes available, rapid deployment is essential. Additionally, applying the principle of least privilege to application and server accounts can reduce exploitation impact. Regular security assessments and penetration testing focused on file upload mechanisms are recommended to proactively identify similar weaknesses.
