CVE-2024-55514 is a vulnerability identified in several Raisecom network devices, specifically the MSG1200, MSG2100E, MSG2200, and MSG2300 models running firmware version 3.90. The vulnerability resides in the web interface component /upload_sfmig.php, which improperly validates the form name parameter during file upload operations. By crafting a malicious form name, an attacker can upload arbitrary files to the server. This capability can lead to unauthorized access to server permissions, potentially allowing attackers to execute arbitrary code, modify system files, or disrupt device operations. The vulnerability is classified under CWE-434 (Unrestricted Upload of File with Dangerous Type). The CVSS v3.1 base score is 6.3, indicating a medium severity with network attack vector, low attack complexity, no privileges required, but requiring user interaction. The scope is unchanged, and the impact affects confidentiality, integrity, and availability at a low level. No patches or official mitigations have been released at the time of publication, and there are no known exploits in the wild. This vulnerability poses a risk primarily to organizations relying on these Raisecom devices for network infrastructure, especially in telecommunications and enterprise environments.

The vulnerability allows attackers to upload arbitrary files without authentication, which can lead to unauthorized access to server permissions. This can compromise the confidentiality of sensitive data stored or processed by the device, integrity of system files and configurations, and availability of network services if the device is manipulated or disrupted. Exploitation could enable attackers to execute malicious code, establish persistent access, or cause denial of service. Given the affected devices are network infrastructure components, successful exploitation could impact large segments of an organization's network, potentially disrupting critical communications or services. The lack of authentication requirement increases the risk, although user interaction is necessary, which may limit automated exploitation. Organizations worldwide using these Raisecom devices in their network infrastructure face potential operational and security risks if this vulnerability is exploited.

Organizations should immediately review and restrict access to the web interface of affected Raisecom devices, ideally limiting it to trusted management networks and IP addresses. Implement network segmentation and firewall rules to prevent unauthorized external access to device management interfaces. Monitor device logs for unusual file upload attempts or suspicious activity related to /upload_sfmig.php. Until an official patch is released, consider disabling or restricting the vulnerable upload functionality if possible through device configuration. Employ web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block malicious file upload attempts targeting this endpoint. Regularly update device firmware and subscribe to vendor advisories for timely patch deployment once available. Conduct internal security assessments and penetration tests focusing on device management interfaces to identify and remediate similar weaknesses. Educate administrators about the risks of interacting with suspicious links or forms that could trigger the vulnerability.
