Vulnerability Details
In Cleo Harmony before 5.8.0.21, VLTrader before 5.8.0.21, and LexiCom before 5.8.0.21, there is an unrestricted file upload and download that could lead to remote code execution. The vulnerability falls under the CWE classification of CWE-434, which signifies issues related to improper restriction of file type.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a network attack vector, low attack complexity, and no privileges or user interaction required. This presents a high confidentiality, integrity, and availability impact.
Technical Analysis
The root cause of CVE-2024-50623 stems from inadequate validation of file uploads, allowing attackers to upload malicious files that can be executed on the server. The attack vector is primarily network-based, with low complexity in executing the attack. No privileges are required, and user interaction is not necessary to exploit this vulnerability.
The confidentiality, integrity, and availability impacts are all rated high, indicating that successful exploitation could lead to unauthorized access to sensitive information, alteration of data, and disruption of services.
Risk & Impact Analysis
The real-world risk of this vulnerability is substantial. Organizations using Cleo products must assess the potential blast radius, considering the possibility of remote code execution. If exploited, attackers could gain full control over affected systems, leading to data exfiltration or further network compromise.
Given the CVSS score and the confirmation of known exploits, organizations should address this vulnerability in their priority patch cycle. The urgency is critical, and failure to act could result in severe consequences.
