CVE-2025-0471 is a critical vulnerability affecting the PMB platform from SIGB, specifically versions 4.0.10 and above. This vulnerability allows for unrestricted file uploads, enabling attackers to upload malicious files that could lead to remote access of the machine. The ability to access, modify, and execute commands freely poses significant risks to organizations using this platform.
The CVSS score assigned to this vulnerability is 9.9, indicating its critical nature. The high severity arises from its potential impact on confidentiality, integrity, and availability, all rated as high. Organizations using the PMB platform should recognize the urgency of addressing this vulnerability, as it could lead to severe consequences if exploited.
Currently, there are no known exploits in the wild for this vulnerability, but the nature of unrestricted file uploads makes it a prime target for attackers. Organizations are urged to prioritize patching to mitigate this risk.
Organizations should prioritize patching immediately to safeguard their systems against this vulnerability.
Vulnerability Details
The PMB platform has a critical unrestricted file upload vulnerability, which allows attackers to upload files that can lead to full remote access. The official description states: 'This vulnerability could allow an attacker to upload a file to gain remote access to the machine, being able to access, modify and execute commands freely.' The CVSS score of 9.9 indicates a critical severity level, making this a priority for remediation.
The vulnerability is classified under CWE-434, indicating an issue with unrestricted file uploads. The attack vector is network-based, and the complexity is low, requiring only low privileges. User interaction is not necessary, making it even more dangerous.
Technical Analysis
The root cause of this vulnerability lies in inadequate validation of uploaded files, allowing malicious files to be accepted by the system. Attackers can exploit this by uploading scripts or executables that can be executed on the server, leading to unauthorized access.
The attack vector is network-based, and the complexity is low, meaning that even attackers with limited skills can exploit this vulnerability. The required privileges are low, and no user interaction is necessary, increasing the risk of exploitation.
The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability. Successful exploitation could lead to not only loss of data but also disruption of services.
Risk & Impact Analysis
Organizations utilizing the PMB platform should be acutely aware of the potential risks posed by this vulnerability. Given its high CVSS score of 9.9, the vulnerability is a significant threat that could be exploited to conduct a wide range of malicious activities.
The blast radius of this vulnerability is considerable, affecting all instances of PMB versions 4.0.10 and above. Attackers could leverage this vulnerability to gain full control over compromised systems, leading to data breaches or system downtime.
The urgency for remediation is critical. Organizations should prioritize patching this vulnerability to prevent potential exploitation. The lack of known exploits does not diminish the risk, as unrestricted file uploads are a well-known attack vector.
