CVE-2025-0473 is a medium-severity vulnerability identified in the PMB platform, which affects versions 4.0.10 and above. This vulnerability allows attackers to persist temporary files on the server by exploiting the file upload functionality at the '/pmb/authorities/import/iimport_authorities' endpoint. The inherent workflow of this endpoint creates a temporary file that should be deleted after a POST request is sent to the same endpoint. However, attackers can manipulate this process to prevent the deletion of the temporary file.
The vulnerability has a CVSS score of 6.5, indicating a medium severity level. This score reflects a potential risk to organizations, as it allows for unauthorized access to sensitive data due to the high confidentiality impact. As the vulnerability has been analyzed, organizations need to understand its implications and take appropriate measures to mitigate risks.
Currently, there are no public exploits or proof-of-concept code available for this vulnerability. However, it is important for organizations to prioritize patching affected versions to prevent any potential exploitation. The vulnerability was disclosed on January 16, 2025, and organizations should assess their systems promptly to ensure they are not vulnerable.
Organizations should prioritize remediation based on their risk assessment and vulnerability management program. Immediate action is recommended to patch the affected versions and secure the PMB platform against potential attacks.
Vulnerability Details
The vulnerability in question allows attackers to persist temporary files on the server. The affected versions include PMB 4.0.10 and above. It is classified under CWE-459, which refers to 'Incomplete Cleanup of Temporary Files.' The vulnerability was officially published on January 16, 2025, and has been analyzed as part of the ongoing security assessments.
Technical Analysis
The root cause of this vulnerability is related to the file upload process within the PMB platform. When a user uploads a file, a temporary file is created by the server. This file is intended to be deleted after the client sends a POST request; however, attackers can manipulate the request flow to prevent this deletion, thereby leaving the temporary file on the server.
The attack vector is network-based, with low complexity involved. Attackers require low privileges to exploit this vulnerability, and no user interaction is necessary. The attack's success could lead to high confidentiality impacts, as sensitive data may be exposed through the persistent files.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data due to the temporary files being left on the server. The potential blast radius is significant, as this vulnerability affects all instances of the PMB platform from version 4.0.10 and above. Given the medium CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle.
Organizations should be proactive in their approach to vulnerability management, ensuring that they implement effective remediation strategies. The urgency of patching is moderate, and organizations may schedule this remediation based on their operational capacity.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of the PMB platform starting from version 4.0.10. Organizations should ensure that they apply the necessary patches to secure their systems.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply patches or updates provided by the vendor SIGB. If a patch is not available, organizations should consider implementing workarounds such as disabling the file upload functionality until a secure version is deployed. Additionally, configuration hardening and network controls should be reviewed to limit exposure.
Organizations should validate remediation through penetration testing to identify similar weaknesses.
Detection Guidance
Organizations should monitor logs for unusual file creation events, especially in the context of the file upload functionality. Behavioral anomalies such as repeated file uploads or failures in file deletion should also be flagged for investigation.
