CVE-2025-7063 in PAD CMS
Summary
by MITRE • 09/30/2025
Due to client-controlled permission check parameter, PAD CMS's file upload functionality allows an unauthenticated remote attacker to upload files of any type and extension without restriction, which can then be executed leading to Remote Code Execution. This issue affects all 3 templates: www, bip and ww+bip.
This product is End-Of-Life and producent will not publish patches for this vulnerability.

The vulnerability described in CVE-2025-7063 represents a critical security flaw in PAD CMS that stems from improper permission validation within its file upload mechanism. This weakness allows unauthenticated remote attackers to bypass access controls and upload arbitrary file types without any restrictions on content or extension. The vulnerability specifically impacts three distinct templates within the CMS: www, bip, and ww+bip, indicating a widespread issue across the product's deployment variants. The root cause lies in the client-controlled permission check parameter that should have validated user authentication and authorization before permitting file uploads, but instead accepted any input from remote clients without proper verification.
The technical implications of this vulnerability are severe and align with CWE-20, which describes improper input validation, and CWE-434, which covers unrestricted file upload. Attackers can exploit this flaw to upload malicious files such as web shells, scripts, or executables that can be executed on the target server. The lack of file type validation and extension filtering creates an environment where attackers can bypass security controls and potentially gain full control over the affected system. The vulnerability's impact extends beyond simple file uploads since the uploaded files can be executed directly, providing attackers with a direct path to remote code execution capabilities.
The operational impact of CVE-2025-7063 is particularly concerning given that PAD CMS is end-of-life and no patches or updates will be provided by the vendor. This means organizations using this CMS are left without official remediation options, creating a persistent security risk that cannot be addressed through standard patch management procedures. The vulnerability's exploitation does not require authentication, making it particularly dangerous as it can be leveraged by any remote attacker without prior access credentials. This characteristic aligns with ATT&CK technique T1190, which describes exploiting vulnerabilities in remote services, and T1059, which covers execution through command and scripting interpreters. The three affected templates suggest that the vulnerability exists at a core level rather than being isolated to specific implementations, making the risk assessment more comprehensive across all deployments.
Organizations currently utilizing PAD CMS should immediately implement network-level mitigations including firewall rules that restrict access to upload functionality, network segmentation to isolate affected systems, and monitoring for suspicious file upload activities. The absence of vendor patches necessitates the implementation of alternative security controls such as web application firewalls that can detect and block malicious file upload attempts. Additionally, administrators should conduct thorough audits of existing files on affected systems to identify any previously uploaded malicious content and consider decommissioning the affected CMS instances as a long-term solution. The vulnerability's nature as a privilege escalation issue through file upload operations also requires careful consideration of the principle of least privilege and regular security assessments to prevent unauthorized access to sensitive system resources.
