CVE-2025-46474 is a high-severity vulnerability classified under CWE-98, which involves improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the SEUR Oficial software, a product used by the SEUR logistics and parcel delivery company. The flaw allows an attacker to perform a PHP Local File Inclusion (LFI) attack by manipulating the filename parameter that is included or required by the PHP application. This can lead to arbitrary code execution, disclosure of sensitive files, and potentially full system compromise. The vulnerability is exploitable remotely over the network without requiring authentication or user interaction, although it has a high attack complexity, meaning some conditions must be met for successful exploitation. The CVSS v3.1 score is 8.1, indicating a high impact on confidentiality, integrity, and availability. The vulnerability affects versions of SEUR Oficial up to 2.2.23, with no patch currently available. While no known exploits are reported in the wild yet, the nature of LFI vulnerabilities makes them attractive targets for attackers aiming to escalate privileges or pivot within compromised environments. The vulnerability arises from insufficient validation or sanitization of user-supplied input used in file inclusion functions, allowing attackers to specify arbitrary files on the server to be included and executed by the PHP interpreter.

For European organizations, especially those relying on SEUR Oficial for logistics and parcel management, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive business data, including shipment details, customer information, and internal operational files. Attackers could execute arbitrary code on affected servers, potentially disrupting logistics operations, causing denial of service, or using compromised systems as footholds for further network intrusion. Given SEUR's prominence in Spain and other European countries, organizations using this software could face operational downtime and reputational damage. Furthermore, the breach of customer data could lead to regulatory penalties under GDPR, as personal data confidentiality and integrity are at risk. The lack of a patch increases exposure time, and the remote exploitability without authentication heightens the threat level. Organizations integrating SEUR Oficial into their IT infrastructure must consider the potential cascading effects on supply chain security and customer trust.

Immediate mitigation steps include implementing strict input validation and sanitization on all parameters used in include or require statements within the PHP application. Organizations should conduct code reviews to identify and remediate unsafe file inclusion patterns. Employing web application firewalls (WAFs) with rules to detect and block LFI attack patterns can provide temporary protection. Restricting PHP's file inclusion functions via configuration settings such as disabling allow_url_include and setting open_basedir restrictions can limit the attack surface. Monitoring logs for suspicious file inclusion attempts and anomalous PHP errors is critical for early detection. Since no official patch is available, organizations should coordinate with SEUR Oficial vendors for updates or consider isolating affected systems within segmented network zones to reduce impact. Additionally, applying the principle of least privilege to the web server and PHP process can minimize damage if exploitation occurs. Backup and incident response plans should be reviewed and tested to ensure rapid recovery.
