phpIPAM 1.5.1, an open-source IP address management application written in PHP, is affected by an SQL Injection vulnerability. This vulnerability arises from improper sanitization of user-supplied input in SQL queries, allowing attackers to inject malicious SQL code. Successful exploitation can lead to unauthorized retrieval, modification, or deletion of data stored in the backend database, which typically contains critical network information such as IP addresses, subnets, and device details. The exploit code has been published on Exploit-DB (ID 52444), indicating that the vulnerability is known and potentially exploitable in the wild, although no confirmed active exploitation has been reported yet. The lack of authentication or user interaction requirements in the provided information suggests that the attack surface may be broad, especially if the phpIPAM instance is exposed to untrusted networks. The absence of official patches or CVSS scoring complicates risk assessment but underscores the urgency for organizations to audit their phpIPAM installations. Given phpIPAM's role in network management, exploitation could disrupt network operations and compromise sensitive infrastructure data.

For European organizations, exploitation of this SQL Injection vulnerability in phpIPAM 1.5.1 could result in significant confidentiality breaches, exposing sensitive network topology and IP allocation data. Integrity of network management data could be compromised, leading to incorrect IP assignments or network misconfigurations, potentially causing service disruptions. Availability might also be affected if attackers manipulate or delete critical database records. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, face increased regulatory and operational risks. The presence of publicly available exploit code raises the likelihood of attacks, especially against externally accessible phpIPAM instances. The medium severity rating reflects a balance between the potential impact and the current lack of evidence for widespread exploitation.

European organizations should immediately inventory all phpIPAM 1.5.1 deployments and restrict access to trusted internal networks only, employing network segmentation and firewall rules to limit exposure. Since no official patch is currently available, consider upgrading to a later, patched version of phpIPAM if available, or apply community-recommended workarounds such as input validation and prepared statements to mitigate SQL Injection risks. Conduct thorough code reviews and penetration testing focused on SQL Injection vectors within phpIPAM. Implement web application firewalls (WAFs) with SQL Injection detection and prevention capabilities to block malicious requests. Regularly monitor logs for suspicious database query patterns and unauthorized access attempts. Educate IT staff on the risks and signs of SQL Injection exploitation. Finally, maintain regular backups of phpIPAM databases to enable recovery in case of data tampering or loss.
