CVE-2024-41355 identifies a Cross Site Scripting (XSS) vulnerability in phpipam version 1.6, a popular open-source IP address management (IPAM) tool. The vulnerability exists in the /app/tools/request-ip/index.php script, where insufficient sanitization of user-supplied input allows injection of malicious scripts. This reflected XSS flaw can be triggered by an authenticated user with low privileges (PR:L) who interacts with the vulnerable endpoint (UI:R). The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity, with an attack vector over the network (AV:N), low attack complexity (AC:L), and a scope change (S:C) that affects resources beyond the vulnerable component. Successful exploitation can lead to partial compromise of confidentiality, integrity, and availability, such as session hijacking, unauthorized actions, or denial of service. Although no public exploits are known, the vulnerability poses a risk in environments where phpipam is deployed, especially in enterprise or critical infrastructure contexts. The CWE-79 classification confirms the nature of the vulnerability as improper neutralization of input leading to XSS. The lack of available patches at the time of publication necessitates immediate mitigation efforts by administrators.

For European organizations, the impact of CVE-2024-41355 can be significant, particularly for those relying on phpipam 1.6 for managing IP address allocations in enterprise networks, data centers, or critical infrastructure. Exploitation could allow attackers to execute malicious scripts in the context of legitimate users, potentially leading to session hijacking, theft of sensitive information, or unauthorized configuration changes. This could disrupt network management operations and compromise network security. Given the medium severity and requirement for authentication, the threat is more relevant in insider threat scenarios or where user credentials are compromised. The reflected XSS could also be leveraged as a stepping stone for more advanced attacks targeting network infrastructure. Organizations in sectors such as telecommunications, finance, government, and energy, which often use IPAM tools extensively, may face operational risks and regulatory compliance challenges if exploited.

To mitigate CVE-2024-41355, organizations should implement the following specific measures: 1) Apply input validation and output encoding on all user-supplied data in the /app/tools/request-ip/index.php endpoint to neutralize malicious scripts. 2) Restrict access to the vulnerable endpoint to trusted users only, using network segmentation or access control lists. 3) Enforce strong authentication and monitor for unusual user activity that could indicate exploitation attempts. 4) If patches become available, prioritize timely updates of phpipam to the fixed version. 5) Employ Content Security Policy (CSP) headers to limit the impact of potential XSS payloads. 6) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities. 7) Educate users about the risks of interacting with suspicious links or inputs within the IPAM interface. These measures go beyond generic advice by focusing on the specific vulnerable component and operational context.
