CVE-2023-0676 Scanner

phpIPAM is an open-source IP address management system, commonly used in IT environments to centralize and automate tasks related to IP space management. Especially prevalent in medium to large enterprise networks, phpIPAM helps network administrators efficiently manage IP addresses and networks, ensuring proper tracking and reporting of IP allocation. It's equipped with various features including VLAN management, VRF support, and powerDNS integration. Network administrators and IT professionals frequently employ phpIPAM to aid in the reduction of IP conflicts and to streamline network management processes. Open-source and community-driven, it continuously evolves to address the requirements of modern network management.

Cross-Site Scripting (XSS) is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. It is a widespread problem that can lead to a variety of harmful consequences, including the theft of sensitive information such as cookies and session tokens. XSS vulnerabilities often exploit a web browser’s trust in the content delivered from a trusted site, allowing attackers to execute scripts in the context of the user's session. This poses a significant risk as it can lead to unauthorized actions or information disclosure. The vulnerability undermines an application’s security model and can harm the reputation and trustworthiness of affected applications.

The vulnerability in phpIPAM, identified as a Cross-Site Scripting (XSS) issue, is located within a specific functionality that accepts user input without sufficiently sanitizing or validating it before reflecting it back to the user. This lack of proper input handling allows an attacker to execute arbitrary scripts in the victim’s browser by injecting malicious code via input fields. The exploitation is achieved when the injected script is executed as part of the document object model processed by the victim's web browser. The vulnerable parameter is found in requests related to the bandwidth calculator tool in phpIPAM. The manipulation can be carried out with a crafted payload, often involving JavaScript fragments, submitted to the affected endpoint resulting in the unauthorized execution of scripts.

When the XSS vulnerability in phpIPAM is exploited, it could lead to unauthorized access and control over user sessions. Attackers may steal session identifiers or cookies, thereby gaining access to user accounts and sensitive information stored within phpIPAM, which can be exploited for further nefarious activities. Additionally, the execution of arbitrary scripts can result in the manipulation of content visible to users, redirecting them to malicious websites, or conducting phishing attacks to gather more information from unsuspecting individuals. The exploitation significantly compromises the integrity and confidentiality of the data managed by phpIPAM, risking network misconfiguration, reputation damage, and trust loss.
