CVE-2024-48534 is a reflected cross-site scripting (XSS) vulnerability identified in the Camp Details module of eSoft Planner version 3.24.08271-USA. Reflected XSS occurs when an application includes untrusted user input in a web page without proper validation or encoding, allowing attackers to inject malicious JavaScript code. In this case, the vulnerability enables attackers to craft a URL or input payload that, when visited or submitted by an authenticated user, executes arbitrary scripts within the victim's browser context. This can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, requiring privileges and user interaction, with impacts on confidentiality and integrity but not availability. The vulnerability is categorized under CWE-79 (Improper Neutralization of Input During Web Page Generation). No patches or known exploits are currently available, indicating that organizations must rely on interim mitigations until an official fix is released. The vulnerability's scope is limited to users who access the vulnerable module and interact with maliciously crafted inputs, emphasizing the importance of user awareness and input sanitization.

The primary impact of CVE-2024-48534 is on the confidentiality and integrity of user sessions within eSoft Planner. Attackers can steal session cookies, impersonate users, or manipulate displayed content, potentially leading to unauthorized access or data leakage. While availability is not directly affected, the exploitation could facilitate further attacks such as privilege escalation or lateral movement within an organization. Organizations relying on eSoft Planner for camp management or scheduling may face risks of compromised user accounts and data integrity issues. The requirement for user interaction and low privileges reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, especially in environments with high-value data or users with elevated privileges. The absence of known exploits in the wild currently limits immediate risk but also suggests the need for proactive defense measures.

1. Implement strict input validation and output encoding on the Camp Details module to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Educate users to avoid clicking on suspicious or unsolicited links, especially those targeting the eSoft Planner interface. 4. Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 5. Use web application firewalls (WAFs) configured to detect and block reflected XSS payloads targeting known vulnerable endpoints. 6. Segregate user roles and minimize privileges to reduce the impact of compromised accounts. 7. Regularly check for and apply vendor patches or updates once available. 8. Consider implementing multi-factor authentication (MFA) to mitigate session hijacking risks. 9. Conduct security assessments and penetration testing focused on XSS vulnerabilities in the affected module.
