CVE-2025-49067: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in NasaTheme Nasa Core
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in NasaTheme Nasa Core allows Stored XSS.This issue affects Nasa Core: from n/a before 6.4.1.
AI Analysis
Technical Summary
CVE-2025-49067 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the NasaTheme Nasa Core product prior to version 6.4.1. This vulnerability arises due to improper neutralization of input during web page generation, allowing malicious actors to inject and persist executable scripts within the application. When a victim user accesses the compromised page, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability requires low privileges (PR:L) and user interaction (UI:R) to exploit, but it can impact confidentiality, integrity, and availability due to the scope (S:C) of the vulnerability, meaning it can affect resources beyond the vulnerable component. The CVSS score of 6.5 (medium severity) reflects these factors, indicating a significant but not critical risk. No known exploits are currently reported in the wild, and no official patches have been linked yet. Stored XSS vulnerabilities are particularly dangerous because the malicious payload is saved on the server and served to multiple users, increasing the potential impact. NasaTheme Nasa Core is a web theme product, likely used in content management systems or websites, where user-generated content or input fields are present and insufficiently sanitized or encoded before rendering.
Potential Impact
For European organizations using NasaTheme Nasa Core, this vulnerability poses a risk of client-side attacks that can compromise user accounts, steal sensitive data, or manipulate web sessions. Organizations in sectors such as government, education, or public services that rely on NasaTheme for their web presence may face reputational damage and regulatory scrutiny under GDPR if personal data is exposed or misused. The stored nature of the XSS means multiple users can be affected once the malicious payload is injected, amplifying the potential damage. Additionally, attackers could leverage this vulnerability as a foothold for further attacks, including phishing or spreading malware. The medium severity suggests that while the vulnerability is serious, exploitation requires some user interaction and privileges, which may limit immediate widespread impact but still demands prompt attention.
Mitigation Recommendations
European organizations should prioritize upgrading NasaTheme Nasa Core to version 6.4.1 or later once available, as this version addresses the vulnerability. Until patches are released, organizations should implement strict input validation and output encoding on all user inputs, especially those rendered on web pages. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Conduct thorough code reviews and penetration testing focused on XSS vectors within the application. Additionally, monitor web application logs for suspicious input patterns or repeated injection attempts. Educate users about the risks of interacting with untrusted content and consider implementing web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting NasaTheme. Finally, ensure incident response plans include procedures for handling XSS incidents to minimize damage and recovery time.
