CVE-2025-45786 identifies a Cross Site Scripting (XSS) vulnerability in Real Estate Management version 1.0, specifically within the /store/index.php endpoint. XSS vulnerabilities occur when an application does not properly sanitize user-supplied input, allowing attackers to inject malicious scripts that execute in the context of other users' browsers. In this case, the vulnerability resides in a web-based real estate management system, which likely handles sensitive client and property data. The lack of input validation or output encoding in the affected endpoint enables attackers to craft malicious URLs or form inputs that, when accessed by legitimate users, execute arbitrary JavaScript code. This can lead to session hijacking, credential theft, defacement, or redirection to malicious sites. Although no specific affected versions beyond 1.0 are listed and no patches are currently available, the vulnerability is publicly disclosed as of June 18, 2025, and no known exploits in the wild have been reported yet. The absence of a CVSS score suggests the vulnerability is newly published and not yet fully assessed. However, the technical nature of XSS and its common exploitation vectors are well understood in cybersecurity communities.

For European organizations using Real Estate Management 1.0, this XSS vulnerability poses a significant risk to confidentiality and integrity of user sessions and data. Real estate platforms often manage personally identifiable information (PII), financial details, and contractual documents, making them attractive targets for attackers seeking to steal sensitive data or conduct fraud. Successful exploitation could allow attackers to impersonate legitimate users, manipulate displayed content, or inject phishing payloads, potentially damaging organizational reputation and client trust. The impact is heightened in Europe due to stringent data protection regulations such as GDPR, where data breaches can result in substantial fines and legal consequences. Additionally, availability impact is generally low for XSS, but indirect effects such as user lockout or service disruption through malicious script execution cannot be fully excluded. Since no authentication requirement or user interaction specifics are provided, it is prudent to assume that exploitation may require victim interaction (e.g., clicking a crafted link), which could limit automated mass exploitation but still poses a serious threat in targeted attacks.

Given the lack of official patches, European organizations should implement immediate compensating controls. First, apply rigorous input validation and output encoding on all user-supplied data within /store/index.php to neutralize script injection vectors. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. Conduct thorough code reviews and penetration testing focused on XSS vectors in the affected application module. If possible, isolate the vulnerable application behind web application firewalls (WAFs) configured to detect and block XSS payloads. Educate users and administrators about the risks of clicking untrusted links and encourage the use of updated browsers with built-in XSS protections. Monitor web logs for suspicious requests targeting the vulnerable endpoint. Finally, engage with the vendor or development team to prioritize the release of an official patch or updated version addressing this vulnerability.
