CVE-2025-5797 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the code-projects Laundry System, specifically affecting the /data/insert_type.php endpoint. The vulnerability arises from improper handling and sanitization of the 'Type' parameter, which allows an attacker to inject malicious scripts that execute in the context of the victim's browser. This vulnerability is remotely exploitable without requiring authentication, although it requires some user interaction (such as a victim clicking a crafted link or visiting a malicious page). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The vector string (AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P) shows that the attack is network-based, requires low attack complexity, no privileges, but some user interaction, and results in limited integrity impact with no confidentiality or availability impact. The vulnerability has been publicly disclosed but there are no known exploits in the wild at this time. The lack of a patch link suggests that a fix may not yet be available, increasing the urgency for mitigation. XSS vulnerabilities like this can be leveraged for session hijacking, defacement, phishing, or delivering malicious payloads, potentially compromising user trust and data integrity within the Laundry System application environment.

For European organizations using the code-projects Laundry System 1.0, this vulnerability could lead to unauthorized script execution in users' browsers, potentially enabling attackers to steal session cookies, impersonate users, or conduct phishing attacks. While the direct impact on confidentiality and availability is limited, the integrity of user interactions and data could be compromised. This is particularly concerning for organizations handling sensitive customer information or payment data through the Laundry System. Additionally, exploitation could damage the organization's reputation and customer trust. Since the vulnerability requires user interaction, social engineering tactics could be employed to increase success rates. The medium severity rating indicates a moderate risk, but the absence of a patch and public disclosure raises the urgency for European entities to assess exposure and implement mitigations promptly.

European organizations should immediately audit their deployments of code-projects Laundry System to identify any instances of version 1.0. Until a vendor patch is available, implement the following mitigations: 1) Employ web application firewalls (WAFs) with rules to detect and block malicious input patterns targeting the 'Type' parameter in /data/insert_type.php. 2) Sanitize and validate all user inputs on the server side, especially the 'Type' parameter, to neutralize script tags or suspicious characters. 3) Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Educate users and staff about phishing and social engineering risks related to XSS attacks. 5) Monitor logs for unusual requests or error messages related to the vulnerable endpoint. 6) If feasible, isolate or restrict access to the Laundry System application to trusted networks or VPNs to reduce exposure. 7) Plan and prioritize upgrading to a patched or newer version once available. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable parameter and endpoint, combined with network-level protections and user awareness.
