CVE-2025-10632 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the itsourcecode Online Petshop Management System, specifically within the Admin Dashboard component's availableframe.php file. The vulnerability arises from improper sanitization or validation of user-supplied input in the 'name/address' argument, allowing an attacker to inject malicious scripts. Since the attack vector is remote and does not require prior authentication, an attacker can exploit this flaw by crafting a specially crafted URL or input that, when processed by the vulnerable function, executes arbitrary JavaScript code in the context of the victim's browser session. The CVSS 4.0 score of 5.1 (medium severity) reflects that the attack requires no privileges and no user interaction but has limited impact on confidentiality and integrity, with no impact on availability. The vulnerability could lead to session hijacking, defacement, or redirection to malicious sites, potentially compromising administrative accounts or user data within the petshop management system. Although no public exploit is currently known to be actively used in the wild, the existence of a public exploit increases the risk of exploitation. The lack of available patches or mitigations from the vendor further elevates the urgency for affected organizations to implement defensive measures.

For European organizations utilizing the itsourcecode Online Petshop Management System 1.0, this vulnerability poses a risk primarily to the confidentiality and integrity of administrative sessions and data. Successful exploitation could allow attackers to hijack admin sessions, manipulate petshop management data, or conduct phishing attacks targeting internal users. Given that the system is used for managing petshop operations, the direct impact on critical infrastructure is limited; however, compromised credentials or session data could be leveraged for broader network access or lateral movement within an organization. Additionally, exploitation could damage the organization's reputation and customer trust, especially if customer data is exposed or manipulated. The medium severity indicates a moderate risk, but the ease of remote exploitation without authentication means organizations should not underestimate the threat. European organizations with online petshop management operations or those using this specific software version are at risk, particularly if the system is accessible from the internet or internal networks without adequate protections.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Applying strict input validation and output encoding on all user-supplied data, especially the 'name/address' fields in the Admin Dashboard, to neutralize malicious scripts. 2) Restricting access to the Admin Dashboard via network segmentation, VPNs, or IP whitelisting to limit exposure to trusted users only. 3) Employing web application firewalls (WAFs) with custom rules to detect and block typical XSS attack patterns targeting the vulnerable parameter. 4) Enforcing multi-factor authentication (MFA) for administrative accounts to reduce the impact of session hijacking. 5) Monitoring logs for suspicious activity related to the availableframe.php endpoint and anomalous input patterns. 6) Educating administrators and users about phishing risks and signs of XSS exploitation. 7) Planning for an upgrade or migration to a patched or alternative system version once available. These targeted measures go beyond generic advice by focusing on the specific vulnerable component and attack vectors.
