CVE-2025-50574 identifies a cross-site scripting (XSS) vulnerability in the blog-details.php component of Hiruna Gallage's Glamour Salon Management System version 1. This vulnerability arises because the application fails to properly sanitize or encode user-supplied input in the blog comment section parameter, allowing remote attackers to inject arbitrary JavaScript or HTML code. When a victim user views the affected blog page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or defacement of the web interface. The vulnerability requires no authentication (AV:N) and has low attack complexity (AC:L), but it does require user interaction (UI:R) since the victim must visit the maliciously crafted page. The scope is changed (S:C) because the injected script can affect other users viewing the page. The impact affects confidentiality and integrity at a low level (C:L, I:L), with no impact on availability (A:N). Although no known exploits are currently reported in the wild, the vulnerability is classified as medium severity with a CVSS 3.1 base score of 6.1. The root cause is improper input validation and output encoding, a classic CWE-79 issue. The Glamour Salon Management System is typically used by small to medium-sized salon businesses for managing appointments, blogs, and customer interactions, making it a niche but potentially impactful target for attackers aiming to compromise customer trust or steal session information.

For European organizations using the Glamour Salon Management System, this XSS vulnerability could lead to unauthorized disclosure of user session tokens or credentials, enabling attackers to impersonate legitimate users. This can result in unauthorized access to customer data, manipulation of blog content, or phishing attacks targeting salon clients. While the system is unlikely to be critical infrastructure, the reputational damage and potential data privacy violations under GDPR could have legal and financial consequences. The vulnerability does not affect system availability but compromises data integrity and confidentiality. Small and medium enterprises in the beauty and wellness sector across Europe could be targeted, especially those with public-facing blogs or customer interaction portals. The lack of known exploits suggests limited current impact, but the ease of exploitation means attackers could weaponize this vulnerability quickly once discovered.

To mitigate CVE-2025-50574, organizations should implement strict input validation on the blog comment parameters, ensuring that all user-supplied data is sanitized to remove or encode HTML and script tags. Employing context-aware output encoding (e.g., HTML entity encoding) before rendering user input in the browser is critical. Web application firewalls (WAFs) can provide an additional layer of defense by detecting and blocking malicious payloads targeting the comment section. Disabling or restricting HTML content in user comments can reduce attack surface. Regularly updating the Glamour Salon Management System to incorporate vendor patches or security updates is essential once available. Additionally, educating users about the risks of clicking on suspicious links and monitoring web logs for unusual activity can help detect exploitation attempts. Implementing Content Security Policy (CSP) headers can further mitigate the impact of injected scripts by restricting script execution sources.
