CVE-2025-58682 is a vulnerability classified as CWE-79, which pertains to Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the Timur Kamaev Kama Click Counter product, versions up to and including 4.0.4. The flaw allows an attacker to inject malicious scripts that are stored persistently (Stored XSS) within the application. When a user accesses the affected web page, the malicious script executes in their browser context, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is necessary. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability to a limited extent. No known exploits have been reported in the wild, and no patches or fixes have been linked yet. The vulnerability arises from insufficient input sanitization or encoding during web page generation, allowing malicious payloads to be stored and later executed in users' browsers.

For European organizations using the Kama Click Counter, this vulnerability poses a risk of client-side attacks that can compromise user sessions, steal sensitive information, or manipulate user interactions. Since the vulnerability is a stored XSS, it can affect multiple users over time, increasing the attack surface. Organizations that rely on this tool for web analytics or user interaction tracking could see reputational damage if attackers exploit this flaw to deliver phishing payloads or malware. The medium severity suggests that while the impact is not catastrophic, it can lead to significant data leakage or unauthorized actions, especially if combined with other vulnerabilities or social engineering. The requirement for low privileges and user interaction means that internal users or authenticated users could be targeted to escalate the attack. In regulated European environments, such as those under GDPR, exploitation leading to data breaches could result in compliance violations and financial penalties.

Organizations should immediately review their use of the Kama Click Counter and monitor for updates or patches from the vendor. In the absence of an official patch, applying web application firewall (WAF) rules to detect and block suspicious input patterns related to XSS payloads can reduce risk. Input validation and output encoding should be enforced at the application level to sanitize user inputs before storage and rendering. Additionally, implementing Content Security Policy (CSP) headers can help mitigate the impact of XSS by restricting script execution sources. Regular security audits and penetration testing focusing on XSS vulnerabilities should be conducted. User awareness training to recognize suspicious links or behaviors can reduce the likelihood of successful exploitation. Finally, organizations should consider isolating or replacing the affected component if feasible until a secure version is available.
