CVE-2025-10913 is a Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the TemizlikYolda product developed by Saastech Cleaning and Internet Services Inc. The vulnerability stems from improper neutralization of user input during the generation of web pages, which allows attackers to inject and execute arbitrary scripts in the context of the victim's browser. This can lead to theft of session tokens, redirection to malicious sites, or execution of unauthorized actions on behalf of the user. The vulnerability affects all versions up to 11022026, with no patches currently available and no response from the vendor despite early disclosure. The CVSS v3.1 score is 8.3, indicating high severity, with an attack vector of network (remote exploitation), low attack complexity, requiring low privileges but no user interaction. The impact includes partial confidentiality loss, high integrity compromise, and high availability disruption. Although no known exploits are currently in the wild, the lack of vendor response and absence of patches increase the risk of future exploitation. The vulnerability is particularly critical for web-facing components of TemizlikYolda, which is used in cleaning and internet services management, potentially exposing sensitive customer and operational data.

For European organizations using TemizlikYolda, this vulnerability poses a significant risk of data theft, unauthorized actions, and service disruption. Attackers exploiting this XSS flaw can hijack user sessions, manipulate web content, or perform actions with the privileges of legitimate users, potentially leading to data breaches or operational interruptions. The impact is heightened in sectors relying on TemizlikYolda for managing cleaning services, where customer privacy and service availability are critical. Additionally, the absence of vendor patches and the vendor's non-responsiveness increase the window of exposure. This could lead to reputational damage, regulatory penalties under GDPR for data breaches, and financial losses. The vulnerability's network accessibility and low complexity make it a feasible target for attackers, increasing the urgency for mitigation in European environments.

1. Implement strict input validation and output encoding on all user-supplied data within TemizlikYolda to prevent script injection. 2. Deploy a Web Application Firewall (WAF) with rules tailored to detect and block XSS attack patterns targeting TemizlikYolda endpoints. 3. Conduct thorough code reviews and security testing focusing on input handling and output rendering in the application. 4. Isolate TemizlikYolda instances within segmented network zones to limit lateral movement in case of compromise. 5. Monitor web server logs and application behavior for unusual requests or anomalies indicative of exploitation attempts. 6. Educate users and administrators about the risks of XSS and encourage vigilance for suspicious activity. 7. Engage with Saastech Cleaning and Internet Services Inc. for updates or patches, and consider alternative solutions if remediation is delayed. 8. Apply Content Security Policy (CSP) headers to restrict script execution sources and reduce XSS impact. 9. Regularly update underlying web server and platform components to minimize other attack vectors.
