CVE-2025-15174 is a cross-site scripting (XSS) vulnerability identified in the SohuTV CacheCloud product, affecting versions 3.0 through 3.2.0. The flaw exists in the doAppAuditList function within the AppManageController.java source file, where insufficient input sanitization allows attackers to inject malicious scripts into web responses. This vulnerability can be exploited remotely without authentication, but requires user interaction to trigger the malicious payload, such as an authenticated user visiting a crafted URL or interface page. The vulnerability was responsibly disclosed early to the vendor, but no patch or official response has been provided as of the publication date. The CVSS 4.0 base score is 5.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but user interaction needed, and limited impact on confidentiality and integrity. Successful exploitation could allow attackers to execute arbitrary JavaScript in the context of the victim’s browser, potentially leading to session hijacking, information disclosure, or manipulation of the web interface. While no known exploits are currently observed in the wild, the public disclosure increases the risk of exploitation. CacheCloud is a cache management platform used to optimize distributed caching services, often deployed in enterprise environments to improve application performance. The vulnerability primarily threatens the web management interface, which is typically accessible to administrators or internal users, but may be exposed externally in some deployments.

For European organizations, the impact of CVE-2025-15174 depends on the extent of CacheCloud deployment and exposure of its management interfaces. Exploitation could lead to unauthorized script execution within the context of authenticated users, potentially compromising session tokens or enabling phishing attacks targeting administrators. This may result in limited confidentiality breaches or integrity violations of cache management operations. While the vulnerability does not directly affect availability, successful exploitation could facilitate further attacks or unauthorized changes to cache configurations, indirectly impacting service reliability. Organizations relying on CacheCloud for critical caching infrastructure may face operational disruptions if attackers leverage this vulnerability to manipulate cache data or configurations. The lack of an official patch increases the risk window, especially for organizations with externally accessible management consoles. European entities in sectors such as finance, telecommunications, and e-commerce, which often use caching solutions to optimize performance, could be particularly affected if CacheCloud is part of their infrastructure. Additionally, regulatory requirements like GDPR emphasize protecting user data, and XSS vulnerabilities could lead to data exposure incidents subject to compliance penalties.

Given the absence of an official patch, European organizations should implement immediate compensating controls. First, restrict access to the CacheCloud management interface by enforcing network-level controls such as VPNs, IP whitelisting, or segmentation to limit exposure to trusted users only. Second, deploy web application firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting the vulnerable endpoint, especially the doAppAuditList function. Third, implement strict input validation and output encoding on the affected parameters if source code modification is feasible, sanitizing user inputs to neutralize malicious scripts. Fourth, educate administrators and users about the risk of clicking untrusted links or interacting with suspicious content related to CacheCloud interfaces. Fifth, monitor logs and network traffic for unusual activities or attempted exploitation patterns. Finally, maintain close communication with the vendor for updates and apply official patches promptly once available. Organizations should also consider alternative cache management solutions if the risk cannot be sufficiently mitigated in the short term.
