CVE-2025-15175 is a cross-site scripting vulnerability identified in SohuTV CacheCloud, a cloud caching management platform, affecting versions 3.0 through 3.2.0. The vulnerability resides in the doAppList/appCommandAnalysis function of the AppController.java source file, where insufficient input sanitization allows attackers to inject malicious JavaScript code. This flaw can be exploited remotely without authentication but requires user interaction, such as a victim clicking a crafted link or visiting a malicious page that triggers the payload. The vulnerability is classified as medium severity with a CVSS 4.0 score of 5.1, reflecting its moderate impact on confidentiality and integrity, limited availability impact, and ease of exploitation due to low attack complexity and no privileges required. The vendor was notified early but has not released a patch, and a public exploit is available, increasing the risk of exploitation. Successful exploitation can lead to session hijacking, theft of sensitive information, or execution of unauthorized commands within the context of the victim’s browser session. This vulnerability primarily affects web applications relying on CacheCloud for caching and cloud resource management, potentially exposing administrative interfaces or user dashboards to attack. The lack of vendor response and patch availability necessitates immediate defensive measures by users of the affected versions.

For European organizations, the impact of CVE-2025-15175 can be significant in environments where CacheCloud is deployed to manage caching and cloud resources. Exploitation could lead to compromised user sessions, unauthorized access to sensitive data, and potential lateral movement within internal networks if attackers leverage stolen credentials or session tokens. This risk is heightened in sectors such as finance, telecommunications, and critical infrastructure, where cloud management platforms are integral to operations. Additionally, the presence of a public exploit increases the likelihood of opportunistic attacks. While the vulnerability does not directly affect system availability, the integrity and confidentiality of data processed through CacheCloud-managed applications could be undermined, leading to reputational damage, regulatory non-compliance (e.g., GDPR breaches), and financial losses. European organizations relying on third-party or Chinese-origin cloud management tools should assess their exposure and prioritize mitigation to prevent exploitation.

Given the absence of an official patch, European organizations should implement the following specific mitigations: 1) Employ strict input validation and output encoding on all user-supplied data, particularly in the doAppList/appCommandAnalysis function or any exposed CacheCloud interfaces. 2) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting CacheCloud endpoints. 3) Restrict access to CacheCloud administrative interfaces using network segmentation, VPNs, or IP whitelisting to reduce exposure to external attackers. 4) Monitor web server and application logs for unusual requests or patterns indicative of XSS exploitation attempts. 5) Educate users and administrators about the risks of clicking untrusted links or interacting with suspicious content related to CacheCloud services. 6) Consider temporary disabling or isolating vulnerable CacheCloud instances until a vendor patch is released. 7) Engage with the vendor or community to track patch developments and apply updates promptly once available. 8) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities within CacheCloud deployments.
