CVE-2025-2141 is a cross-site scripting (XSS) vulnerability identified in the IBM System Storage Virtualization Engine TS7700, specifically affecting versions 8.60.0.115 of the 3957 VED, 3948 VED, and 3948 VEF models. The vulnerability arises from improper neutralization of input during web page generation (CWE-79), allowing an authenticated user to inject arbitrary JavaScript code into the web user interface. This injected script can alter the intended functionality of the web UI, potentially leading to the disclosure of sensitive information such as user credentials within a trusted session. The vulnerability requires the attacker to have authenticated access to the system’s web interface, and user interaction is necessary to trigger the malicious script. The CVSS v3.1 base score is 6.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but user interaction needed, with a scope change and limited confidentiality and integrity impact but no availability impact. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because the TS7700 is a critical storage virtualization platform used in enterprise environments to manage large-scale storage systems, and compromise of its management interface could lead to unauthorized access or manipulation of storage operations.

For European organizations, the impact of this vulnerability could be substantial, particularly for enterprises relying on IBM TS7700 systems for critical storage virtualization tasks. Successful exploitation could lead to credential theft within trusted sessions, enabling attackers to escalate privileges or move laterally within the network. This could compromise the confidentiality and integrity of stored data and management operations. Given the TS7700’s role in data center storage infrastructure, disruption or unauthorized access could affect business continuity and data protection compliance, including GDPR requirements. The vulnerability’s requirement for authenticated access limits exposure to internal or trusted users, but insider threats or compromised credentials could be leveraged. Additionally, the scope change in CVSS indicates potential for broader impact beyond the initially affected component, increasing risk in interconnected environments. European organizations with stringent data protection mandates must consider the risk of data leakage and unauthorized access resulting from this XSS flaw.

To mitigate this vulnerability, European organizations should first ensure strict access controls and monitoring on the TS7700 management interfaces, limiting authenticated user access to trusted personnel only. Implement multi-factor authentication (MFA) to reduce the risk of credential compromise. Since no patches are currently linked, organizations should apply any forthcoming IBM security updates promptly once available. In the interim, disable or restrict web UI access where feasible, or isolate management interfaces on dedicated, secure network segments with strict firewall rules. Conduct regular audits of user activity and session logs to detect anomalous behavior indicative of exploitation attempts. Employ web application firewalls (WAFs) capable of detecting and blocking XSS payloads targeting the TS7700 UI. Additionally, educate administrators about the risks of XSS and the importance of not executing suspicious links or scripts within the management console. Finally, review and harden input validation and sanitization mechanisms in custom integrations or scripts interacting with the TS7700 UI.
