CVE-2025-2141 is a cross-site scripting (XSS) vulnerability identified in 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 due to improper neutralization of input during web page generation (CWE-79), allowing an authenticated user to inject arbitrary JavaScript code into the web user interface (Web UI). This malicious script can alter the intended functionality of the interface and potentially lead to the disclosure of sensitive information such as user credentials within a trusted session. The vulnerability requires the attacker to have valid authentication credentials and some user interaction (e.g., visiting a crafted page or triggering a specific UI action). The CVSS v3.1 base score is 6.1, reflecting a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction needed, and a scope change indicating that the vulnerability affects components beyond the initially vulnerable system. The impact primarily affects confidentiality and integrity, with no direct impact on availability. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability is significant because the TS7700 is a critical storage virtualization platform used in enterprise environments to manage large-scale storage resources, and compromise of its management interface could lead to unauthorized access or manipulation of storage configurations and sensitive data.

For European organizations, the impact of this vulnerability could be substantial, especially for enterprises relying on IBM TS7700 systems for their storage virtualization needs, such as financial institutions, healthcare providers, and large manufacturing firms. Exploitation could lead to credential theft within trusted sessions, enabling attackers to escalate privileges or move laterally within the network. This could result in unauthorized access to sensitive storage management functions, data leakage, or manipulation of storage configurations, potentially disrupting business operations or violating data protection regulations such as GDPR. Given that the vulnerability requires authenticated access, insider threats or compromised credentials pose a significant risk. The medium severity rating suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, the consequences of exploitation could still be damaging in environments where the TS7700 is a critical component of the IT infrastructure.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Restrict access to the TS7700 Web UI to trusted administrative networks using network segmentation and firewall rules to minimize exposure. 2) Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 3) Monitor and audit user activities on the TS7700 management interface to detect anomalous behavior indicative of exploitation attempts. 4) Apply strict input validation and sanitization policies on any custom integrations or scripts interacting with the TS7700 Web UI, if applicable. 5) Regularly update and patch the TS7700 systems as IBM releases security updates addressing this vulnerability. 6) Educate administrators about the risks of XSS and the importance of not executing untrusted scripts or clicking on suspicious links within the management interface. 7) Consider deploying web application firewalls (WAFs) that can detect and block XSS payloads targeting the TS7700 Web UI. These targeted mitigations go beyond generic advice by focusing on access control, authentication hardening, monitoring, and proactive defense tailored to the TS7700 environment.
