CVE-2025-15051 is a cross-site scripting (XSS) vulnerability classified under CWE-79 that affects IBM QRadar SIEM versions 7.5.0 through 7.5.0 Update Package 14. The vulnerability arises from improper neutralization of input during web page generation in the QRadar web user interface. Specifically, it allows authenticated users with limited privileges to embed arbitrary JavaScript code into the web UI. This injected code can manipulate the UI's behavior, potentially enabling attackers to execute malicious scripts in the context of other users' browsers who access the compromised interface. The vulnerability requires the attacker to have some level of privileges (PR:L) and user interaction (UI:R), such as clicking a crafted link or interacting with a manipulated page. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The CVSS v3.1 base score is 5.4, indicating medium severity, with impacts on confidentiality and integrity but no direct impact on availability. No public exploits are currently known, and IBM has not yet published patches. The vulnerability could be leveraged to steal session tokens, manipulate displayed data, or perform actions on behalf of other users within the SIEM environment, potentially undermining the reliability of security monitoring and incident response activities.

The primary impact of CVE-2025-15051 is on the confidentiality and integrity of data within IBM QRadar SIEM environments. Successful exploitation could allow attackers to execute arbitrary JavaScript in the context of the SIEM web interface, potentially leading to session hijacking, unauthorized actions, or manipulation of security event data. This undermines trust in the SIEM's monitoring and alerting capabilities, which are critical for organizational security posture. While availability is not directly affected, the integrity compromise can delay or mislead incident response efforts. Organizations relying heavily on QRadar for security analytics and compliance reporting are at risk of data exposure or operational disruption. Since exploitation requires authenticated access and user interaction, the threat is somewhat mitigated but still significant in environments with multiple users or less restrictive access controls. The lack of known exploits reduces immediate risk but does not eliminate the potential for targeted attacks, especially by insiders or advanced threat actors.

To mitigate CVE-2025-15051, organizations should immediately review and restrict user privileges within IBM QRadar SIEM, ensuring that only trusted users have access to the web interface, especially those with permissions that could exploit this vulnerability. Implement strict input validation and sanitization on any user-supplied data fields within the SIEM interface where possible. Monitor user activity logs for unusual behavior indicative of attempted XSS exploitation. Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting QRadar interfaces. Until IBM releases an official patch, consider isolating the QRadar management console from less trusted networks and users to reduce exposure. Educate users about the risks of interacting with untrusted links or inputs within the SIEM environment. Regularly check IBM security advisories for updates or patches addressing this vulnerability and apply them promptly once available. Additionally, conduct penetration testing focused on web interface vulnerabilities to identify and remediate similar issues proactively.
