CVE-2025-2896 is a medium-severity cross-site scripting (XSS) vulnerability affecting IBM Planning Analytics Local versions 2.0 and 2.1. 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 application within the trusted session context. Exploitation requires the attacker to have valid credentials and perform some user interaction, such as submitting crafted input that is not properly sanitized. The vulnerability does not allow direct remote exploitation without authentication and user interaction but can lead to disclosure of sensitive information such as user credentials or session tokens within the affected session. The CVSS v3.1 base score is 4.8, reflecting network attack vector, low attack complexity, high privileges required, user interaction required, and partial impact on confidentiality and integrity but no impact on availability. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that remediation may still be pending or in progress. IBM Planning Analytics Local is an on-premises business analytics and planning software widely used for financial and operational planning, making this vulnerability relevant for organizations relying on this product for critical business functions.

For European organizations using IBM Planning Analytics Local 2.0 or 2.1, this vulnerability poses a risk of unauthorized script execution within authenticated sessions. Attackers with valid credentials could exploit this to steal session cookies, capture credentials, or manipulate the user interface to perform actions on behalf of legitimate users. This could lead to unauthorized access to sensitive financial and operational data, undermining data confidentiality and integrity. While the vulnerability does not directly impact system availability, the potential for credential theft and session hijacking could facilitate further attacks, including privilege escalation or lateral movement within the network. Given the critical nature of planning and analytics data, exploitation could result in financial loss, regulatory non-compliance (e.g., GDPR breaches due to data exposure), and reputational damage. The requirement for authentication and user interaction limits the attack surface but does not eliminate risk, especially in environments with many users or weak internal access controls.

To mitigate this vulnerability, European organizations should: 1) Immediately review and restrict user privileges to minimize the number of users with access to IBM Planning Analytics Local, enforcing the principle of least privilege. 2) Implement strict input validation and output encoding on all user-supplied data within the application, if customization or scripting is possible. 3) Monitor user activity logs for unusual behavior indicative of XSS exploitation attempts. 4) Apply any IBM-provided patches or updates as soon as they become available. 5) Employ web application firewalls (WAFs) with rules tailored to detect and block XSS payloads targeting the Planning Analytics Local interface. 6) Educate users on the risks of interacting with suspicious inputs or links within the application. 7) Consider network segmentation to isolate the Planning Analytics environment from broader corporate networks to limit lateral movement if exploitation occurs. 8) Conduct regular security assessments and penetration testing focusing on web interface vulnerabilities to proactively identify and remediate similar issues.
