CVE-2025-11884 is a stored Cross-site Scripting (XSS) vulnerability identified in OpenText's Universal Configuration Management Database (uCMDB) version 24.4. The vulnerability stems from improper neutralization of input during web page generation, classified under CWE-79. Specifically, an attacker who already possesses high-level access privileges to the uCMDB can create or update data entries containing malicious scripts. These scripts are then stored and rendered in the application's web interface, potentially executing in the context of other users viewing the affected pages. The vulnerability does not require user interaction to trigger once the malicious payload is stored, but exploitation complexity is high because it requires elevated privileges (limited privileges) and no direct user interaction. The CVSS v4.0 base score is 2.3, reflecting low impact on confidentiality, integrity, and availability, with network attack vector and high attack complexity. No known exploits have been reported in the wild as of the publication date. The vulnerability could allow attackers to perform actions such as session hijacking, defacement, or redirecting users to malicious sites, but only within the scope of users who access the compromised data in uCMDB. Given uCMDB's role in IT asset and configuration management, exploitation could indirectly affect IT operations and security monitoring if attackers manipulate configuration data or inject misleading information. The vulnerability highlights the importance of proper input validation and output encoding in web applications, especially those managing critical enterprise infrastructure data.

For European organizations, the impact of CVE-2025-11884 is primarily related to the integrity and confidentiality of IT management data within OpenText uCMDB environments. Since uCMDB is used for configuration and asset management, malicious script injection could lead to misleading or corrupted configuration data, potentially disrupting IT operations or security monitoring. Attackers with high-level access could leverage this vulnerability to execute persistent XSS attacks, potentially hijacking sessions or performing unauthorized actions within the uCMDB interface. However, the low CVSS score and requirement for elevated privileges limit the scope and ease of exploitation. Organizations with large-scale IT infrastructure relying on uCMDB for configuration management may face operational risks if attackers manipulate configuration data or inject malicious content that affects administrators or security personnel. The vulnerability could also be used as a foothold for further attacks within the enterprise network if combined with other vulnerabilities or misconfigurations. Overall, while the direct impact is limited, the potential for indirect operational disruption and data integrity compromise makes this vulnerability relevant for European enterprises with critical IT management dependencies on OpenText uCMDB.

1. Apply official patches or updates from OpenText as soon as they become available to address this vulnerability. 2. Restrict high-level access to uCMDB strictly to trusted administrators and implement the principle of least privilege to minimize the number of users who can create or update data. 3. Implement strong input validation and output encoding on all user-supplied data within uCMDB to prevent injection of malicious scripts. 4. Conduct regular security audits and code reviews focusing on web interface components that render user-generated content. 5. Monitor logs and user activity within uCMDB for unusual or unauthorized data modifications that could indicate exploitation attempts. 6. Educate administrators about the risks of stored XSS and encourage cautious handling of configuration data inputs. 7. Consider deploying Web Application Firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting uCMDB interfaces. 8. Isolate uCMDB management interfaces within secure network segments to reduce exposure to external attackers. 9. Maintain up-to-date backups of configuration data to enable recovery in case of data tampering. 10. Coordinate with OpenText support for guidance and best practices specific to uCMDB security hardening.
