CVE-2025-2895 is a medium-severity vulnerability classified under CWE-80, which pertains to improper neutralization of script-related HTML tags in a web page, commonly known as a basic Cross-Site Scripting (XSS) vulnerability. This vulnerability affects multiple versions of IBM Cloud Pak System, specifically versions 2.3.3.6, 2.3.36 iFix1, 2.3.3.7, 2.3.3.7 iFix1, 2.3.4.0, 2.3.4.1, and 2.3.4.1 iFix1. The flaw allows a remote attacker with limited privileges (PR:L) and requiring user interaction (UI:R) to inject malicious HTML code into the web interface of the Cloud Pak System. When a victim views the injected content, the malicious HTML executes within the security context of the hosting site, potentially leading to unauthorized actions such as session hijacking, defacement, or redirection to malicious sites. The CVSS v3.1 score is 5.4, reflecting a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), and scope changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. The vulnerability does not impact availability but affects confidentiality and integrity to a limited extent. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability requires the attacker to have some level of privileges and the victim to interact with the malicious content, which somewhat limits the ease of exploitation but still poses a significant risk in environments where IBM Cloud Pak System is deployed and accessed by multiple users.

For European organizations, the impact of CVE-2025-2895 can be significant, particularly for enterprises relying on IBM Cloud Pak System for hybrid cloud management and orchestration. Successful exploitation could lead to unauthorized disclosure of sensitive information, session hijacking, or manipulation of user interactions within the Cloud Pak System interface. This could compromise the integrity of cloud management operations and potentially lead to further lateral movement within the network. Given the scope change indicated by the CVSS vector, the vulnerability could allow attackers to affect components beyond the initial vulnerable module, increasing the risk of broader compromise. Organizations in sectors such as finance, healthcare, manufacturing, and government, which often use IBM Cloud Pak System for critical infrastructure, could face operational disruptions and data breaches. The requirement for user interaction and privileges reduces the likelihood of mass exploitation but does not eliminate targeted attacks, especially in environments with multiple administrators or users with elevated permissions. Additionally, the lack of available patches increases the window of exposure, necessitating immediate mitigation efforts.

European organizations should implement the following specific mitigation strategies: 1) Restrict access to the IBM Cloud Pak System interface to trusted networks and users by enforcing strict network segmentation and access controls. 2) Implement robust user privilege management to minimize the number of users with elevated permissions capable of injecting malicious content. 3) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious HTML or script injections targeting the Cloud Pak System interface. 4) Educate users and administrators about the risks of interacting with untrusted or unexpected content within the Cloud Pak System UI to reduce the likelihood of successful exploitation via social engineering. 5) Monitor logs and user activities for unusual behavior indicative of attempted exploitation or injection attacks. 6) Engage with IBM support to obtain any available patches or workarounds as soon as they are released and prioritize timely application of these updates. 7) Consider deploying Content Security Policy (CSP) headers if configurable within the Cloud Pak System environment to restrict the execution of unauthorized scripts. 8) Conduct regular security assessments and penetration tests focusing on the Cloud Pak System to identify and remediate potential injection points proactively.
