Technical Analysis

CVE-2025-1138 is a medium-severity vulnerability identified in IBM InfoSphere Information Server version 11.7. The vulnerability is classified under CWE-548, which pertains to the exposure of information through directory listing. Specifically, the issue allows an authenticated user to access directory listings that reveal sensitive information about the server's file structure or contents. This exposure does not require user interaction and can be exploited remotely over the network with low attack complexity. The vulnerability impacts confidentiality by disclosing potentially sensitive information that could be leveraged by attackers to plan further attacks, such as identifying configuration files, scripts, or other resources that may contain credentials or system details. However, it does not directly affect the integrity or availability of the system. The CVSS 3.1 base score is 4.3, reflecting a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), and unchanged scope (S:U). No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability requires authentication, which limits exposure to users with some level of access, but the information disclosed could facilitate privilege escalation or other attacks if combined with additional vulnerabilities or insider threats.

Potential Impact

For European organizations using IBM InfoSphere Information Server 11.7, this vulnerability poses a moderate risk. InfoSphere is widely used in data integration and governance, often handling sensitive business and personal data. Exposure of directory listings could reveal internal file structures, configuration files, or other sensitive artifacts that attackers could use to map the environment and identify further attack vectors. This could lead to targeted attacks, data breaches, or unauthorized access to critical systems. Organizations in sectors such as finance, healthcare, telecommunications, and government, which heavily rely on data integration platforms, may be particularly impacted. The requirement for authenticated access reduces the risk from external attackers but raises concerns about insider threats or compromised credentials. Given the GDPR and other strict data protection regulations in Europe, any information disclosure that could lead to data breaches may result in regulatory penalties and reputational damage.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Restrict access to IBM InfoSphere Information Server to only trusted and necessary users, enforcing strict authentication and authorization controls. 2) Monitor and audit user activities to detect unusual access patterns that might indicate exploitation attempts. 3) Apply network segmentation and firewall rules to limit access to the InfoSphere server from untrusted networks. 4) Regularly review and harden server configurations to disable directory listing features where possible or restrict directory visibility to the minimum necessary. 5) Engage with IBM support to obtain patches or updates addressing this vulnerability as soon as they become available and prioritize their deployment. 6) Conduct internal penetration testing and vulnerability assessments focusing on InfoSphere environments to identify and remediate similar information disclosure issues. 7) Educate users with access about the risks of credential compromise and enforce strong password policies and multi-factor authentication to reduce the risk of unauthorized access.
