CVE-2025-2827: IBM Sterling File Gateway Sensitive Information Disclosure
IBM Sterling File Gateway is a powerful platform used for secure file transfer and integration. However, a newly discovered vulnerability could allow authenticated users to potentially gain access to sensitive system information. Let's dive into the details.
Vulnerability Details
- CVE ID: CVE-2025-2827
- Description: IBM Sterling File Gateway versions 6.0.0.0 through 6.1.2.6, and 6.2.0.0 through 6.2.0.4 could disclose sensitive installation directory information to an authenticated user. This information could be used in further attacks against the system.
- CVSS Score: 4.3 (Medium)
- CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
- CVSS Explanation: This vulnerability has a medium severity because it can be exploited over the network (AV:N) with low complexity (AC:L) and requires only low privileges (PR:L). The impact is limited to confidentiality (C:L), meaning an attacker can gain access to some sensitive information, but it does not affect integrity or availability. User interaction is not required (UI:N), and the scope is unchanged (S:U).
- Exploit Requirements: An attacker needs valid credentials to authenticate to the IBM Sterling File Gateway system.
- Affected Vendor: IBM
- Affected Product: Sterling File Gateway
- Affected Versions: 6.0.0.0 through 6.1.2.6, and 6.2.0.0 through 6.2.0.4
- CWE: CWE-548 - Exposure of Information Through Directory Listing
- CWE Explanation: CWE-548 occurs when a web server or application exposes a directory listing, revealing the structure and contents of directories. While not directly a directory listing, the vulnerability leads to exposing similar sensitive path information.

Exploitability & Real-World Risk
While the CVSS score is moderate, the real-world risk should not be underestimated. An attacker who gains access to sensitive installation directory information can use this knowledge to map out the system's architecture and potentially identify other vulnerabilities. This is often a crucial step in a multi-stage attack. For instance, knowing the location of specific configuration files could allow an attacker to target known vulnerabilities associated with those files or craft custom exploits.
Recommendations
IBM has likely released a fix for this vulnerability. Here are the steps to take:
- Apply the Latest Patches: Check the IBM support page (linked below) for the latest patches and updates for your version of Sterling File Gateway.
- Review Access Controls: Ensure that access controls are properly configured and that only authorized users have access to the system.
- Monitor System Logs: Regularly monitor system logs for any suspicious activity.
Technical Insight
The vulnerability likely stems from insufficient access control checks on certain API endpoints or functionalities within Sterling File Gateway. By manipulating requests, an authenticated user can trigger the disclosure of installation directory information that should be restricted. Further investigation is required for definitive confirmation pending a security advisory and patch release.
