CVE-2022-31769

Vulnerability

IBM Spectrum Copy Data Management versions 2.2.0.0 through 2.2.15.0 expose product configuration information stored in a PostgreSQL database to remote, unauthenticated attackers. This information disclosure arises from unnecessary open ports that allow querying the database without proper access controls [1].

Exploitation

An attacker with network access to the vulnerable IBM Spectrum Copy Data Management instance can send specially crafted queries to the exposed PostgreSQL port. No authentication or user interaction is required. The attacker simply needs to identify the open database port and issue queries that retrieve configuration data [1].

Impact

Successful exploitation reveals product configuration details, which may include internal settings, network topology, or other metadata. While the disclosed information is limited (CVSS Confidentiality impact: Low), it can be leveraged to plan more sophisticated attacks against the system, such as credential theft or privilege escalation [1].

Mitigation

IBM has released fixes as part of the standard patch cycle. Administrators should upgrade to a version later than 2.2.15.0. Instructions for obtaining the fix are provided in the IBM Security Bulletin [1]. As a workaround, restrict network access to the PostgreSQL port (default 5432) using firewall rules or network segmentation to limit exposure to trusted hosts only.
