CVE-2025-36131: 
IBM Db2 vulnerability analysis and mitigation

CVE-2025-36131 is a security vulnerability discovered in IBM Db2 versions 11.1.0 through 11.1.4.7, 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (including Db2 Connect Server). The vulnerability was disclosed on November 7, 2025, and involves the exposure of user credentials through the clpplus command, which could potentially be accessed by unauthorized parties with physical system access (IBM Security Bulletin).

The vulnerability is classified with CWE-359 (Exposure of Private Personal Information to an Unauthorized Actor) and has received a CVSS v3.1 Base Score of 4.6 (Medium) with the vector string CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. The issue specifically occurs when using the '-nw' (no windows) option with the clpplus command, which exposes user credentials to the terminal (IBM Security Bulletin).

The vulnerability allows unauthorized parties with physical access to the system to obtain user credentials displayed in the terminal. This exposure could potentially lead to unauthorized access to sensitive database information and compromise system security (IBM Security Bulletin).

IBM has provided both a workaround and permanent fixes for this vulnerability. As a workaround, users should use the CLPPLUS tool with the standard 'clpplus' command without the '-nw' option. For permanent remediation, special builds containing interim fixes are available for download from Fix Central for versions V11.1.4 FP7, V11.5.9, V12.1.2, and V12.1.3. These can be applied to any affected level of the appropriate release (IBM Security Bulletin).
