CVE-2023-39903 Detail


An issue was discovered in Fujitsu Software Infrastructure Manager (ISM) before The ismsnap component (in this specific case at /var/log/fujitsu/ServerViewSuite/ism/FirmwareManagement/FirmwareManagement.log) allows insecure collection and storage of authorization credentials in cleartext. That occurs when users perform any ISM Firmware Repository Address setup test (Test the Connection), or regularly authorize against an already configured remote firmware repository site, as set up in ISM Firmware Repository Address. A privileged attacker is therefore able to potentially gather the associated ismsnap maintenance data, in the same manner as a trusted party allowed to export ismsnap data from ISM. The preconditions for an ISM installation to be generally vulnerable are that the Download Firmware (Firmware Repository Server) function is enabled and configured, and that the character \ (backslash) is used in a user credential (i.e., user/ID or password) of the remote proxy host / firmware repository server. NOTE: this may overlap CVE-2023-39379.


CVSS 3.x Severity and Metrics:

Base Score:  5.0 MEDIUM
Vector:  CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N

Nist CVSS score does not match with CNA score
Base Score:  5.9 MEDIUM
Vector:  CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
