Summary

CVE-2023-35907 is a medium-severity Weak Password Requirements (CWE-521) vulnerability in Ibm Aspera Faspex. Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 24th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

IBM Aspera Faspex versions 5.0.0 through 5.0.10 are affected by CVE-2023-35907, a vulnerability stemming from the lack of a default requirement for strong passwords (CWE-521). This configuration weakness allows users to set weak passwords, rated with a CVSS v3.1 base score of 5.9 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating medium severity primarily due to high confidentiality impact.

Remote attackers with no privileges can exploit this over the network without user interaction, though it requires high attack complexity, likely involving brute-force attempts or password guessing against weak credentials. Successful exploitation enables compromise of user accounts, granting high-level access to confidential data within the Faspex environment.

IBM's security advisory at https://www.ibm.com/support/pages/node/7181814 provides details on mitigation, recommending enforcement of strong password policies to address the default configuration issue.
