Aspera Faspex: Weak Password Requirements
CVE-2023-35907 is a critical-severity weak password requirements vulnerability in Aspera Faspex from IBM, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Aspera Faspex versions: 5.0.0 through 5.0.10. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.

Official description
IBM Aspera Faspex 5.0.0 through 5.0.10 does not require that users should have strong passwords by default, which makes it easier for attackers to compromise user accounts.

The underlying weakness: Weak Password Requirements
The product does not require that users should have strong passwords.
How developers prevent this class of flaw
- Consider a second authentication factor beyond the password, which prevents the password from being a single point of failure. See CWE-308 for further information.
- Consider implementing a password complexity meter to inform users when a chosen password meets the required attributes.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
