CVE-2026-90457
Product Credential Store Insecure Password Hash Storage and Improper Access Control
Description

The administrative password is hashed using a comparatively weak, fast algorithm for the credential store backing one authentication path, and the file containing that hash is written with permissions allowing it to be read by any local user. This is inconsistent with a separate, stronger hashing algorithm used for the same password on another authentication path. A party able to read this file, including a local user or a party with access to a configuration backup, could feasibly recover the underlying password through offline computation, compromising the administrative credential across every path that accepts it.

Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 4.0 MEDIUM 7d14cffa-0d7d-4270-9dc0-52cabd5a23a6
CVSS 4.0 MEDIUM [email protected]
Solution
Strengthen password hashing and restrict file access for credential storage.
  • Use a strong, slow hashing algorithm for all passwords.
  • Restrict file permissions to only authorized personnel.
  • Implement secure credential storage mechanisms.
  • Regularly audit access controls.
