CVE-2021-27616
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnder certain conditions, SAP Business One Hana Chef Cookbook, versions - 8.82, 9.0, 9.1, 9.2, 9.3, 10.0, used to install SAP Business One for SAP HANA, allows an attacker to exploit an insecure temporary backup path and to access information which would otherwise be restricted, resulting in Information Disclosure vulnerability highly impacting the confidentiality, integrity and availability of the application.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed SAP Business One Hana Chef Cookbook versionRun 'chef --version' or check the cookbook metadata in the chef repository for version informationAffected if Version equals 0.1.6, 0.1.7, or 0.1.19
-
Identify installed SAP Business One versionCheck the SAP Business One version through the SAP Business One client, server administration, or installation logsAffected if Version equals 8.82, 9.0, 9.1, 9.2, 9.3, or 10.0
-
Locate temporary backup path configurationExamine the Chef cookbook recipe files or configuration templates used during SAP Business One installation for temporary backup path settingsAffected if The configuration uses a world-writable or insecure temporary directory without proper access restrictions
-
Verify backup directory permissionsInspect the permissions on any temporary backup directories created during or after installation using file system inspection toolsAffected if The backup directory allows unauthorized access due to overly permissive file system permissions
A user is affected if they are running SAP Business One Hana Chef Cookbook version 0.1.6, 0.1.7, or 0.1.19, or SAP Business One versions 8.82 through 10.0, and the installation process uses an insecure temporary backup path accessible to unauthorized users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSecure the temporary backup path by implementing proper access controls, using secure temporary directories with restricted permissions, and ensuring backups are stored in protected locations with appropriate file system permissions.
