CVE-2023-2883
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 · uneditedAuthorization Bypass Through User-Controlled Key vulnerability in CBOT Chatbot allows Authentication Abuse, Authentication Bypass. This issue affects Chatbot: before Core: v4.0.3.4 Panel: v4.0.3.7.
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.
dbcve analysis · moderate confidenceThe CBOT Chatbot has an authorization bypass vulnerability where user-controlled input is used to determine authorization keys or identifiers. This allows attackers to manipulate these keys to bypass authentication checks and gain unauthorized access to the system or other users' accounts.

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.
-
Check CBOT Core versionLocate the installed version of CBOT Core. This is typically found in the application admin panel under system information, in a version file within the installation directory, or via a command-line tool provided by CBOT. Common locations include a config file or the application's main executable metadata.Affected if The installed CBOT Core version is lower than 4.0.3.4
-
Check CBOT Panel versionLocate the installed version of CBOT Panel. Access the Panel's admin interface, check the about page, or examine version information in the installation directory. The version may also be displayed in the web interface footer or system settings.Affected if The installed CBOT Panel version is lower than 4.0.3.7
-
Verify authorization logic exposureInspect the application's authorization mechanism to determine if user-supplied input (such as URL parameters, cookies, headers, or form fields) is being used to construct or influence authentication tokens, session identifiers, or access control decisions. Review code or configuration related to authentication and authorization flows.Affected if User-controlled input is directly used to determine authorization keys or session identifiers without proper validation
You are affected if CBOT Core is below version 4.0.3.4 or CBOT Panel is below version 4.0.3.7, and the application uses user input to determine authorization credentials.

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.
dbcve · scoped4.0.3.44.0.3.7
Upgrade CBOT Chatbot to Core v4.0.3.4 or later and Panel v4.0.3.7 or later to resolve the authorization bypass. Review authorization logic throughout the application to ensure user input cannot influence access control decisions.
Cbot Core: 4.0.3.4+ | Cbot Panel: 4.0.3.7+
- Upgrade Cbot Core to version 4.0.3.4 or later
- Upgrade Cbot Panel to version 4.0.3.7 or later
- After upgrading, verify that the authorization bypass vulnerability is resolved by testing user access controls
