CVE-2024-3781
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 · uneditedCommand injection vulnerability in the operating system. Improper neutralisation of special elements in Active Directory integration allows the intended command to be modified when sent to a downstream component in WBSAirback 21.02.04.
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 confidenceCommand injection vulnerability in WBSAirback version 21.02.04 where improper neutralization of special elements in the Active Directory integration module allows attackers to modify the intended OS command before it is executed by a downstream component. The lack of input sanitization on Active Directory-related parameters permits injection of arbitrary shell commands.

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 WBSAirback installationLocate WBSAirback on the system. Common locations may include /opt/wbsairback, /usr/local/wbsairback, or check system packages. Look for the wbsairback service or daemon.Affected if WBSAirback software is installed on the system
-
Verify installed versionCheck the WBSAirback version. This may be done via package manager (dpkg -l wbsairback or rpm -qi wbsairback), the web interface version display, or a version file in the installation directory.Affected if The installed version is exactly 21.02.04
-
Confirm Active Directory integration is configuredExamine WBSAirback configuration for Active Directory or LDAP integration settings. Look for AD domain, LDAP server, or directory service configuration parameters in the web interface or configuration files.Affected if Active Directory integration module is enabled and configured with AD domain/connection parameters
-
Inspect AD parameters for injection pointsReview the AD integration configuration parameters, particularly those related to AD server hostname, domain name, bind DN, or user filters. These are the fields where command injection could occur.Affected if AD integration is using parameters without visible input validation or sanitization
You are affected if WBSAirback version 21.02.04 is installed AND the Active Directory integration module is configured and uses unsanitized input fields.
Generated from the published advisory. Verify against your own configuration.
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 dataImplement strict input validation and sanitization on all Active Directory integration parameters, preferably using parameterized APIs or avoiding shell command execution entirely. If shell commands are unavoidable, employ allowlist validation and proper escaping mechanisms for special characters.
