2DescriptionNVD
mpGabinet is vulnerable to Remote Command Execution. An authorized user with access to the application and direct access to the backend database can achieve system command execution by uploading an attachment and modifying its storage path in the database to reference an attacker-controlled remote network resource. Alternatively, it is possible to use a previously uploaded file and change its reference. When the application processes the attachment, and a user tries to open it, the referenced resource is executed by the system. Critically, this vulnerability can be exploited by any unauthenticated attacker by chaining it with CVE-2026-40550 and CVE-2026-40551, which allows obtaining database access, and logging onto any account.
This issue affects mpGabinet version 23.12.19 and below.
AnalysisAI
Remote command execution in mpGabinet 23.12.19 and below allows authenticated database administrators or unauthenticated attackers (via chained exploitation of CVE-2026-40550 and CVE-2026-40551) to achieve system command execution by manipulating attachment storage paths in the database to reference attacker-controlled resources that execute when users open the files. The vulnerability requires direct database access and user interaction to trigger execution, but becomes unauthenticated when chained with companion CVE vulnerabilities that grant database and application access.
