mpGabinet EUVD-2026-26044

Local access to the system running mpGabinet is required (either SSH login, console access, or prior arbitrary code execution). No special application configuration or feature flag is needed-the vulnerability exists in default deployments. The attacker must be able to inspect process memory (using debuggers, /proc/PID/mem on Linux, memory dump tools on Windows); this requires either running as the same user, running as root/SYSTEM, or bypassing OS memory access controls. The database credentials are stored in application memory during normal operation and are extractable by standard tools without requiring kernel exploits. Exploitation is limited to systems where: (1) process memory inspection is not blocked by OS-level restrictions (e.g., kernel hardening, SELinux, AppArmor in enforcing mode); (2) the attacker has local system access; (3) the database is reachable from the compromised system (usually true for backend server, may be blocked by network segmentation).

CVSS 6.9 with AV:L (local attack vector) and PR:N (no privileges required) indicates a local privilege escalation path with high confidentiality impact (VC:H). The attack requires initial local access to the system but no authentication to the application itself. The real-world risk depends on three factors: (1) whether unprivileged local users can easily access process memory on the target OS (true on most Linux/Windows without hardening); (2) whether the environment is shared-hosting or multi-tenant; (3) whether database credentials are stored plaintext or merely obfuscated in memory. EPSS and KEV status are not provided; however, the straightforward nature of memory inspection (no exploit development needed, standard tools sufficient) and the high-value target (database administrative access) suggest moderate exploitation likelihood in multi-user or compromised environments. The limiting factor is local access requirement-this is not a network-remotely exploitable vulnerability. For single-user or air-gapped deployments, risk is lower; for cloud VMs or shared infrastructure, risk is elevated.

A contractor gains SSH access to a shared server hosting mpGabinet to perform legitimate maintenance. The contractor runs 'gdb' or 'strings' against the running mpGabinet process and extracts the database admin password from memory. Using those credentials, the contractor connects directly to the backend database (bypassing application logging) and modifies user accounts, exports sensitive data, or drops tables to sabotage operations.
