CVE-2025-34417 (GCVE-0-2025-34417)

Vulnerability from cvelistv5 – Published: 2025-12-10 16:09 – Updated: 2026-05-14 02:08

Title

MailEnable < 10.54 DLL Hijacking via Unsafe Loading of MEAISO.DLL

Summary

MailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability that can lead to local arbitrary code execution. The MailEnable administrative executable attempts to load MEAISO.DLL from its installation directory without sufficient integrity validation or a secure search order. A local attacker with write access to that directory can plant a malicious MEAISO.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.

Severity

8.5 (High)

The MailEnable administrative executable attempts to load MEAISO.DLL from its installation directory without sufficient integrity validation or a secure search order. A local attacker with write access to that directory can plant a malicious MEAISO.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
