Detailsinfo

A vulnerability was found in MailEnable up to 10.53. It has been classified as critical. This affects some unknown processing in the library MEAISO.DLL. The manipulation with an unknown input leads to a uncontrolled search path vulnerability. CWE is classifying the issue as CWE-427.

This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
