Detailsinfo

A vulnerability, which was classified as critical, has been found in MailEnable up to 10.53. Affected by this issue is an unknown code in the library MEAIAM.DLL. The manipulation with an unknown input leads to a uncontrolled search path vulnerability. Using CWE to declare the problem leads to CWE-427.

Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 MEAIAM.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 MEAIAM.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.
