Detailsinfo

A vulnerability, which was classified as critical, was found in MailEnable up to 10.53. This affects an unknown code block in the library MEAISP.DLL. The manipulation with an unknown input leads to a uncontrolled search path vulnerability. CWE is classifying the issue as CWE-427. The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors. 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 MEAISP.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 MEAISP.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.
