Summary
MailEnable versions prior to 10.54 contain a reflected cross-site scripting (XSS) vulnerability in the Added parameter of /Mondo/lang/sys/Forms/MAI/AddRecipientsResult.aspx. The Added value is not properly sanitized when processed via a GET request and is reflected in the response, allowing an attacker to break out of existing markup and inject arbitrary script. A remote attacker can supply a crafted payload that closes an existing HTML list element, inserts attacker-controlled JavaScript, and comments out remaining code, leading to script execution in a victim's browser when the victim visits a malicious link.
Risk Assessment
Successful exploitation can redirect victims to malicious sites, steal non-HttpOnly cookies, inject arbitrary HTML or CSS, and perform actions as the authenticated user. This poses a risk to organizations using MailEnable, especially if users have access to the administrative panel.
Recommendation
Update MailEnable to version 10.54 or later. Additionally, consider implementing security headers (CSP) and training users to avoid suspicious links.

Cross Site Scripting (XSS) vulnerability in MailEnable before version 10 allows a remote attacker to execute arbitrary code via the failure.aspx component.
- CVE-2025-34428High
In MailEnable versions prior to 10.54, user and administrative passwords are stored in cleartext within AUTH.SAV with overly permissive filesystem access. A local authenticated user with read access to this file can recover all user passwords and super-admin credentials.
- CVE-2025-34427High
In MailEnable versions prior to 10.54, user and administrative passwords are stored in cleartext within AUTH.TAB with overly permissive filesystem access. A local authenticated user with read access to this file can recover all user passwords and super-admin credentials.
- CVE-2025-34424High
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 MEAIDP.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 MEAIDP.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.
- CVE-2025-34423High
MailEnable versions prior to 10.54 contain an unsafe DLL loading vulnerability that can lead to local arbitrary code execution. The administrative executable attempts to load MEAIAU.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 MEAIAU.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.
- CVE-2025-34422High
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 MEAIPC.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 MEAIPC.DLL, which is then loaded on execution, resulting in attacker-controlled code running with the privileges of the process.
- CVE-2025-34421High
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.
- CVE-2025-34420High
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.
- CVE-2025-34419High
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 MEAISM.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 MEAISM.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.
- CVE-2025-34418High
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 MEAIMF.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 MEAIMF.DLL, which is then loaded when the executable starts, resulting in execution of attacker-controlled code with the privileges of the process.
