Mailenable : Security Vulnerabilities, CVEs, CVSS score >= 8

Authenticated mail users, under specific circumstances, could add files with unsanitized content in public folders where the IIS user had permission to access. That action, could lead an attacker to store arbitrary code on that files and execute RCE commands.

MailEnable Enterprise Premium 10.23 did not use appropriate access control checks in a number of areas. As a result, it was possible to perform a number of actions, when logged in as a user, that that user should not have had permission to perform. It was also possible to gain access to areas within the application for which the accounts used were supposed to have insufficient access.

MailEnable Enterprise Premium 10.23 was vulnerable to multiple directory traversal issues, with which authenticated users could add, remove, or potentially read files in arbitrary folders accessible by the IIS user. This could lead to reading other users' credentials including those of SYSADMIN accounts, reading other users' emails, or adding emails or files to other users' accounts.

MailEnable Enterprise Premium 10.23 was vulnerable to XML External Entity Injection (XXE) attacks that could be exploited by an unauthenticated user. It was possible for an attacker to use a vulnerability in the configuration of the XML processor to read any file on the host system. Because all credentials were stored in a cleartext file, it was possible to steal all users' credentials (including the highest privileged users).

MailEnable before 8.60 allows XXE via an XML document in the request.aspx Options parameter.

MailEnable before 8.60 allows Privilege Escalation because admin accounts could be created as a consequence of %0A mishandling in AUTH.TAB after a password-change request.

MailEnable before 8.60 allows Directory Traversal for reading the messages of other users, uploading files, and deleting files because "/../" and "/.. /" are mishandled.

The IMAP service (MEIMAPS.exe) in MailEnable Professional Edition and Enterprise Edition 3.13 and earlier allows remote attackers to cause a denial of service (crash) via (1) SEARCH and (2) APPEND commands without required arguments, which triggers a NULL pointer dereference.

Multiple buffer overflows in the IMAP service (MEIMAPS.EXE) in MailEnable Professional Edition and Enterprise Edition 3.13 and earlier allow remote authenticated attackers to execute arbitrary code via long arguments to the (1) FETCH, (2) EXAMINE, and (3) UNSUBSCRIBE commands.

Stack-based buffer overflow in the IMAP service in MailEnable Enterprise and Professional Editions 2.37 and earlier allows remote authenticated users to execute arbitrary code via a long argument to the APPEND command. NOTE: this is probably different than CVE-2006-6423.

Unspecified vulnerability in a cryptographic feature in MailEnable Standard Edition before 1.93, Professional Edition before 1.73, and Enterprise Edition before 1.21 leads to "weakened authentication security" with unknown impact and attack vectors. NOTE: due to lack of details, it is not clear whether this is the same as CVE-2006-1792.

Stack-based buffer overflow in the POP service in MailEnable Standard 1.98 and earlier; Professional 1.84, and 2.35 and earlier; and Enterprise 1.41, and 2.35 and earlier before ME-10026 allows remote attackers to execute arbitrary code via a long argument to the PASS command.

Stack-based buffer overflow in the IMAP service for MailEnable Professional and Enterprise Edition 2.0 through 2.35, Professional Edition 1.6 through 1.84, and Enterprise Edition 1.1 through 1.41 allows remote attackers to execute arbitrary code via a pre-authentication command followed by a crafted parameter and a long string, as addressed by the ME-10025 hotfix.

The NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to (1) execute arbitrary code via unspecified vectors involving crafted base64 encoded NTLM Type 3 messages, or (2) cause a denial of service via crafted base64 encoded NTLM Type 1 messages, which trigger a buffer over-read.

Buffer overflow in NTLM authentication in MailEnable Professional 2.0 and Enterprise 2.0 allows remote attackers to execute arbitrary code via "the signature field of NTLM Type 1 messages".

Unspecified vulnerability in the POP service in MailEnable Standard Edition before 1.94, Professional Edition before 1.74, and Enterprise Edition before 1.22 has unknown attack vectors and impact related to "authentication exploits". NOTE: this is a different set of affected versions, and probably a different vulnerability than CVE-2006-1337.

Unknown vulnerability in the HTTPMail service in MailEnable Professional before 1.6 has unknown impact and attack vectors.

Buffer overflow in MailEnable Imapd (MEIMAP.exe) allows remote attackers to execute arbitrary code via a long LOGIN command.
