Mailenable : Security Vulnerabilities, CVEs, CVSS score >= 4

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 was vulnerable to stored and reflected cross-site scripting (XSS) attacks. Because the session cookie did not use the HttpOnly flag, it was possible to hijack the session cookie by exploiting this vulnerability.

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).

In MailEnable Enterprise Premium 10.23, the potential cross-site request forgery (CSRF) protection mechanism was not implemented correctly and it was possible to bypass it by removing the anti-CSRF token parameter from the request. This could allow an attacker to manipulate a user into unwittingly performing actions within the application (such as sending email, adding contacts, or changing settings) on behalf of the attacker.

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

MailEnable before 8.60 allows Stored XSS via malformed use of "<img/src" with no ">" character in the body of an e-mail message.

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.

Multiple cross-site scripting (XSS) vulnerabilities in MailEnable Enterprise 6.5 allow remote attackers to inject arbitrary web script or HTML via the (1) From, (2) To, or (3) Subject header or (4) body in an SMTP e-mail message.

Cross-site scripting (XSS) vulnerability in ForgottenPassword.aspx in MailEnable Professional, Enterprise, and Premium 4.26 and earlier, 5.x before 5.53, and 6.x before 6.03 allows remote attackers to inject arbitrary web script or HTML via the Username parameter.

The SMTP service (MESMTPC.exe) in MailEnable 3.x and 4.25 does not properly perform a length check, which allows remote attackers to cause a denial of service (crash) via a long (1) email address in the MAIL FROM command, or (2) domain name in the RCPT TO command, which triggers an "unhandled invalid parameter error."

MailEnable Professional 3.5.2 and Enterprise 3.52 allow remote attackers to cause a denial of service (crash) via multiple IMAP connection requests to the same folder.

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.

Multiple unspecified vulnerabilities in the SMTP service in MailEnable Standard Edition 1.x, Professional Edition 3.x and earlier, and Enterprise Edition 3.x and earlier allow remote attackers to cause a denial of service (crash) via crafted (1) EXPN or (2) VRFY 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.

The NTLM_UnPack_Type3 function in MENTLM.dll in MailEnable Professional 2.35 and earlier allows remote attackers to cause a denial of service (application crash) via certain base64-encoded data following an AUTHENTICATE NTLM command to the imap port (143/tcp), which results in an out-of-bounds read.

Cross-site request forgery (CSRF) vulnerability in MailEnable Professional before 2.37 allows remote attackers to modify arbitrary configurations and perform unauthorized actions as arbitrary users via a link or IMG tag.

Multiple cross-site scripting (XSS) vulnerabilities in MailEnable Professional before 2.37 allow remote attackers to inject arbitrary Javascript script via (1) e-mail messages and (2) the ID parameter to (a) right.asp, (b) Forms/MAI/list.asp, and (c) Forms/VCF/list.asp in mewebmail/base/default/lang/EN/.

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.

MailEnable Professional before 1.78 provides a cleartext user password when an administrator edits the user's settings, which allows remote authenticated administrators to obtain sensitive information by viewing the HTML source.

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.

The IMAP service for MailEnable Professional and Enterprise Edition 2.0 through 2.34, Professional Edition 1.6 through 1.83, and Enterprise Edition 1.1 through 1.40 allows remote attackers to cause a denial of service (crash) via unspecified vectors that trigger a null pointer dereference, as addressed by the ME-10023 hotfix, and a different issue than CVE-2006-6423. NOTE: some details were obtained from third party information.
