Buffer overflow in the IMAP service of TrueNorth Internet Anywhere (IA) eMailserver 5.3.4 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a long SEARCH argument.

SoftiaCom wMailServer 1.0 and 2.0 allows remote attackers to cause a denial of service (application crash) via a large TCP packet with a leading space, possibly triggering a buffer overflow.

Softiacom wMailserver 1.0 stores passwords in plaintext in the Darsite\MAILSRV\Admin key, which allows local users to gain administrator privileges.

Format string vulnerability in IMAP4 in IA eMailServer Corporate Edition 5.2.2 build 1051 allows remote attackers to cause a denial of service (application crash) via a LIST command with format string specifiers as the second argument.

The administration protocol for Kerio WinRoute Firewall 6.x up to 6.0.10, Personal Firewall 4.x up to 4.1.2, and MailServer up to 6.0.8 allows remote attackers to quickly obtain passwords that are 5 characters or less via brute force methods.

The administration protocol for Kerio WinRoute Firewall 6.x up to 6.0.10, Personal Firewall 4.x up to 4.1.2, and MailServer up to 6.0.8 allows remote attackers to cause a denial of service (CPU consumption) via certain attacks that force the product to "compute unexpected conditions" and "perform cryptographic operations."

Unknown vulnerability in WebMail in Kerio MailServer before 6.0.9 allows remote attackers to cause a denial of service (CPU consumption) via certain e-mail messages.

SQL injection vulnerability in (1) fdelmail.asp, (2) addressc.asp, and possibly (3) postmail.asp and (4) fmvmail.asp in CMailServer 5.2 allow remote attackers to inject arbitrary SQL commands and delete mail metadata or e-mail addresses of contacts via the indexOfMail parameter.

Kerio Winroute Firewall before 6.0.9, ServerFirewall before 1.0.1, and MailServer before 6.0.5, when installed on Windows based systems, do not modify the ACLs for critical files, which allows local users with Power Users privileges to modify programs, install malicious DLLs in the plug-ins folder, and modify XML files related to configuration.

Kerio Winroute Firewall before 6.0.7, ServerFirewall before 1.0.1, and MailServer before 6.0.5 use symmetric encryption for user passwords, which allows attackers to decrypt the user database and obtain the passwords by extracting the secret key from within the software.
