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.

Buffer overflow in the Visnetic anti-virus plugin in Kerio MailServer before 6.5.0 might allow remote attackers to execute arbitrary code via unspecified vectors.

Kerio Personal Firewall (KPF) 2.1.5 allows local users to execute arbitrary code with SYSTEM privileges via the Load button in the Firewall Configuration Files option, which does not drop privileges before opening the file loading dialog box.

The STARTTLS implementation in Kerio Connect 7.1.4 build 2985 and MailServer 6.x does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411. NOTE: some of these details are obtained from third party information.

Multiple SQL injection vulnerabilities in Kerio Control Statistics in Kerio Control (formerly WinRoute Firewall) before 8.3.2 allow remote authenticated users to execute arbitrary SQL commands via the (1) x16 or (2) x17 parameter to print.php.

Kerio Connect 8.0.0 through 9.2.2, and Kerio Connect Client desktop application for Windows and Mac 9.2.0 through 9.2.2, when e-mail preview is enabled, allows remote attackers to conduct clickjacking attacks via a crafted e-mail message.

Kerio WinRoute Firewall before 6.0.9 uses information from PTR queries in response to A queries, which allows remote attackers to poison the DNS cache or cause a denial of service (connection loss).

Unspecified vulnerability in Kerio MailServer before 6.1.4 has unknown impact and remote attack vectors related to a "possible bypass of attachment filter."

Untrusted search path vulnerability in (1) WSAdminServer and (2) WSWebServer in Kerio WebSTAR (4D WebSTAR Server Suite) 5.4.2 and earlier allows local users with webstar privileges to gain root privileges via a malicious libucache.dylib helper library in the current working directory.

Multiple cross-site scripting (XSS) vulnerabilities in Kerio MailServer 5.6.3 allow remote attackers to insert arbitrary web script via (1) the addname parameter in the addacl module, or (2) the alias parameter in the domap module.

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.

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."

Kerio WinRoute Firewall 6.2.2 and earlier allows remote attackers to cause a denial of service (crash) via malformed DNS responses.

The FWDRV.SYS driver in Kerio Personal Firewall 4.1.1 and earlier allows remote attackers to cause a denial of service (CPU consumption and system freeze from infinite loop) via a (1) TCP, (2) UDP, or (3) ICMP packet with a zero length IP Option field.

Multiple unspecified vulnerabilities in Kerio WinRoute Firewall before 6.1.4 Patch 1 allow remote attackers to cause a denial of service via multiple unspecified vectors involving (1) long strings received from Active Directory and (2) the filtering of HTML.
