For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IPSwitch IMail List Mailer. Authentication is not required to exploit this vulnerability. The specific flaw exists within imailsrv.exe which is invoked to handle messages sent to the imailsrv. When a message contains multiple "Reply-To:" headers the imailsrv.exe process concatenates these into a single fixed length buffer on the stack. No validation of the data or data length is done. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user. - -- Vendor Response: Ipswitch states: Update to the latest version 11.02 - -- Disclosure Timeline: 2010-06-08 - Vulnerability reported to vendor 2010-07-15 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.

Authentication might be required to exploit this vulnerability. The specific flaw exists within imailsrv.exe which is invoked to handle messages sent to the imailsrv. When a message subject contains a "?Q?" operator the string following that sequence is copied to a local stack buffer. No validation of the data or data length is done. In order to reach this code path a mailing list must be password protected (authentication required) or have previously had a password configured (no authentication required). A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user. - -- Vendor Response: Ipswitch states: Update to the latest version 11.02 - -- Disclosure Timeline: 2010-06-08 - Vulnerability reported to vendor 2010-07-15 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.

For further product information on the TippingPoint IPS, visit: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IPSwitch IMail. Authentication is not required to exploit this vulnerability. The specific flaw exists within SMTPDLL.dll (called by queuemgr.exe). When handling a message queued for remote delivery user supplied data can be used to specify additional format specifiers to a vsprintf call. This can be accomplished by providing a specially crafted -NOTIFY argument to the SMTP "RCPT TO:" argument. Additionally, the destination buffer supplied to vsprintf is a local stack buffer and can also be overflowed with a large -NOTIFY argument. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user. - -- Vendor Response: Ipswitch states: Update to the latest version 11.02 - -- Disclosure Timeline: 2010-06-08 - Vulnerability reported to vendor 2010-07-15 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by: * Anonymous - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.
