TITLE

Ipswitch Collaboration component SMTP Format string processing vulnerability

DESCRIPTION

Format string vulnerability in the SMTP service in IMail Server 8.20 in Ipswitch Collaboration Suite (ICS) before 2.02 allows remote attackers to execute arbitrary code via format string specifiers to the (1) EXPN, (2) MAIL, (3) MAIL FROM, and (4) RCPT TO commands. This issue is due to a failure of the application to properly sanitize user-supplied input prior to including it in a format-specifier argument to a formatted printing function. This issue allows remote attackers to execute arbitrary machine code in the context of the affected application. TITLE: Ipswitch IMail Server IMAP and SMTP Service Two Vulnerabilities SECUNIA ADVISORY ID: SA17863 VERIFY ADVISORY: http://secunia.com/advisories/17863/ CRITICAL: Highly critical IMPACT: DoS, System access WHERE: >From remote SOFTWARE: Ipswitch Collaboration Suite (ICS) 2.x http://secunia.com/product/5167/ IMail Server 8.x http://secunia.com/product/3048/ DESCRIPTION: Two vulnerabilities have been reported in IMail Server, which can be exploited by malicious users to cause a DoS (Denial of Service) and to compromise a vulnerable system. 2) An error exists in the IMAP4D32 service when handling user supplied arguments passed to the IMAP LIST command. This can be exploited by a logon user to cause a memory dereferencing error, which crashes the IMAP service by supplying an argument of approximately 8000 bytes to the command. The vulnerabilities have been reported in IMail Server version 8.20. Other versions prior to 8.22 may also be affected. SOLUTION: Update to the fixed versions. IMail Server 8.20: Update to version 8.22. http://www.ipswitch.com/support/imail/releases/imail_professional/im822.asp Ipswitch Collaboration Suite 2.0: Update to version 2.02. http://www.ipswitch.com/support/ics/updates/ics202.asp PROVIDED AND/OR DISCOVERED BY: 1) Nico 2) Sebastian Apelt ORIGINAL ADVISORY: http://www.idefense.com/application/poi/display?id=346&type=vulnerabilities http://www.idefense.com/application/poi/display?id=347&type=vulnerabilities ---------------------------------------------------------------------- About: This Advisory was delivered by Secunia as a free service to help everybody keeping their systems up to date against the latest vulnerabilities.

BACKGROUND Ipswitch Collaboration Suite provides e-mail and real-time collaboration, calendar and contact list sharing, and protection from spam and viruses, all delivered in an easy to use suite. http://www.ipswitch.com/products/collaboration/index.asp II. All of the commands are handled by the same function which parses user-supplied input strings. The following debugger session shows a backtrace with user-supplied strings as values. With properly constructed input value, the strings would be interpreted as memory addresses that would be executed upon returning from the current function.

Ipswitch mail services are commonly configured to allow untrusted access. The use of a firewall or other mitigating strategy is highly recommended due to the nature of this vulnerability. The IMail SMTP server is installed by default. IV. V. WORKAROUND iDEFENSE is currently unaware of any effective workarounds for this issue. Access to the affected host should be filtered at the network boundary if global accessibility is not required. Restricting access to only trusted hosts and networks may reduce the likelihood of exploitation. VI.
