This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of HP 3com/H3C Intelligent Management Center. Authentication is not required to exploit this vulnerability.
The flaw exists within the tftpserver.exe component which listens by default on UDP port 69. When handling the transfer mode field this value is passed through toupper before being stored in a local buffer for string comparison. The process does not properly verify the destination buffer on the stack is sufficient size to handle the newly created string. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the SYSTEM user.
