-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of IBM Tivoli Storage Manager Express.
Authentication is not required to exploit this vulnerability.
The specific flaw exists in the dsmcad.exe process bound by default on
TCP port 1581. During HTTP header parsing, a host parameter of
sufficient length will trigger an overflow through a call to
vswprintf(). The call overflows into imported function pointers which
are later called. Exploitation of this issue can result in arbitrary
code execution.
