EMC AutoStart ftAgent Multiple Remote Code Execution Vulnerabilities (ESA-2012-020)
High Nessus Plugin ID 61491
SynopsisThe remote Windows host has an application that is affected by multiple remote code execution vulnerabilities.
DescriptionThe version of EMC AutoStart on the remote host reportedly contains multiple remote code execution vulnerabilities :
- The EMC AutoStart ftAgent, when processing messages with opcode 0x32 and subcode 0x04, opcode 0x32 and subcode 0x02, opcode 0x03 and subcode 0x04, opcode 0x55 and subcode 0x16, opcode 0x55 and subcode 0x01, opcode 0x41 and subcode 0x12, opcode 0x32 and subcode 0x3C, opcode 0x32 and subcode 0x2A, performs arithmetic on an unvalidated, user-supplied value used to determine the size of a new heap buffer. This allows a potential integer wrap to cause a heap-based buffer overflow.
(ZDI-12-116, ZDI-12-117, ZDI-12-118, ZDI-12-120, ZDI-12-121, ZDI-12-122, ZDI-12-123, ZDI-12-124, respectively)
- The EMC AutoStart ftAgent, when processing messages with opcode 0x41 and subcode 0x00, uses an uninitialized stack variable in calculating a memory pointer. Also, the function uses signed extension and signed comparison when checking the uninitialized stack variable, which allows arbitrary negative values to bypass the check. This could result in corruption of a controlled memory location, which can be leveraged to execute code under the context of a privileged user. (ZDI-12-119)
Failed attacks may result in a denial of service.
SolutionUpgrade to version 5.4.3 or later.
