- -- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of IBM Tivoli Storage Manager Express for
Microsoft SQL. Authentication is not required to exploit this
vulnerability.
The specific flaw resides in the Data Protection for SQL CAD service,
dsmcat.exe, which listens by default on a TCP port above 1024. The
process trusts a user-supplied size value, receiving the specified
amount of data into a static heap buffer. By sending a specially crafted
packet, an attacker can overflow that buffer leading to arbitrary code
execution in the context of the SYSTEM user.
- -- Vendor Response:
IBM has issued an update to correct this vulnerability. More
