|CVSS SCORE||10, (AV:N/AC:L/Au:N/C:C/I:C/A:C)|
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of BMC Perform Agent. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the service daemon which listens by default on TCP port 6768. When processing the BGS_MULTIPLE_READS commands a user-supplied length value is trusted and utilized in reading arbitrary data into a stack buffer. By providing large enough values a remote attacker can abuse this to execute remote code under the context of the SYSTEM user.

Potential vulnerability in network accessible binaries Service Daemon and Manager Daemon
BMC Software has identified a potential security exposure in Perform binaries Service Daemon and Manager Daemon, which listen on a network port. (The default port is 6768.) This problem affects all supported versions of these products.
This is a remotely exploitable memory corruption that can result in the remote execution of arbitrary code such as the Perform Installation Owner account on UNIX, or the SYSTEM account on Windows.
You can correct this issue by downloading and applying the appropriate patch for your operating system and version of these products.
