cmctl is the Connection Control Manager, part of the Oracle 8i installation. A vulnerability exists that can allow elevation of privileges.
|
|
|
|
The problem occurs in the way cmctl handles the user-supplied command line arguments. The string representing argv[1] (the first user-supplied commandline argument) is copied into a buffer of predefined length without being checked to ensure that its length does not exceed the size of the destination buffer. As a result, the excessive data that is written to the buffer will write past its boundaries and overwrite other values on the stack (such as the return address).
|
|
|
|
This can lead to the user executing supplied shellcode with the effective privileges of cmctl, egid dba and euid oracle.
