Vulnerability Details

These vulnerabilities allow a remote attacker to execute arbitrary code on vulnerable installations of Computer Associates' BrightStor Hierarchical Storage Manager. Authentication is not required to exploit these vulnerabilities.

The specific flaws exist in the CsAgent service that listens by default on TCP port 2000. An opcode parsing switch statement multiplexes data funneling across various vulnerable routines. A user-supplied DWORD size value is assumed by the vulnerable agent to contain the correct length of the subsequent data and is passed directly to memory allocation routines. At least 26 out of the available 68 opcodes are vulnerable to various overflows that allow for remote code execution due to insecure data copy operations, including: 0x01, 0x06 - 0x09, 0x0d, 0x10, 0x16 - 0x18, 0x1E, 0x1F, 0x21, 0x22, 0x26, 0x27, 0x29, 0x32, 0x36, 0x38, 0x3A - 0x3C, 0x3E and 0x40.
