Preventing Shong from getting her CISSP
Summary: Cisco Talos published exploit.pl, a Perl script that XOR-encodes a Windows shellcode payload with a 121-byte key and appends a decoder stub plus an end marker. The script builds a 37-character prefix and a 0x1326-length postfix and pipes a 1,025-byte parameter string into a Cygwin-hosted binary at c:/cygwin/home/Administrator/abow5/abow5.exe.
Key Takeaway: The payload's decoded string is calc.exe, and the exploit is driven from a Cygwin path under an Administrator home directory, so a single script run can launch a process on a Windows host with no compiled binary of its own.
