Loading vulnerability…
CVE-2009-3699 is a stack-based buffer overflow in libcsa.a, the calendar daemon library used by rpc.cmsd, affecting IBM AIX 5.x through 5.3.10, AIX 6.x through 6.1.3, and VIOS 2.1 and earlier. A remote attacker can trigger the overflow by supplying an overly long XDR string as the first argument to procedure 21 of rpc.cmsd, resulting in arbitrary code execution.

This repository contains a single Metasploit module (modules/exploits/aix/rpc_cmsd_opcode21.rb) that exploits a buffer overflow vulnerability (CVE-2009-3699) in the rpc.cmsd (Calendar Manager Service Daemon) on IBM AIX 5.1. The exploit targets the SunRPC service (program number 100068, version 4) and abuses opcode 21 (rtable_create) by sending a specially crafted request with an overly long argument, resulting in a stack-based buffer overflow. The module supports brute-forcing the return address within a specified range for successful exploitation. If successful, the attacker gains arbitrary code execution on the target system, with payloads generated and managed by the Metasploit framework. The exploit is operational and can be used to gain shell access or run custom code on vulnerable AIX systems. The repository is structured as a typical Metasploit module, written in Ruby, and is intended for use within the Metasploit framework.
