Module Overview

Name: Solaris KCMS + TTDB Arbitrary File Read
Module: auxiliary/admin/sunrpc/solaris_kcms_readfile
Source code: modules/auxiliary/admin/sunrpc/solaris_kcms_readfile.rb
Disclosure date: 2003-01-22
Last modification time: 2019-10-05 13:50:30 +0000
Supported architecture(s): -
Supported platform(s): -
Target service / protocol: -
Target network port(s): 111
List of CVEs: CVE-2003-0027

This module targets a directory traversal vulnerability in the kcms_server component from the Kodak Color Management System. By utilizing the ToolTalk Database Server\'s TT_ISBUILD procedure, an attacker can bypass existing directory traversal validation and read arbitrary files. Vulnerable systems include Solaris 2.5 - 9 SPARC and x86. Both kcms_server and rpc.ttdbserverd must be running on the target host.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
