CAPKI (Previously known as ETPKI) is a C language-based Software Development Kit (SDK) that provides CA Development Community with features required to implement Information Security services in its products. CAPKI is a wrapper on OpenSSL which is robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols.
NOTE: Siteminder r12.9 Access Gateway Server uses CAPKI 6.
Environment
PRODUCT: Symantec Siteminder
COMPONENT: Access Gateway Server
VERSION: r12.8.8.1 and Older
OPERATING SYSTEM: Windows and Linux
Cause
CAPKI (Previously known as ETPKI) is a wrapper on OpenSSL. CAPKI 5.2.x is built with OpenSSL 1.0.2.
The Siteminder Access Gateway Server ships with the following versions of CAPKI:
Siteminder Policy Server r12.8.8.1 is shipped with CAPKI 5.2.14.0
Siteminder r12.8.7 and r12.8.8 are compiled with older versions of CAPKI built on older versions of OpenSSL 1.0.2
KB427910 (archived) delivered CAPKI 5.2.16
KB409256 (archived) delivered CAPKI 5.2.17
CAPKI 5.2.17 and older are compiled with versions of OpenSSL 1.0.2 which have vulnerabilities (CVE's) published.
Resolution
Upgrade CAPKI to CAPKI 5.2.18 on the Siteminder Access Gateway using this KB.
CAPKI 5.2.18 has been compiled with OpenSSL 1.0.2zp.
This solution applies to the following Siteminder Access Gateway Server versions:
- r12.8.8.1 and older
LINUX
1) Download "etpki-install_5_2_18_linux.zip" from this KB.
2) Copy "etpki-install_5_2_18_linux.zip" to the Siteminder Access Gateway Server on Linux and decompress it.
3) Stop the Access Gateway Server
4) Change to the following directory:
/<Install_Dir>/CA/secure-proxy/agentframework/
5) Backup the '/CAPKI/' directory by renaming it '/CAPKI.BAK'
mv CAPKI CAPKI.BAK
6) Copy the '/etpki-install/' directory from "etpki-install_5_2_18_linux.zip" to /<Install_Dir>/CA/secure-proxy/agentframework/
7) Change to the following directory*:
/<Install_Dir>/CA/SharedComponents/
* This directory may not exist in your system
8) (If Exists) Backup the '/CAPKI/' directory by renaming it '/CAPKI.BAK'
mv CAPKI CAPKI.BAK
9) Modify the $CAPKIHOME variable in the environment variable script:
/<Install_Dir>/CA/secure-proxy/ca_sps_env.sh
CAPKIHOME=/<Install_Dir>/CA/SharedComponents/CAPKI
export CAPKIHOME
10) Run the updated Access Gateway Environment variable script.
cd /<Install_Dir>/CA/secure-proxy/
. ./ca_sps_env.sh
11) Change to the following directory:
/<Install_Dir>/CA/secure-proxy/agentframework/etpki-install/redist/
12) Ensure the user has execute permissions on the installation media (setup)
13) Run the following command:
./setup install caller=sps12
NOTE: This will create a new '/<Install_Dir>/CA/SharedComponents/CAPKI/CAPKI5/' directory
14) Start the Access Gateway Server
15) Validate Access Gateway Server functionality
16) Delete the following files:
/<Install_Dir>/CA/secure-proxy/agentframework/CAPKI.BAK
(If Exists) /<Install_Dir>/CA/SharedComponents/CAPKI.BAK
WINDOWS
1) Download "etpki-install_5_2_18_win64.zip" from this KB.
2) Copy "etpki-install_5_2_18_win64.zip" to the Access Gateway Server on Windows and decompress it.
3) Stop the Access Gateway Server
4) Change to the following directory:
<Drive>:\<Install_Dir>\CA\secure-proxy\agentframework\ETPKI\
5) Backup the '\CAPKI\' directory by renaming it '\CAPKI.BAK\'
ren CAPKI CAPKI.BAK
6) Copy the '/etpki-install/' directory from "etpki-install_5_2_18_win64.zip" to <Drive>:\<Install_Dir>\CA\secure-proxy\agentframework\ETPKI\
7) Change to the following directory*:
<Drive>:\<Install_Dir>\CA\SC\
* This directory may not exist in your system
8) (If Exists) Backup the '\CAPKI\' directory by renaming it '\CAPKI.BAK\'
ren CAPKI CAPKI.BAK
9) Open a command prompt using cmd.exe as an administrator (Run As Administrator)
10) Change to the following directory:
<Drive>:\<Install_Dir>\CA\secure-proxy\agentframework\ETPKI\\etpki-install\redist\
11) Run the following command:
setup.exe install caller=sps12
NOTE: This will create a new '<Drive>:\<Install_Dir>\CA\SC\CAPKI\CAPKI5\' directory
12) Start the Access Gateway Server
13) Validate Access Gateway Server functionality
14) Delete the following files:
<Drive>:\<Install_Dir>\CA\secure-proxy\agentframework\ETPKI\CAPKI.BAK
(If Exists) <Drive>:\<Install_Dir>\CA\SC\CAPKI.BAK
