Environment:

How to determine if the installation is affected

If you are running any release other than Spectrum 10.2.3, you need to verify the release level and patch level of all your SpectroSERVERs and OneClick web servers, to ensure they are not at risk.

To determine your release of Spectrum:

  1. CA OneClick Console: Click on Help -> About
  2. Open the Spectrum Console Panel on the SpectroServer and click on Help -> About
  3. On SpectroSERVER: Go to the Spectrum install directory, open the .installrc file and find the "VERSION"
  • For Spectrum 10.0.0 or older: Your release of Spectrum has already reach "End of Service". You will need to upgrade to Spectrum 10.2.3.
  • For Spectrum 10.1.0 - 10.1.1: You will need to upgrade to at least Spectrum 10.1.2 in order to patch your systems.
  • For Spectrum 10.2.0: You will need to upgrade to at least Spectrum 10.2.1 in order to patch your systems.
  • For Spectrum 10.1.2, Spectrum 10.2.1, or Spectrum 10.2.2: You need to check the patch level of each Spectrum server to determine if the server is at risk.

To check the patch level of each server:

  1. On the SpectroSERVER and OneClick Web Server: Go to the Spectrum Install directory.
  2. Locate the .history file. 
  3. Review the contents of the .history file, and look for an entry containing the following patch, that corresponds with your release of Spectrum:
    • Spectrum_10.01.02.PTF_10.1.239
    • Spectrum_10.02.01.PTF_10.2.193
    • Spectrum_10.02.02.PTF_10.2.227
  4. If you do not see an entry for the specified patch, that corresponds to your release of Spectrum, contact CA Spectrum Support and request a copy of the patch. It will be helpful to provide the contents of the .history file, so the CA Spectrum Support Engineer, can verify which patch you need.
