2. Update mit erweiterten Hilfen zu Notfallmaßnahmen: Apache Log4j CVE-2021-44228 vulnerability in Bezug auf Spectrum Protect

2nd update Dec. 15, 2021, 11 a.m.

Probably only backup/archive client installations with configured WebClient and Spectrum Protect for Virtual Environments with active web server (vSphere plugin) are vulnerable.

The reports about Log4j do not stop. A colleague discovered the following additional CVE 2021-45046 this morning:
https://www.lunasec.io/docs/blog/log4j-zero-day-update-on-cve-2021-45046/

Laut Meldungen aus ADSM.org und unseren eigenen Recherchen sind wahrscheinlich nur Backup/Archive Client Installationen mit konfiguriertem WebClient und Spectrum Protect for Virtual Environments mit aktivem Web Server (vSphere Plugin) angreifbar.

According to reports from ADSM.org and our own research, probably only Backup/Archive Client installations with configured WebClient and Spectrum Protect for Virtual Environments with active Web Server (vSphere plugin) are vulnerable.

 

Therefore, the simplest workaround is to temporarily disable the WebClients and stop the TDP4VE Web Server.

Disable Web Client under Windows

Disable Web Client under Unix/Linux

Um den Spectrum Protect for Virtual Environments Web Server zu beenden

  • Net stop “IBM Spectrum Protect for Virtual Environments Web Server”
  • Oder Net stop IBMVEWebServer

Der Dienst sollte anschliessend auf manuell gestellt werden.

To stop the Spectrum Protect for Virtual Environments Web Server

Add the last line (-Dlog4j2.formatMsgNoLookups=true) in C:\IBM\SpectrumProtect\webserver\usr\servers\veProfile\jvm.options, so that it looks like this:

-Dlog4j2.formatMsgNoLookups=true

then restart "IBMWebserver".

This workaround works for Spectrum Protect clients of version 8.1.11 to 8.1.13!

However, currently only an update to Log4j version 2.16.0 is a permanent solution. For this we have to wait for a fixed Spectrum Protect Client version from IBM.
