Think of it as a data bunker.ĭespite the schematic nature of the above diagram, the architecture is quite complex. Vault Partitions are specific areas where stored backups are immutable. Between the peculiarities of Data Domains are the obvious RAID 6 storage, the possibility of backup encryption, data deduplication, compression, and a less obvious Vault Storage. Data Domains are DELL hardware (DELL EMC Data Domain) acting as Network Attached Storage ( NAS) devices.Those instances are abstraction layers for the physical devices where the backups will be stored (Data Domains). one for the DBs, one for Windows Servers, one for AIX, etc.). TSM Server keeps instances of different backups (e.g.

Agents installed on servers will gather and push backups to a remote TSM Server.Tivoli’s Architecture could be summarized as follows: TSMManager Viewer – Reverse Engineering & Binary Patching.One of the flags was to breach, if possible, the server responsible for backup collection and storage.Īll the scripts, patched clients and documentation can be found on my GitHub repository. I cannot verify if this vulnerability is also affecting the newer IBM Spectrum Protect, so, good luck with that.ĭuring a recent red-team engagement I had the opportunity to test the backup infrastructure of one of my clients.IBM Tivoli Storage Manager has reached its end of life support and will not be patched.Unfortunately, after I had one of the rudest encounters with an Hackerone’s triager, these are the takeaways: A Stack Based Buffer Overflow affecting IBM Tivoli Storage Manager – ITSM Administrator Client Command Line Administrative Interface (dsmadmc.exe) Version 5, Release 2, Level 0.1.

CVE-2020-28054: An Authorization Bypass vulnerability affecting JamoDat – TSMManager Collector v.
