Security Bulletin: Password Disclosure via instrumentation log in Tivoli Storage Manager (IBM Spectrum Protect) Client (CVE-2016-8916)
When using the "set password" Tivoli Storage Manger (IBM Spectrum Protect) client command, the full text of the command and included password is written to the instrumentation log file if instrumentation tracing is enabled. For 18.104.22.168 and higher, instrumentation tracing is enabled by default but can be disabled by using the ENABLEINSTRUMENTATION NO setting. Prior to 22.214.171.124, instrumentation tracing was enabled by using the INSTRUMENT:* testflag.
DESCRIPTION: IBM Tivoli Storage Manager stores password information in a log file that could be read by a local user when a set password command is issued.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118472 for the current score
CVSS Environmental Score*: Undefined

Workarounds and Mitigations
For versions lower than 220.127.116.11:
- Examine dsm.opt (Windows) and dsm.sys (UNIX and Linux) for the presence of the INSTRUMENT:* test flag and remove the setting.
- Scan the client machine's file systems for file names matching the pattern "dsminstr.report.*". Either delete all of these files or delete only those files containing the set password command.
For versions 18.104.22.168 and higher:
- Examine dsm.opt (Windows) and dsm.sys (UNIX and Linux) for the presence of the ENABLEINSTRUMENTATION setting. If it does not exist, add ENABLEINSTRUMENTATION NO to the file, then restart any currently running client processes and services. If the setting does exist, make sure it is set to NO. Also check if INSTRLOGNAME is set; and if it is set, note the specified file name.
- Scan the client machine's file systems for files named "dsminstr.log" and files whose names match whatever is specified by INSTRLOGNAME. Either delete all of these files or delete only those files containing the set password command.
