Error description

  • An unauthorized access vulnerability in TSM for Space Management
    (HSM) enables remote attackers to read, modify or even delete
    files in dmapi enabled file systems mounted on systems where HSM
    is installed. The files can be read or modified without changing
    the atime, ctime or mtime file attributes.
    .
    All HSM platforms are affected:
    AIX with GPFS or JFS2, Linux, Solaris Sparc and HP-UX.
    .
    The following HSM versions are affected:
    6.3, 6.2, 6.1, 5.5 and 5.4.
    .
    The affected binary is the dsmrootd on AIX located in
    /usr/tivoli/tsm/client/hsm/bin or in
    /opt/tivoli/tsm/client/hsm/bin in case of Linux, Solaris or
    HP-UX.
    .
    IBM's assessment of the base Common Vulnerability Scoring System
    (CVSS) score for this vulnerability is 6.4.
    

Local fix

  • When GPFS is spacemanaged the dsmrootd binary must be replaced
    by a script which runs as a background process upon start.
    When JFS2 or VxFS is spacemanaged the dsmrootd binary must be
    deleted. A script which replaces the dsmrootd is not required in
    the latter case.

Problem conclusion

  • The problem has been fixed so that it no longer occurs. The
    dsmrootd has been removed. HSM command execution by non-root
    users has been disabled. HSM 6.4.0 is not affected. The
    dsmrootd will be removed later with 6.4.1.
