Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
IBM Concert 1.0.0 through 2.1.0 could allow a local user with specific knowledge about the system's architecture to escalate their privileges due to incorrect file permissions for critical resources.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

IBM Concert versions 1.0.0 through 2.1.0 contains incorrect file permissions on critical system resources that allow a local authenticated user with specific architectural knowledge to escalate privileges to higher permission levels, likely root or administrator.

MitigationAudit and correct file permissions on critical resources following the principle of least privilege; ensure sensitive configuration files, binaries, and directories are owned by appropriate privileged users and not writable by low-privilege local accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify IBM Concert version
    Run 'ibmconcert version' or check the installed package version using your system's package manager (e.g., rpm -q ibm-concert, dpkg -l ibm-concert, or brew list ibm-concert)
    Affected if The installed version is 1.0.0 through 2.1.0 (anything below 2.2.0)
  2. Locate IBM Concert binaries and scripts
    Find the installation directory - common locations include /opt/ibm/concert, /usr/local/ibmconcert, or the directory returned by 'which ibmconcert'. Use 'find /opt -name ibmconcert 2>/dev/null' or 'find /usr -name ibmconcert 2>/dev/null' if the binary location is unknown
    Affected if The installation directory exists and contains binaries/scripts in version range 1.0.0 to 2.1.0
  3. Inspect file permissions on binaries and executables
    Run 'ls -la' on the IBM Concert installation directory and subdirectories. Check each binary, script, and executable file for permissions. Specifically look for files that are writable by group or other (permissions containing 'w' in g or o)
    Affected if Any critical binary or executable is writable by non-privileged users (permissions show 'w' for group or other, e.g., -rw-rw-r-- or -rwxrwxrwx)
  4. Inspect file permissions on configuration files
    Run 'ls -la' on configuration directories (commonly config/, etc/, or conf/ within the IBM Concert installation). Check for .conf, .yaml, .json, .xml, or .properties files that may contain sensitive data
    Affected if Configuration files are writable by non-privileged users or owned by a low-privilege account
  5. Check ownership of critical resources
    Run 'ls -la' on the main IBM Concert directory and verify that sensitive files (binaries, config, data directories) are owned by root or a privileged service account, not by a standard user account
    Affected if Critical resources are owned by unprivileged users or user groups that include local authenticated non-admin accounts

A system is affected if IBM Concert version is below 2.2.0 AND critical files/directories are writable by or accessible to non-privileged local users.

Upgrade available Upgrade to 2.2.0 or later
Fixed in 2.2.0
Interim mitigation

Audit and correct file permissions on critical resources following the principle of least privilege; ensure sensitive configuration files, binaries, and directories are owned by appropriate privileged users and not writable by low-privilege local accounts.

Recommended fix High confidence

2.2.0

  1. 1. Backup the current IBM Concert installation and any critical data.
  2. 2. Download IBM Concert version 2.2.0 or later from the official IBM Fix Central or product download portal.
  3. 3. Install the upgraded version following IBM's standard upgrade procedures for your deployment model.
  4. 4. After upgrade, verify that file permissions on critical resources (binaries, configuration files, libraries) are correctly set according to IBM's security guidelines.
  5. 5. Test that IBM Concert functions normally and that the privilege escalation vulnerability is no longer present.
