CVE-2025-36081
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 · uneditedIBM Concert Software 1.0.0 through 2.0.0 could allow a user to modify system logs due to improper neutralization of log input.
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 confidenceIBM Concert Software versions 1.0.0 through 2.0.0 contains a log injection vulnerability where improper neutralization of special elements in log input allows authenticated users to modify system logs. This could enable log poisoning or manipulation of audit trails.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed IBM Concert versionRun 'ibmconcert --version' or check the product's about/version information panel in the GUI or APIAffected if The version is 1.0.0 through 2.0.0 (or any version < 2.1.0)
-
Confirm authentication is enabledCheck the user authentication settings in the IBM Concert admin console or configuration filesAffected if User authentication is required to exploit this flaw, so the vulnerability applies only when authentication is active
-
Verify logging functionality is in useLocate and inspect the log configuration (typically in concert.conf or similar config file) and confirm log paths are configuredAffected if Log injection requires that logging to file, syslog, or another writable log destination is enabled
-
Review log files for injection indicatorsExamine recent log entries for unexpected formatting, duplicate timestamps, or suspicious content that could indicate injection attemptsAffected if Log files contain entries with unusual formatting, escape sequences, or forged entries that suggest the vulnerability was exploited
A user is affected if IBM Concert version is 1.0.0 or higher but below 2.1.0, authentication is enabled, and logging to a file or syslog is active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.1.0
Implement proper input validation and sanitization for all data written to logs, escaping or filtering special characters that could affect log formatting or allow injection of false entries.
IBM Concert version 2.1.0 or later
- 1. Identify the current installed version of IBM Concert (e.g., check via product UI, CLI, or configuration files)
- 2. Review IBM Concert 2.1.0 release notes for upgrade considerations and any migration requirements
- 3. Create a full backup of the IBM Concert configuration, databases, and any custom settings
- 4. Follow IBM's official upgrade documentation to update from the current version to version 2.1.0 or later
- 5. After upgrade, verify that the log injection vulnerability is resolved by testing log functionality
- 6. Confirm normal operation of all Concert features post-upgrade
