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
BMC Control-M branches 9.0.20 and 9.0.21 upon user login load all Dynamic Link Libraries (DLL) from a directory that grants Write and Read permissions to all users. Leveraging it leads to loading of a potentially malicious libraries, which will execute with the application's privileges. Fix for 9.0.20 branch was released in version 9.0.20.238. Fix for 9.0.21 branch was released in version 9.0.21.201.

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 · high confidence

BMC Control-M versions 9.0.20 and 9.0.21 load Dynamic Link Libraries (DLLs) from a directory with world-writable permissions. An attacker with write access to this directory can place a malicious DLL that will be automatically loaded and executed with the application's privileges upon user login, achieving local privilege escalation.

MitigationApply the vendor patches: upgrade Control-M 9.0.20 to version 9.0.20.238 or 9.0.21 to version 9.0.21.201. As an interim mitigation, restrict file system permissions on the DLL loading directory to prevent unauthorized write access.

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 installed Control-M version
    Use the Control-M utilities or check version files in the Control-M installation directory (typically under /opt/controlm or C:\ControlM) to determine the exact version number
    Affected if The installed version is 9.0.20 (any patch below 238) or 9.0.21 (any patch below 201)
  2. Locate the Control-M DLL loading directory
    Examine Control-M configuration files or process behavior to identify directories from which the application loads dynamic libraries at runtime
    Affected if A DLL loading directory exists within the Control-M installation or runtime path
  3. Check directory permissions for world-writable access
    Use OS commands (such as 'ls -ld' on Unix or 'icacls' on Windows) to inspect the permissions on the identified DLL loading directory
    Affected if The directory shows world-writable or equivalent permissions (Everyone:Write, 777, or similar)
  4. Verify if unprivileged users can write to the DLL directory
    Attempt to create a test file in the identified directory using a non-admin account, or review ACLs to confirm write access for non-privileged users
    Affected if Non-administrative or unprivileged users have write permissions to the directory

You are affected if Control-M version is 9.0.20.x before 9.0.20.238 or 9.0.21.x before 9.0.21.201 AND a DLL loading directory used by Control-M has world-writable permissions that allow unprivileged users to place files.

Fixed in 9.0.20.2389.0.21.201
Interim mitigation

Apply the vendor patches: upgrade Control-M 9.0.20 to version 9.0.20.238 or 9.0.21 to version 9.0.21.201. As an interim mitigation, restrict file system permissions on the DLL loading directory to prevent unauthorized write access.

Recommended fix High confidence

9.0.20.238 or 9.0.21.201 (depending on current branch)

  1. Identify current Control-M version by checking the installed version in the Control-M environment or using the version check utility
  2. If running 9.0.20.x (where x < 238), plan upgrade to version 9.0.20.238
  3. If running 9.0.21.x (where x < 201), plan upgrade to version 9.0.21.201
  4. Review BMC Control-M upgrade documentation for the target version
  5. Execute upgrade in a test environment first to validate
  6. Apply upgrade to production environment following standard change management procedures
  7. Verify the new version is running post-upgrade
Caveat Standard upgrade considerations apply - review BMC release notes for any compatibility changes or required pre-upgrade steps
