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
icewind1991 SMB before 1.0.3 allows remote authenticated users to execute arbitrary SMB commands via shell metacharacters in the user argument in the (1) listShares function in Server.php or the (2) connect or (3) read function in Share.php.

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
How this class of weakness works · CWE-78

User input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

Recommended fix High confidence

SMB library version 1.0.3 or later (or OwnCloud 8.1.2+ if using OwnCloud)

  1. 1. Identify the current version of the icewind1991/SMB library in your project (check composer.json or composer.lock)
  2. 2. If using Composer, update the version requirement in composer.json to require "icewind1991/smb": ">=1.0.3"
  3. 3. Run "composer update icewind1991/smb" to install the fixed version
  4. 4. Verify the installed version is 1.0.3 or later using "composer show icewind1991/smb"
  5. 5. Test that the application functionality (listShares, connect, read) continues to work correctly
  6. 6. If using OwnCloud, also ensure OwnCloud is updated to version 8.1.2 or later which contains the patched SMB library
