CVE-2022-40238
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 · uneditedA Remote Code Injection vulnerability exists in CERT software prior to version 1.50.5. An authenticated attacker can inject arbitrary pickle object as part of a user's profile. This can lead to code execution on the server when the user's profile is accessed.
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 confidenceThis is a Python pickle deserialization vulnerability in CERT software. An authenticated attacker can embed a malicious pickle object within a user's profile data. When that profile is accessed by the application or other users, the pickle is deserialized, triggering arbitrary code execution on the server.

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 Cert Vince installation versionLocate the installed Cert Vince package and retrieve its version number (common methods: check package manager, look for version file in installation directory, or run 'pip show' or similar command if installed via pip)Affected if Version is lower than 1.50.5
-
Inspect user profile storage mechanismExamine how user profile data is stored in the Cert Vince system - look for serialization format in the database or profile storage filesAffected if Profile data is serialized using Python pickle format
-
Verify if profile deserialization occurs on accessReview application code or configuration to confirm that user profile data is deserialized when profiles are loaded or displayedAffected if The application automatically deserializes profile data on access, enabling the pickle payload to trigger
-
Check authentication configurationDetermine whether user authentication is enabled and whether regular users can modify their own profile dataAffected if Authenticated users can modify profile fields that get stored via pickle serialization
A system is affected if it runs Cert Vince version below 1.50.5 and stores user profile data using Python pickle serialization, which gets deserialized when profiles are accessed.
Generated from the published advisory. Verify against your own configuration.
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 · scoped1.50.5
Upgrade to CERT software version 1.50.5 or later. Additionally, replace pickle serialization with safer alternatives like JSON for user profile data to prevent deserialization vulnerabilities.
Vince version 1.50.5 or later
- 1. Back up the current Vince installation and database before upgrading.
- 2. Locate the Vince installation directory on the server.
- 3. Upgrade to version 1.50.5 or later using the appropriate package manager or installation method (e.g., pip install --upgrade vince, or pull the latest Docker image, or git fetch and checkout v1.50.5).
- 4. Restart the Vince services to load the updated code.
- 5. Verify the upgrade was successful by checking the version number.
- 6. Test that user profile functionality works correctly after the upgrade.
- 7. Ensure no unauthorized access or code execution attempts have occurred by reviewing server logs.
