CVE-2022-29528
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 · uneditedAn issue was discovered in MISP before 2.4.158. PHAR deserialization can occur.
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 analysisThe application rebuilds objects from attacker-supplied serialized data, and the act of rebuilding can trigger dangerous code paths. In many runtimes this leads straight to remote code execution. The durable fix is to avoid deserializing untrusted input — or to use a strict, type-limited format with integrity checks.

MISP version 2.4.158
- Backup the existing MISP database and configuration files before proceeding with the upgrade.
- Ensure the server meets the prerequisites for MISP 2.4.158 including PHP version requirements.
- Download MISP version 2.4.158 from the official GitHub repository or use git to checkout the release tag: git checkout 2.4.158
- Replace the existing MISP installation files with the new version, preserving local configuration and customizations.
- Run any database migration scripts if included in the release (typically via CakePHP console or provided upgrade scripts).
- Verify the installation by logging into the MISP web interface and checking for any errors.
- Test that key functionality works correctly after the upgrade.
