Impact
Akeneo PIM Community Edition versions before v5.0.119 and v6.0.53 allows remote authenticated users to execute arbitrary PHP code on the server by uploading a crafted image.
Patches
Akeneo PIM Community Edition after the versions aforementioned provides patched Apache HTTP server configuration file, for docker setup and in documentation sample, to fix this vulnerability.
Community Edition users must change their Apache HTTP server configuration accordingly to be protected.
The patch for Cloud Based Akeneo PIM Services customers has been applied since 30th October 2022.
