What an attacker can do
An unauthenticated attacker can smuggle a malicious serialized PHP object into the cache, and when it is deserialized, a gadget chain writes an arbitrary PHP file inside the modules/ps_facetedsearch/ directory, which is then used as a webshell to run commands on the server. Vendor/CNA’s CVSS 3.1 assessment (base score 10.0/10) rates confidentiality, integrity and availability impact as high.
