prestashop/ps_facetedsearch
source listedECOSYSTEM: introduced 3.0.0; fixed 4.0.4
### Impact A PHP Object Injection vulnerability affects the PrestaShop module `ps_facetedsearch`. The module rebuilds the selected search filters from the request URL. The value of a slider filter (**price** or **weight**) is taken from the URL without sufficient validation, then stored in an internal filter-block cache where it is serialized and later read back with a raw native `unserialize()`. By crafting that value, an attacker can smuggle a malicious serialized PHP object into the cache. When it is deserialized, a gadget chain writes an arbitrary PHP file inside the module directory, which is then used as a webshell to run commands on the server. ### Who is impacted Any shop using a vulnerable version of `ps_facetedsearch` that displays a filter template containing a slider filter (price or weight). Exploitation is remote and **unauthenticated**, a single crafted front-office request is enough, and leads to remote code execution and full compromise of the shop and its server. **Affected versions:** `3.0.0` through `4.0.3` (all versions since 3.0.0, including the latest release). ### Patches Upgrade the `ps_facetedsearch` module to the patched version.
