Unknown · Concrete Cms · CVE-2022-21829
**Name of the Vulnerable Software and Affected Versions**
Concrete CMS versions 9.0.0 through 9.0.2
Concrete CMS versions 8.5.7 and below
**Description**
The issue allows an attacker to download zip files over HTTP and execute code from those zip files, potentially leading to a remote code execution (RCE). This is resolved by enforcing `concrete secure` instead of `concrete`, ensuring Concrete CMS only makes requests over HTTPS, even if a request comes in via HTTP.
**Recommendations**
For Concrete CMS versions 9.0.0 through 9.0.2, update to a version that enforces `concrete secure` instead of `concrete` to ensure requests are made over HTTPS.
For Concrete CMS versions 8.5.7 and below, update to a version that enforces `concrete secure` instead of `concrete` to ensure requests are made over HTTPS.
As a temporary workaround, consider restricting the ability to download zip files over HTTP until a patch is available.
