Blog Designer Pack - Remote Code Execution (CVE-2023-5815)

CVE-2023-5815

The News & Blog Designer Pack – WordPress Blog Plugin — (Blog Post Grid, Blog Post Slider, Blog Post Carousel, Blog Post Ticker, Blog Post Masonry) plugin for WordPress is vulnerable to Remote Code Execution via Local File Inclusion in all versions up to, and including, 3.4.1 via the bdp_get_more_post function hooked via a nopriv AJAX. This is due to function utilizing an unsafe extract() method to extract values from the POST variable and passing that input to the include() function. This makes it possible for unauthenticated attackers to include arbitrary PHP files and achieve remote code execution. On vulnerable Docker configurations it may be possible for an attacker to create a PHP file and then subsequently include it to achieve RCE.

Potential Impact

Severity is HIGH (CVSS 8.1). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as Very High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.

What to do about this

Patch immediately Serious, and reachable without meaningful privilege.

Fix it

Update Blog Designer Pack to the latest available version.

Where the vendor has not published a fix yet, disable the plugin until they do.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.

Am I affected by this vulnerability?

You are affected if your site runs Blog Designer Pack. No account is needed to exploit this, so a public site is reachable by anyone.

How do I fix it?

Update Blog Designer Pack to the latest available version. Where the vendor has not yet published a fix, remove or disable the plugin until they do. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

What can an attacker actually do?

This is a Remote Code Execution flaw. An attacker who exploits it can run their own code on the server, which is total control of the site.
