CVE-2023-5815 | News & Blog Designer Pack – WordPress Blog Plugin <= 3.4.1 - Unauthenticated Remote Code Execution via Local File Inclusion

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.

Base score Version Severity Vector Exploitability Impact Score source
8.1 3.1 HIGH
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
