CyberRota Analysis
AI-GeneratedThe InstaWP Connect plugin for WordPress is vulnerable to Remote Code Execution due to improper handling of its encrypted options file, which is exposed in a publicly accessible directory on Apache servers with directory indexing enabled. This flaw allows unauthenticated attackers to derive sensitive database access details and API signatures, posing a significant risk during the migration period. WordPress site administrators using this plugin, particularly those on Apache servers with directory listing enabled, should prioritize immediate remediation to mitigate potential exploitation.

Original NVD Description
The InstaWP Connect – 1-click WP Staging & Migration plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 0.1.3.6 via the (top-level script) function. This is due to the plugin stores its encrypted options file as options-{migrate_key}.txt in wp-content/instawpbackups/ without deploying an index.php or .htaccess to prevent directory listing, exposing the 40-character migrate_key on Apache servers with directory indexing enabled, which allows an attacker to derive the AES-256-CBC passphrase via SHA256(migrate_key), decrypt the options file to recover the api_signature. This makes it possible for unauthenticated attackers to get the database access details and api_signature. Exploitation requires the target WordPress site to be hosted on Apache with directory listing enabled (Options +Indexes) for the wp-content/instawpbackups/ directory, and time limited because it can only be exploited during the migration period.
