CVE-2015-9357 is a cross-site scripting (XSS) vulnerability in the Akismet plugin for WordPress, affecting versions prior to 3.1.5. The vulnerability allows attackers to inject arbitrary web scripts or HTML via unspecified vectors, which are then executed in the context of users visiting affected WordPress sites.

This repository is a small standalone Python proof-of-concept exploit for CVE-2015-9357, containing one executable script and a README. The main file, CVE-2015-9357-poc.py, automates a stored XSS-to-admin-takeover chain against vulnerable WordPress input handling that performs smiley/emoticon parsing. The script starts a local HTTP listener, crafts an HTML/JavaScript payload that breaks out of an attribute context, and submits that payload to an operator-specified vulnerable endpoint and field. When an authenticated administrator later views the stored content, the injected JavaScript runs in the admin's browser, requests /wp-admin/user-new.php, extracts the create-user nonce, sends that nonce back to the attacker listener, and then submits a forged POST to create a new administrator account with hardcoded credentials: pwned / Password123! / pwned@evil.com. After receiving the nonce, the Python script waits briefly and then attempts to authenticate to /wp-login.php to confirm successful account creation. The exploit is operational rather than a mere detection script because it performs end-to-end exploitation and account creation, but it uses a basic hardcoded payload and requires manual knowledge of the vulnerable submission endpoint and field. The README explains the attack chain, usage syntax, and the dependency on a target field that actually undergoes WordPress smiley conversion.
