• → Monitor POST requests to /index.php?/manage/channel/addchannel for SQL injection payloads in the 'channel_name' or 'platform' parameters, specifically error-based patterns using CONCAT/FLOOR/RAND or time-based blind patterns using SLEEP(). ↗
• → Look for the hex-encoded marker strings 0x7171706b71 and 0x71786a7671 in POST body data, which are used as delimiters in the error-based SQLi payload to extract data from INFORMATION_SCHEMA.PLUGINS. ↗
• → Detect time-based blind SQL injection attempts via SLEEP(5) injected into the channel_name parameter on the addchannel endpoint; responses with anomalous latency (~5s) indicate exploitation. ↗
• → The vulnerable code resides in /application/controllers/manage/channel.php lines 75-95; the channel_name and platform parameters are passed to SQL queries without sanitization or filtering. ↗

• · The PoC targets a localhost instance; in real deployments the base URL will differ. Detection rules should match on the URI path /index.php?/manage/channel/addchannel regardless of host. ↗
• · Exploitation requires access to the /manage/ endpoint; assess whether authentication is enforced before the addchannel controller is reached, as this affects the attack surface. ↗
