  • →Exploit traffic uses HTTP POST method targeting the exact URI /baseOpLog.do with a fixed URI length of 13 bytes.
  • →The POST body contains the parameter 'opTime' with a value beginning with 'Begin=' or 'End=', followed by SQL comment byte sequences (0x27 = single-quote, 0x2f2a = /*, 0x2a2f = */) indicating SQL injection payload structure.
  • →The injection point is the opTime parameter, which accepts Begin= or End= prefixed values; the attack injects a single-quote followed by SQL block comment delimiters (/* */) to manipulate the query.
  • ·The Snort/Suricata rule targets both perimeter and internal deployment zones, indicating the vulnerable endpoint may be exposed externally or reachable from internal network segments.
  • ·The affected product is classified as IoT; standard web application firewall rules may not be deployed in front of ZKBioSecurity V5000 devices by default.
