Introduction: Why a 20-Year-Old Bug Still Matters

1. Packet Crafting: The attacker would create a malicious packet containing a large amount of data, typically using a combination of SQL commands and shellcode.
2. Sending the Packet: The attacker would send the packet to the MySQL server, which would process the input data.
3. Buffer Overflow: The mysql_real_escape_string() function would attempt to escape the special characters in the input data, but due to the large size of the data, it would overflow the buffer.
4. Arbitrary Code Execution: The attacker could then execute arbitrary code on the server, potentially leading to a system compromise.

// Inside mysql_real_connect() char server_version[256]; // Fixed-size buffer on stack // ... packet = get_server_handshake(MySQL socket); // Extract version string from packet, no length check strcpy(server_version, packet->version); // BOOM – overflow if version > 255 bytes MySQL 5

An attacker would set up a rogue MySQL server. When a vulnerable client connects, the server replies with a handshake packet containing: Packet Crafting : The attacker would create a
