A code execution vulnerability exists in the WS-Addressing plugin functionality of Genivia gSOAP 2.8.107. A specially crafted SOAP request can lead to remote code execution. An attacker can send an HTTP request to trigger this vulnerability.

Weakness

The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
