CVE-2020-13575Public exploitNetwork attack vector

Service crash via unchecked FaultTo Address

Published Feb 10, 2021 · Updated Feb 13, 2025

NULL pointer dereference in the WS-Addressing plugin in Genivia gSOAP 2.8.107 allows remote attackers to crash a service via SOAP. In wsaapi.c, soap_wsa_fault_subcode_action passes FaultTo->Address to strcmp without checking whether an omitted Address element left the pointer null. A network-reachable HTTP service must use the WS-Addressing plugin and process a FaultTo element without Address; the resulting segmentation fault crashes that service without reported data exposure or modification.
