Arbitrary Code Execution via Type Confusion in PHP SoapClient

CVE-2015-6836 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

The SoapClient __call method in ext/soap/soap.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 does not properly manage headers, which allows remote attackers to execute arbitrary code via crafted serialized data that triggers a "type confusion" in the serialize_function_call function.
