Technical details

A vulnerability exists in the `to_zval_map()` function within `ext/soap/php_encoding.c` of the PHP SOAP extension. When a SOAP server is configured with a typemap, the decoder incorrectly validates the `xmlKey` variable instead of `xmlValue` when processing the `<value>` branch of an `apache:Map` node. If a request contains an `apache:Map` node with a missing `<value>` element, the subsequent call to `master_to_zval_int()` attempts to access properties on a NULL pointer. This results in a segmentation fault and process crash. The issue is exploitable by a remote, unauthenticated attacker and has been patched in PHP versions 8.2.31, 8.3.31, 8.4.21, and 8.5.6.
