Unspecified vulnerability in the OPMN component in Oracle Application Server 10.1.2.3 allows remote attackers to affect confidentiality integrity and availability via unknown vectors. NOTE: the previous information was obtained from the April 2009 CPU. Oracle has not commented on reliable researcher claims that this issue is a format string vulnerability that allows remote attackers to execute arbitrary code via format string specifiers in an HTTP POST URI which are not properly handled when logging to opmn/logs/opmn.log.
