Hello Assurent & Oracle,

According to Assurent, this is a remote overflow that creates a DoS condition. No mention of running arbitrary code.
Oracle's advisory says:
CVSS Severity Score: 10.0 (High) Attack Range (AV): Network Attack Complexity (AC): Low Authentication Level (Au): None Impact Type:Complete confidentiality, integrity and availability violation Vulnerability Type: Denial of Service CVSS Base Score Vector: (AV:N/AC:L/Au:N/C:C/I:C/A:C)
So it is a "Denial of Service" but results in a complete compromise of confidentiality, integrity and availability. A 10.0 score typically means remote, unauthenticated execution of attacker-controlled code. Which is correct?
Further, Oracle's advisory says this affects "Security vulnerability in WebLogic plug-ins for Apache, Sun and IIS Web servers", implying this affects multiple plug-ins, not just the one for Apache. The advisory also uses this wording further suggesting three separate plug-ins: "This vulnerability may impact the availability, confidentiality or integrity of WebLogic Server applications, which use the Apache, Sun or IIS web server configured with the WebLogic plug-in for Apache, Sun or IIS respectively."
Is it really one plug-in that works with all three? Or does this only affect an Apache plug-in?
