Cloud, Physical, Virtual
Multiple security vulnerabilities exist in the IBM Java Runtime Environment
component of WebSphere Cast Iron in IBM JRE 6.0 SR15 (and earlier) and
IBM JRE 7.0 SR5 (and earlier)
There are multiple security vulnerabilities in the IBM Java Runtime
Environment used in WebSphere Cast Iron.
The DocumentHandler used by the java.beans.XMLDecoder implementation allows
the use of external entities by default. This facilitates a variety of
attacks via malicious XML data.
CVSS Base Score: 5.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90340 for the
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/L:Au/S:C/P:I/N:A/P)
javax.security.auth.Subject is serializable but does not validate
deserialized data properly. Malicious code could exploit this to construct
an invalid Subject instance with content that differs from the advertised
properties. In addition, if a server deserializes serialized data from
untrusted sources, an attacker could insert an invalid instance of Subject
class into a server Java process.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90349 for the
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/L:Au/N:C/N:I/P:A/N)
Timing differences based on validity of TLS messages can be exploited
to decrypt the entire session. The exploit is not trivial, requiring a
man-in-the-middle position and a long time (around 20 hours).
CVSS Base Score: 4
