JVNDB-2014-000048

Vulnerability from jvndb - Published: 2014-06-06 04:48 - Updated:2016-12-27 02:49
Severity
N/A (UNKNOWN) - -
Summary
OpenSSL improper handling of Change Cipher Spec message
Details
OpenSSL improperly handles Change Cipher Spec message in the initial SSL/TLS handshake. OpenSSL contains a flaw in the implementation of the Change Cipher Spec protocol that allows a MITM (man-in-the-middle) attacker to force a server and a client to use easily guessable cryptgraphic key material during the initial SSL/TLS handshake (CWE-325). KIKUCHI Masashi of Lepidum Co. Ltd. reported this vulnerability to JPCERT/CC. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
