Alert Id 20015
Alert Type Active Scan Rule
Status beta
Risk High
CWE 119
WASC 20

Summary

The TLS implementation in OpenSSL 1.0.1 before 1.0.1g does not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, potentially disclosing sensitive information.

Solution

Update to OpenSSL 1.0.1g or later. Re-issue HTTPS certificates. Change asymmetric private keys and shared secret keys, since these may have been compromised, with no evidence of compromise in the server log files.
