SA12 : OpenSSL Vulnerability
1029
03 March 2020

CLOSED
HIGH
SUMMARY
Some Blue Coat Products use versions of OpenSSL that are vulnerable to an attack based on malformed client certificates. The attacks can be aimed at any service on the appliance that is terminating (acting as a host for) an SSL connection. The vulnerabilities are such that disabling client certificates does not prevent the attack.
ISSUES
A successful attack will result in a restart of CA/SA and SG appliances, which can lead to a denial of service situation.
MITIGATION
Restricting access to the secure management console port to trusted IP addresses may reduce exposure.
