    Is there any additional information regarding this vulnerability ?

    On March 1, 2016, the OpenSSL Software Foundation released a security advisory detailing seven vulnerabilities and a new attack, referred to as the Decrypting RSA with Obsolete and Weakened encryption (DROWN) attack. Of the seven vulnerabilities posted, three are related to the DROWN attack. DROWN exploits weaknesses in SSL version 2 (SSLv2) to enable an attacker to collect and decrypt TLS sessions. A successful attack requires the ability to collect traffic for a server that supports both TLS and SSLv2.

    Environments that have been configured to disable SSLv2 as well as export grade ciphers are not vulnerable to DROWN. Therefore if you have performed steps to mitigate both the TLS Logjam and POODLE attacks - you are not vulnerable

    DROWN Attack (CVE-2016-0800)


    According to R&D,

    Fortunately Portal 2.11 is not affected by this vulnerability. The Vulnerability is applicable for SSLV2 only and in Portal 2.11 comes with SSLv2 disabled.

    However the Portal 2.9 seems to be SSLv2 enabled. You can run the below command in the %BMC_PORTAL_KIT_HOME%/\webserver\tools\apache-openssl\bin folder command prompt on both portals to verify openssl s_client -connect <HOSTNAME>:443 -ssl2

    Whenever the command gives an error like 10148:error:1407F0E5:SSL routines:SSL2_WRITE:ssl handshake failure:.\ssl\s2_pkt.c:427:

    that mean the SSLv2 is not enabled.
    If you check the URL it is mentioned that if you have done POODLE vulnerability steps for Portal SSLv2 is not applicable for your Portal.

    POODLE vulnerability steps are at

    So would advise to perform these steps for Portal to be sure in case SSLv2 is enabled.
