|Alert Impact||Not Applicable|
|Technical Details||False positive|
|Technical Details Explanation||Severity: High|
A cross-protocol attack was discovered that could lead to decryption of TLS
sessions by using a server supporting SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle. Note that traffic between clients and
non-vulnerable servers can be decrypted provided another server supporting
SSLv2 and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or
POP) shares the RSA keys of the non-vulnerable server. This vulnerability is
known as DROWN (CVE-2016-0800).
Recovering one session key requires the attacker to perform approximately 2^50
computation, as well as thousands of connections to the affected server. A more
efficient variant of the DROWN attack exists against unpatched OpenSSL servers
using versions that predate 1.0.2a, 1.0.1m, 1.0.0r and 0.9.8zf released on
19/Mar/2015 (see CVE-2016-0703).
Users can avoid this issue by disabling the SSLv2 protocol in all their SSL/TLS
servers, if they've not done so already. Disabling all SSLv2 ciphers is also
sufficient, provided the patches for CVE-2015-3197 (fixed in OpenSSL 1.0.1r and
1.0.2f) have been deployed. Servers that have not disabled the SSLv2 protocol,
and are not patched for CVE-2015-3197 are vulnerable to DROWN even if all SSLv2
ciphers are nominally disabled, because malicious clients can force the use of
SSLv2 with EXPORT ciphers.
|Resolution||RSA Authentication Manager 3.0.4/7.1.4, 8.1 and 8.1 SP1 P11 is not impacted as SSLv2 is not utilized.|
