CVSS 2.0 Base Metrics
Reference Base Vector Base Score
CVE-2011-3389 (AV:N/AC:M/Au:N/C:P/I:N/A:N) 4.3
Information on CVSS is documented in HP Customer Notice: HPSN-2008-002
RESOLUTION
CERT VU#864643 documents workarounds.
Prioritize RC4 Ciphers over CBC Ciphers
The vulnerability can be worked around by prioritizing RC4 ciphers over CBC
ciphers.
By default SMH already does prioritize the RC4 ciphers over CBC ciphers. The
default configuration is:
'ALL:!ADH:!EXPORT56:!EXPORT40:RC4+RSA:+HIGH:+MEDIUM:-SSLv2:+EXP:-LOW:+eNULL'
The list of available ciphers in SMH can be further restricted. The following
command specifies only one cipher:
smhconfig -Z 'RC4-SHAâ
After issuing the command, the SMH service must be restarted to make the
change effective. The change should be tested with the browser.
Update the Browser
Certain browsers have implemented a protocol change to work around the
vulnerability. CERT VU#864643 lists some of those browsers.
