The following three issues are subparts of CVE-2011-1184, above, and are already addressed by the fix for that CVE:

CVE Label CVSS Base Score Vector
CVE-2011-5062 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)
CVE-2011-5063 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N)
CVE-2011-5064 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N)

These issues were discovered in a variety of ways, and all are assumed to be known publicly.

The Juniper SIRT is not aware of any specific malicious exploitation of these vulnerabilities against Juniper Networks NSM products.

No other Juniper Networks products or platforms are affected by this issue.
Solution:


All of the issues in this bulletin were resolved by a major upgrade of the Apache Tomcat web server in the NSM product.

NSM version 2011.4 (released in January 2012) and all subsequent releases contain the fixes for these issues.

KB16765 - "In which releases are vulnerabilities fixed?" describes which releases are fixed for vulnerabilities per Juniper Networks' "End of Engineering" and "End of Life" support policies.

Workaround:
It is always prudent to limit physical and network-based access to the NSM device. Due to the number and variety of issues included in this bulletin, it is impractical to provide a comprehensive workaround which would mitigate all of these issues.

Customers are strongly encouraged to upgrade to a release listed above.
Implementation:


How to obtain fixed software:

NSM Maintenance Releases are available at http://support.juniper.net from the "Download Software" links. If a Maintenance Release is not adequate and access to NSM patches is needed, open a customer support case. A JTAC engineer will review your request and respond, ensuring that you will be provided with the most appropriate Patch Release for your specific situation.
CVSS Score:
7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
Severity Level:
High
Severity Assessment:
(Note: This score is based on the highest-scoring individual issue in the set, see above.)

Information for how Juniper Networks uses CVSS can be found at KB 16446 "Common Vulnerability Scoring System (CVSS) and Juniper's Security Advisories."
