Vulnerability Description
This Security Bulletin addresses weak cipher usage between NSP and NTBA and
Cross Site Scripting issues in NSM. The cipher issue is addressed by updating
third-party libraries, and the Cross Site Scripting issues were in McAfee's
code base.
Weak Cipher Usage in NSP and NTBA Communication
Communication from NSP Sensor M-series and VM-series to NTBA now uses
TLS1.2-RSA-AES128_GCM-SHA256. When updating NTBA to 9.1 Update 6, it is
recommended to also upgrade all co-deployed NSP sensors (M, NS, or VM series)
to maintain encrypted communication seamlessly.
1. CVE-2013-4559
lighttpd before 1.4.33 does not check the return value of the (1) setuid,
(2) setgid, or (3) setgroups functions, which might cause lighttpd to run
as root if it is restarted and allows remote attackers to gain privileges,
as demonstrated by multiple calls to the clone function that cause setuid
to fail when the user process limit is reached.
https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2013-4559
2. CVE-2015-3200
mod_auth in lighttpd before 1.4.36 allows remote attackers to inject
arbitrary log entries via a basic HTTP authentication string without a
colon character, as demonstrated by a string containing a NULL and new line
character.
https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2015-3200
3. CVE-2016-2183
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec
protocols and other protocols and products, have a birthday bound of
approximately four billion blocks, which makes it easier for remote
attackers to obtain cleartext data via a birthday attack against a
long-duration encrypted session, as demonstrated by an HTTPS session using
Triple DES in CBC mode, also known as a "Sweet32" attack.
https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2016-2183
Cross Site Scripting in NSM
1. CVE-2020-7256
Cross Site Scripting (XSS) vulnerability in McAfee Network Security Manager
(NSM) prior to 9.1 Update 6 allows an authenticated administrator to embed
an XSS in the administrator interface via a specially crafted custom rule
containing HTML.
https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2020-7256
https://nvd.nist.gov/vuln/detail/CVE-2020-7256
2. CVE-2020-7258
Cross Site Scripting (XSS) vulnerability in McAfee Network Security Manager
(NSM) prior to 9.1 Update 6 allows an authenticated administrator to embed
an XSS in the administrator interface via a specially crafted custom rule
containing HTML.
https://cve.mitre.org/cgi-bin/cvename.cginame=CVE-2020-7258
https://nvd.nist.gov/vuln/detail/CVE-2020-7258

What is CVSS
CVSS, or Common Vulnerability Scoring System, is the result of the National
Infrastructure Advisory Council's effort to standardize a system of assessing
the criticality of a vulnerability. This system offers an unbiased criticality
score between 0 and 10 that customers can use to judge how critical a
vulnerability is and plan accordingly. For more information, visit the CVSS
website at: http://www.first.org/cvss/ .
When calculating CVSS scores, McAfee has adopted a philosophy that fosters
consistency and repeatability. Our guiding principle for CVSS scoring is to
score the exploit under consideration by itself. We consider only the immediate
and direct impact of the exploit under consideration. We do not factor into a
score any potential follow-on exploits that might be made possible by the
successful exploitation of the issue being scored.
