Symantec Endpoint Protection (SEP) 12.1.6 addresses vulnerabilities that were
found in prior releases. These include an authorized but less-privileged
administrator able to attempt a blind SQL injection in the SEP Manager (SEPM)
console through PHP prepared statements; a local Denial of Service (DoS) due
to the ability to create a deadlock in system functionality preventing
complete system shutdown and a local elevation of privilege potential through
a dll pre-loading weakness. These issues could result in potential access to
unauthorized data, inability to shut down or restart a system without doing a
hard power cycle or an authorized but non-privileged user possibly being able
to elevate their access to SYSTEM on a local client system.

Symantec Endpoint 12.1.5 and prior All Migrate to SEP 12.1.6
Symantec was notified of security issues that have been addressed with the
release of Symantec Endpoint Protection 12.1.6.
Symantec Endpoint Protection Manager is susceptible to a blind, time-based SQL
injection in some interface scripts used to manage the console. The management
console does not provide sufficient validation/sanitation of submitted input.
This could enable an authorized but less-privileged user to potentially run an
unauthorized arbitrary SQL query against the backend database. This would
include Limited Administrators as implemented in Symantec Endpoint Protection
Manager. This could possibly allow unauthorized access to data or unauthorized
manipulation of data.
SEP is susceptible to a local denial of service due to a deadlock condition in
sysplant.sys. A local user can create a local denial of service by running a
specifically formatted call resulting in the windows system unable to fully
shutdown. Resolution requires a hard power cycle to shut down and restart the
SEP is affected by potential dll loading issues resulting from improper path
restrictions in some file directories not properly restrict the loading of
external libraries. An authorized malicious local user with access to a system
could potentially insert a specifically-crafted file in one of the susceptible
directory. Such an attack would then need to entice an authorized user to load
a specifically formatted file from an alternate file location or network
share. Successful exploitation could allow unauthorized arbitrary code to be
executed with system permissions.
Symantec product engineers verified these issues. SEPM 12.1 RU6 contains
updates that address these findings.
Symantec is not aware of exploitation of or adverse customer impact from this
Symantec Endpoint Protection Manager 12.1 RU6 is available from Symantec File
Symantec strongly recommends as part of normal best practices:
Restrict access to administration or management systems to privileged users.
Restrict remote access, if required, to trusted/authorized systems only.
Run under the principle of least privilege where possible to limit the impact
of exploit by threats.
Keep all operating systems and applications updated with the latest vendor
Follow a multi-layered approach to security. Run both firewall and
anti-malware applications, at a minimum, to provide multiple points of
detection and protection to both inbound and outbound threats.
Deploy network and host-based intrusion detection systems to monitor network
traffic for signs of anomalous or suspicious activity. This may aid in
detection of attacks or malicious activity related to exploitation of latent
Symantec would like to thank Knut St. Osmundsen for reporting the deadlock
issue, Mike Czumak (@SecuritySift) for reporting the DLL Loading and Jan
Kadijk for reporting the Blind SQL Injection and working with us as we
addressed these issues.
BID: Security Focus, http://www.securityfocus.com, has assigned Bugtraq ID
(BID) to these issues for inclusion in the Security Focus vulnerability
CVE: These issues are candidates for inclusion in the CVE list
(http://cve.mitre.org), which standardizes names for security problems.
