Symantec Endpoint Protection clients place detected malware in quarantine as part of the intended product functionality. The quarantine logs can be exported for review by the user in a variety of formats including .CSV files. Prior to 14.0 MP1 and 12.1 RU6 MP7, the potential exists for file metadata to be interpreted and evaluated as a formula. Successful exploitation of an attack of this type requires considerable direct user-interaction from the user exporting and then opening the log files on the intended target client.

A version of the SymEvent Driver that shipped with Symantec Endpoint Protection 12.1 RU6 MP6 and earlier fails to properly sanitize logged-in user input. SEP 14.0 and later are not impacted by this issue. A non-admin user would need to be able to save an executable file to disk and then be able to successfully run that file. If properly constructed, the file could access the driver interface and potentially manipulate certain system calls. On all 32-bit systems and in most cases on 64-bit systems, this will result in a denial of service that will crash the system. In very narrow circumstances, and on 64-bit systems only, this could allow the user to run arbitrary code on the local machine with kernel-level privileges. This could result in a non-privileged user gaining privileged access on the local machine.

Prior to SEP 14 RU1 Symantec Endpoint Protection product can encounter an issue of Tamper-Protection Bypass, which is a type of attack that bypasses the real time protection for the application that is run on servers and clients.

Multiple SQL injection vulnerabilities in interface PHP scripts in the Manager component in Symantec Endpoint Protection (SEP) before 12.1.6 allow remote authenticated users to execute arbitrary SQL commands by leveraging the Limited Administrator role.

sysplant.sys in the Manager component in Symantec Endpoint Protection (SEP) before 12.1.6 allows local users to cause a denial of service (blocked system shutdown) by triggering an unspecified deadlock condition.

Multiple untrusted search path vulnerabilities in the Manager component in Symantec Endpoint Protection (SEP) before 12.1.6 allow local users to gain privileges via a Trojan horse DLL in an unspecified directory.

Buffer overflow in the sysplant driver in Symantec Endpoint Protection (SEP) Client 11.x and 12.x before 12.1 RU4 MP1b, and Small Business Edition before SEP 12.1, allows local users to execute arbitrary code via a long argument to a 0x00222084 IOCTL call.

The management console in Symantec Endpoint Protection (SEP) 11.0 before RU7-MP3 and 12.1 before RU2, and Symantec Endpoint Protection Small Business Edition 12.x before 12.1 RU2, does not properly validate input for PHP scripts, which allows remote authenticated users to execute arbitrary code via unspecified vectors.

The Manager service in the management console in Symantec Endpoint Protection (SEP) 12.1 before 12.1 RU1-MP1 allows remote attackers to conduct file-insertion attacks and execute arbitrary code by leveraging exploitation of CVE-2012-0294.

Directory traversal vulnerability in the Manager service in the management console in Symantec Endpoint Protection (SEP) 12.1 before 12.1 RU1-MP1 allows remote attackers to delete files via unspecified vectors.
