Overview
Symantec Endpoint Protection (SEP) was susceptible to a number of security findings that could potentially result in an authorized but less privileged user gaining elevated access to the Management Console. SEP Client security mitigations can potentially be bypassed allowing arbitrary code execution on a targeted client.

Details
The management console for SEPM contained a cross-site request forgery vulnerability that was the result of an insufficient security check in SEPM. An authorized but less-privileged user could potentially include arbitrary code in authorized logging scripts. When submitted to SEPM, successful execution could possibly result in the user gaining unauthorized elevated access to the SEPM management console with application privileges.
There was a SQL injection found in SEPM that could have allowed an authorized but less-privileged SEPM operator to potentially elevate access to administrative level on the application.
The sysplant driver is loaded as part of the Application and Device Control (ADC) component on a SEP client if ADC is installed and enabled on the client. A previous security update to this driver did not sufficiently validate or protect against external input. Successfully bypassing security controls could potentially result in targeted arbitrary code execution on a client system with logged-on user privileges. Exploitation attempts of this type generally use known methods of trust exploitation requiring enticing a currently authenticated user to access a malicious link or open a malicious document in a context such as a website or in an email.
NOTE: Customers not using ADC are not impacted by the client issue, CVE-2015-8154.
Symantec Response
Symantec product engineers have addressed these issues in SEP 12.1-RU6-MP4. Customers should update to RU6-MP4 as soon as possible to address these issues.
Please do upgrade to take advantage of many fixes and improvement, and to remain safe!
With thanks and best regards,
