Description
The version of Symantec Endpoint Protection Client running on the remote host is 12.1 prior to 12.1 RU6 MP4. It is, therefore, affected by a remote code execution vulnerability due to insecure permissions for the SysPlant.sys driver. A remote attacker can exploit this, via a crafted HTML document, to execute arbitrary code.

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.\n\n \n\nNOTE: Customers not using ADC are not impacted by the client issue, CVE-2015-8154. See Mitigations below for information on disabling the ADC driver or uninstalling ADC. \n \n \n\n \n\n### MITIGATION\n\n \n\nAs a workaround against the client issue, CVE-2015-8154, SEP administrators can disable the ADC driver or uninstall ADC in SEP 12.1 by following one of these options \n \nOption 1 for SEP 12.1: Disable the Application and Device Control driver \n \n**Note:** Deploying an Application and Device Control (ADC) policy is not sufficient to re-enable the driver after it has been disabled. Repairing the installation, or upgrading to a later version, will re-enable the sysplant driver automatically. \n \n\n 1. From the Symantec Endpoint Protection Management (SEPM) console, withdraw the Application and Device Control policy (if applicable).\n 2. Disable or configure Tamper Protection to allow the process for any tools or scripts used. \n[How to disable Tamper Protection in Symantec Endpoint Protection 12.1](<http://www.symantec.com/docs/TECH192023>)\n 3. At the local client, open a Windows command shell with administrative privileges.\n 4. Enter the following command: \n \nsc config sysplant start= disabled \n \n 5. Restart the client computer.\n 6. From the SEPM console, enable Tamper Protection.\n\n \nOption 2 for SEP 12.1: Uninstall Application and Device Control \n \n\n 1. From the SEPM console, click **Admin > Install Packages**, click **Client Install Feature Set**, and select **Add Client Install Feature Set**.\n 2. Choose to remove Application and Device Control, and click **OK**.\n 3. Navigate to Client Groups and select **Add Install Packages**.\n 4. Uncheck **Maintain Feature Set**, and select the newly created feature set, once for 32-bit and once for 64-bit. \nAll SEP clients are moved to that new feature set without the ADC component installed.\n\n \n\n**Symantec Response** \nSymantec 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.\n\n \n\nSymantec is not aware of exploitation of or adverse customer impact from this issue.\n\n \n\n**Update Information** \nSymantec Endpoint Protection Manager 12.1-RU6-MP4 is available from [Symantec File Connect](<https://symantec.flexnetoperations.com/>).\n\n \n\n**Best Practices**\n\n \n\nAs part of normal best practices, Symantec strongly recommends the following:\n\n \n\n * Restrict access to administrative or management systems to authorized privileged users.\n\n * Restrict remote access, if required, to trusted/authorized systems only.\n\n * Run under the principle of least privilege where possible to limit the impact of potential exploit.\n\n * Keep all operating systems and applications current with vendor patches.\n\n * Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications to provide multiple points of detection and protection to both inbound and outbound threats.\n\n * Deploy network- and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.\n\n### ACKNOWLEDGEMENTS\n\n \n\nSymantec would like to thank Anatoly Katyushin** **with Kaspersky Labs [https://www.kaspersky.com](<https://www.kaspersky.com/>), for finding and reporting CVE-2015-8152, CVE-2015-8153 and working closely with Symantec as they were addressed.\n\nSymantec would like to thank enSilo Research Team, [https://www.ensilo.com](<https://www.ensilo.com/>), for reporting CVE-2015-8154 and working closely with Symantec as it was addressed.\n\n### REVISION\n\n \n\n07/20/2016 - NOTE: CVE-2015-8154 addresses the vulnerability referenced by EnSilo in their [blog posting](<http://breakingmalware.com/vulnerabilities/captain-hook-pirating-avs-bypass-exploit-mitigations/#more-911>) published on July 19, 2016. \n \n03/18/2016 - Added Disable or Uninstall options and instructions for the ADC driver, CVE-2015-8154 in the SEP 12.1 Client\n", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "baseScore": 8.8, "privilegesRequired": "LOW", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "userInteraction": "NONE", "version": "3.0"}, "impactScore": 5.9}, "published": "2016-03-17T08:00:00", "type": "symantec", "title": "Symantec Endpoint Protection Multiple Security Issues", "bulletinFamily": "software", "cvss2": {"severity": "HIGH", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "COMPLETE", "availabilityImpact": "COMPLETE", "integrityImpact": "COMPLETE", "baseScore": 9.3, "vectorString": "AV:N/AC:M/Au:N/C:C/I:C/A:C", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 10.0, "obtainUserPrivilege": false}, "cvelist": ["CVE-2015-8152", "CVE-2015-8153", "CVE-2015-8154"], "modified": "2020-03-05T20:09:29", "id": "SMNTC-1354", "href": "", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}]}
