PARTIAL Summary
Symantec Endpoint Protection (SEP) and Symantec Endpoint Protection Small Business Edition (SEP SBE), prior to 14.2 RU2 MP1 and prior to 14.2.5569.2100 respectively, may be susceptible to a privilege escalation vulnerability, which is a type of issue whereby an attacker may attempt to compromise the software application to gain elevated access to resources that are normally protected from an application or user.

- Restful Privilege Elevation Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.

description | The version of Symantec Endpoint Protection (SEP) Client installed on the remote host is 14.x prior to 14.2.5569.2100. It is, therefore, affected by multiple vulnerabilities: - A privilege escalation vulnerability exists. An unauthenticated, remote attacker can exploit this to compromise the software application to gain elevated access to resources that are normally protected from an application or user. (CVE-2020-5820, CVE-2020-5822, CVE-2020-5823) - A DLL injection vulnerability exists. An unauthenticated, local attacker can exploit this to execute their own code in place of legitimate code as a means to perform an exploit. (CVE-2020-5821) - A denial of service (DoS) vulnerability exists. An unauthenticated, remote attacker can exploit this issue to make the application stop responding.(CVE-2020-5824) - An arbitrary file write vulnerability exists. An unauthenticated, remote attacker can exploit this to overwrite existing files on the resident system without proper privileges. (CVE-2020-5825) - An out-of-bounds read error exists. An unauthenticated, remote attacker can exploit this to read memory outside of the bounds of the memory that had been allocated to the program. (CVE-2020-5826) Note that Nessus has not tested for this issue but has instead relied only on the application |
