Description

The version of Symantec Endpoint Protection (SEP) Client installed on the remote host is prior to 14.3. It is therefore affected by the following vulnerabilities:

- An elevation of privilege vulnerability exists. An authenticated, local attacker can exploit this by resetting ACLs on a file as a limited user while the tamper feature is disabled, to gain elevated privileges. (CVE-2020-5836)

- An elevation of privilege vulnerability exists. An authenticated, local attacker can exploit this by by writing to log files that are replaced by symbolic links to gain elevated privileges. (CVE-2020-5837)
