Descriptions
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.
Symantec Endpoint Protection (SEP) y Symantec Endpoint Protection Small Business Edition (SEP SBE), versiones anteriores a 14.2 RU2 MP1 y versiones anteriores a 14.2.5569.2100 respectivamente, pueden ser susceptibles a una vulnerabilidad de escalada de privilegios, que es un tipo de problema por el cual un atacante puede intentar comprometer la aplicación de software para conseguir un acceso elevado a los recursos que normalmente están protegidos de una aplicación o un usuario.
This vulnerability allows local attackers to escalate privileges on affected installations of Symantec Endpoint Protection. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the AvHostPlugin.dll. The issue results from the lack of proper validation of user-supplied data, which can result in a write before the start of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
