Official Description

Buffer overflow in the sysplant driver in Symantec Endpoint Protection (SEP) Client 11.x and 12.x before 12.1 RU4 MP1b, and Small Business Edition before SEP 12.1, allows local users to execute arbitrary code via a long argument to a 0x00222084 IOCTL call.

Technical Analysis

CVE-2014-3434 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2014-3434. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
