Official Description

Multiple stack-based buffer overflows in IAO.EXE in the Intel Alert Originator Service in Symantec Alert Management System 2 (AMS2), as used in Symantec System Center (SSS); Symantec AntiVirus Server; Symantec AntiVirus Central Quarantine Server; Symantec AntiVirus (SAV) Corporate Edition 9 before 9.0 MR7, 10.0 and 10.1 before 10.1 MR8, and 10.2 before 10.2 MR2; Symantec Client Security (SCS) 2 before 2.0 MR7 and 3 before 3.1 MR8; and Symantec Endpoint Protection (SEP) before 11.0 MR3, allow remote attackers to execute arbitrary code via (1) a crafted packet or (2) data that ostensibly arrives from the MsgSys.exe process.

Technical Analysis

CVE-2009-1430 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

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-2009-1430. 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.
