CWE-119Published: April 5, 2011· Updated: Jun 16, 2026

10.0

CVSS v3.1

Official Description

Multiple stack-based buffer overflows in IGSSdataServer.exe 9.00.00.11063 and earlier in 7-Technologies Interactive Graphical SCADA System (IGSS) allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted (1) ListAll, (2) Write File, (3) ReadFile, (4) Delete, (5) RenameFile, and (6) FileInfo commands in an 0xd opcode; (7) the Add, (8) ReadFile, (9) Write File, (10) Rename, (11) Delete, and (12) Add commands in an RMS report templates (0x7) opcode; and (13) 0x4 command in an STDREP request (0x8) opcode to TCP port 12401.

Technical Analysis

CVE-2011-1567 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-2011-1567. 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.
