CVE-2011-3490 in ScadaPro
Summary
by MITRE
Multiple stack-based buffer overflows in service.exe in Measuresoft ScadaPro 4.0.0 and earlier allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long command to port 11234, as demonstrated with the TF command.

The vulnerability identified as CVE-2011-3490 represents a critical stack-based buffer overflow in the service.exe component of Measuresoft ScadaPro version 4.0.0 and earlier. This flaw exists within the network service listening on port 11234 and specifically affects the handling of the TF command, which demonstrates how attackers can exploit this vulnerability to compromise system integrity. The buffer overflow occurs when the application fails to properly validate the length of incoming command data, allowing malicious inputs to overwrite adjacent memory locations on the stack. This type of vulnerability falls under CWE-121 Stack-based Buffer Overflow, which is classified as a fundamental weakness in software design that enables attackers to manipulate program execution flow through memory corruption.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, as it potentially enables remote code execution capabilities. When an attacker sends a specially crafted long command to the vulnerable port, the buffer overflow can overwrite return addresses and execution pointers stored in the stack memory, allowing malicious code to be executed with the privileges of the affected service. The attack vector is particularly concerning because it requires no authentication and can be executed remotely, making it an attractive target for threat actors seeking to compromise industrial control systems. This vulnerability directly aligns with ATT&CK technique T1203, which describes exploitation of remote services, and T1059, covering command and scripting interpreters.
The implications of this vulnerability are significant within industrial environments where ScadaPro systems are commonly deployed, as these systems control critical infrastructure components including power grids, water treatment facilities, and manufacturing processes. The potential for remote code execution means that attackers could gain persistent access to these systems and potentially cause physical damage through manipulation of operational parameters. Organizations running affected versions of Measuresoft ScadaPro should immediately implement network segmentation to isolate these services from general network access, disable unnecessary ports, and apply vendor patches as soon as they become available. Additionally, monitoring network traffic for unusual command patterns on port 11234 can help detect exploitation attempts. The vulnerability also highlights the importance of input validation and proper memory management practices in industrial control system software, emphasizing the need for regular security assessments and vulnerability management programs that address both known and emerging threats in operational technology environments.
