Schneider Modicon Ladder Logic Upload/Download

The Schneider Modicon with Unity series of PLCs use Modbus function code 90 0x5a to send and receive ladder logic. The protocol is unauthenticated, and allows a rogue host to retrieve the existing logic and to upload new logic. Two modes are supported: "SEND" and "RECV," which behave as one might...

Schneider Modicon Remote START/STOP Command

The Schneider Modicon with Unity series of PLCs use Modbus function code 90 0x5a to perform administrative commands without authentication. This module allows a remote user to change the state of the PLC between STOP and RUN, allowing an attacker to end process control by the PLC. This module is...

Bloody Valentine For Critical Infrastructure: EtherNet/IP Exploit Could Crash Devices

Security researchers made good on a promise to release new exploits for programmable logic controllers PLCs. The exploits include one targeting a flaw in the implementation of the EtherNet/IP Industrial Protocol used in many IP-enabled PLCs. The security hole, if left unaddressed, could enable a...

Cancun, Mexico

At Kaspersky Lab’s Security Analyst Summit last week, over 100 researchers and law enforcement officials converged in Cancun, Mexico over the course of five days to network and discuss a veritable cornucopia of security topics. Topics such as privacy, SCADA and PLC security, tracking cybercrimina...

CVE-2012-0929

Schneider Electric Modicon Quantum PLC is affected by CVE-2012-0929 due to multiple buffer overflows in the PLC’s FTP and HTTP servers. Remote attackers can trigger a denial of service by sending malformed requests to either service. The publicly available details show the impact as DoS with netw...

CVE-2012-0931

CVE-2012-0931 concerns Schneider Electric Modicon Quantum PLC. The issue is an authentication gap between the Unity software and the PLC, allowing remote attackers to cause a denial of service or potentially execute arbitrary code via unspecified vectors. Several connected sources (NVD, Tenable O...

CVE-2012-0930

The CVE-2012-0930 entry concerns the Schneider Electric Modicon Quantum PLC. All connected sources describe a Cross-Site Scripting (XSS) vulnerability in the Quantum PLC’s web context, enabling remote attackers to inject arbitrary web script or HTML via unspecified vectors. The affected component...

Ladder logic

The devices tested by the Basecamp Project included the D20 PLC by GE, The Modicon Quantum by Schneider Electric, Rockwell and Koyo Electronics. Each device was tested using a number of additional attack vectors. Researchers attempted to upload custom firmware or so-called “ladder logic” for the...

(Not) making the grade

The researchers working on Project Basecamp found significant security issues with programmable logic controller PLC they tested. Some PLCs were too brittle and insecure to even tolerate security scans and probing. The D20 ME PLC by General Electric – a widely deployed industrial system – fared t...

Security audits

A presentation on Project Basecamp was a highlight of the conference. The talk presented the findings of a volunteer-led security audit of leading programmable logic controllers PLCs. The audit found that decrepit hardware, buggy software and pitiful or nonexistent security features make thousand...

UPDATE: Looking For a 'FireSheep' Moment, Researchers Lay Bare Woeful SCADA Security

Miami, Florida – A no-holds barred presentation at the S4 Conference laid bare the woeful state of security for many industrial control systems that power the world’s critical infrastructure. Organizers have also cooperated with security scanning firms Rapid7 and Tenable to release modules for th...
