TITLE

ClearSCADA Buffer Overflow Vulnerability

DESCRIPTION

Use-after-free vulnerability in Control Microsystems ClearSCADA 2005, 2007, and 2009 before R2.3 and R1.4, as used in SCX before 67 R4.5 and 68 R3.9, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified long strings that trigger heap memory corruption. Control Microsystems is Schneider Electric, a global provider of SCADA hardware and software products. ClearSCADA is an integrated SCADA host platform that includes a rotation training engine, real-time database, web server, alarm processor and reporting software. There are several security vulnerabilities in ClearSCADA: 1. There is a heap-based buffer overflow for ClearSCADA applications, and a type heap overflow for overflow after release. Sending a legal message containing a very long string can trigger heap corruption. 2, ClearSCADA provides a WEB interface that supports HTTP and HTTPS. By default, the ClearSCADA server uses HTTP, which allows anyone to obtain plaintext authentication information by sniffing. 3. There is a reflective cross-site scripting attack on the WEB interface. With this vulnerability, an attacker can directly inject malicious code into a user's browser session. The parameter returned to the user is missing filtering. Attackers can exploit vulnerabilities for cross-site scripting attacks to obtain sensitive information or hijack user sessions. Control Microsystems ClearSCADA is prone to multiple remote vulnerabilities, including: 1. An information-disclosure vulnerability An attacker can exploit these issues to execute arbitrary code with elevated privileges, execute arbitrary script code within the context of the webserver, steal cookie-based authentication credentials, and gain access to sensitive information. Other attacks are also possible. The following products are affected: ClearSCADA 2005 ClearSCADA 2007 ClearSCADA 2009. ClearSCADA The application has a use error after release. ---------------------------------------------------------------------- Join Secunia @ FIRST Conference, 12-17 June, Hilton Vienna, Austria See to the presentation "The Dynamics and Threats of End-Point Software Portfolios" by Secunia's Research Analyst Director, Stefan Frei.
