VAR-201811-0100

Vulnerability from variot - Updated: 2023-12-18 12:00

When processing project files in Omron CX-Supervisor Versions 3.4.1.0 and prior and tampering with the value of an offset, an attacker can force the application to read a value outside of an array. Provided by OMRON Corporation CX-Supervisor Contains the following multiple vulnerabilities: * * Buffer overflow (CWE-119) - CVE-2018-17905 Processing a specially crafted project file causes memory corruption * * Read out of bounds (CWE-125) - CVE-2018-17907  Reading out-of-array values by processing a specially crafted project file * * Use of freed memory (Use-after-free) (CWE-416) - CVE-2018-17909 Processing arbitrary crafted project files results in arbitrary code execution * * Bad type conversion or cast (Incorrect Type Conversion or Cast) (CWE-704) - CVE-2018-17913 Processing arbitrary crafted project files results in arbitrary code executionA remote attacker could execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OMRON CX-Supervisor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the handling of SCS files. By manipulating a document's elements an attacker can trigger a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. The Omron CX-Supervisor is a visual machine controller from Omron, Japan. Omron CX-Supervisor is prone to the following security vulnerabilities: 1. Multiple remote code-execution vulnerabilities 2. A memory-corruption vulnerability 3

Provided by OMRON Corporation CX-Supervisor Contains the following multiple vulnerabilities: * * Buffer overflow (CWE-119) - CVE-2018-17905 Processing a specially crafted project file causes memory corruption * * Read out of bounds (CWE-125) - CVE-2018-17907 \uf0b7 Reading out-of-array values by processing a specially crafted project file * * Use of freed memory (Use-after-free) (CWE-416) - CVE-2018-17909 Processing arbitrary crafted project files results in arbitrary code execution * * Bad type conversion or cast (Incorrect Type Conversion or Cast) (CWE-704) - CVE-2018-17913 Processing arbitrary crafted project files results in arbitrary code executionA remote attacker could execute arbitrary code. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OMRON CX-Supervisor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the handling of SCS files. By manipulating a document\u0027s elements an attacker can trigger a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. The Omron CX-Supervisor is a visual machine controller from Omron, Japan. Omron CX-Supervisor is prone to the following security vulnerabilities:\n1. Multiple remote code-execution vulnerabilities\n2. A memory-corruption vulnerability\n3",
