TITLE

3S CoDeSys GatewayService Component Integer Overflow Vulnerability

DESCRIPTION

Integer overflow in the GatewayService component in 3S CoDeSys 3.4 SP4 Patch 2 allows remote attackers to execute arbitrary code via a large size value in the packet header, which triggers a heap-based buffer overflow. CoDeSys is a powerful PLC software programming tool that supports IEC61131-3 standard IL, ST, FBD, LD, CFC, SFC six PLC programming languages. The GatewayService has an integer overflow. The GatewayService uses the 32-bit value offset at the header 0x0c to specify the size of the received data. The program receives this value, increasing the number of 0x34 and allocating the amount of memory can cause an integer overflow. CmpWebServer is a component of the 3SRTESrv3 and CoDeSysControlService services for handling 8080 port connections. The function 0040f480 copies the input URI to a limited stack buffer, which can trigger a buffer overflow. 3S CoDeSys handles the Content-Length value in an HTTP POST request to trigger a null pointer reference. An integer overflow vulnerability exists in the GatewayService component in 3S CoDeSys 3.4 SP4 Patch 2 release. CoDeSys is prone to a stack-based buffer-overflow and an integer-overflow vulnerability. Attackers can exploit these issues to execute arbitrary code within the context of the application. Failed attacks may cause a denial-of-service condition. ---------------------------------------------------------------------- Secunia is hiring!

The vulnerabilities are confirmed in version 3.4 SP4 Patch 2. Other versions may also be affected. SOLUTION: Restrict access to trusted hosts only.
