Informations from the vendor's website: "GENESIS32™ is the industry’s first and only fully scalable suite of OPC, SNMP, BACnet and Web-enabled HMI and SCADA applications." ####################################################################### Freeing of Arbitrary Memory: ====== Bug ====== GenBroker is a Windows service running on port 38080. The addresses and code snippets reported here are referred to GENESIS32 9.2. The service is affected by multiple freeing of initialized memory pointers and arbitrary locations because: - the functions that store the strings pointers read from the client automatically break the reading loop when the end of the packet is reached - these functions use malloc instead of calloc so the memory is not cleared - the functions that free the arrays don't know if and when the reading process stopped and so they call free() over all the elements specified by the attacker in his packet The exploitability of these vulnerabilities depends by how the attacker has corrupted the memory for forcing the freeing of arbitrary locations through the sending of valid packets before the malformed one. The service is multi-thread so there are many chances of exploitation. The following is the full list of vulnerable opcodes and the read/free functions to monitor (referred to version 9.2): 1) opcode 0x4b0: read loop: 0044ACC0 and 0044AD04 free loop: 004446B0 2) opcode 0x4b2: read loop: 0044B360 free loop: 004428F0 3) opcode 0x4b5: read loop: 0044C560 free loop: 00443090 4) function 0044C6B0 used by opcodes 0xDAE and 0xDB0. read loop: 0044c800 free loop: 00443160 5) opcodes 0x1BBC and 0x1BBD: read loop: 0044ca90 free loop: 004432a0 ####################################################################### =========== The Code =========== http://aluigi.org/poc/genesis_1.zip https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/17023-1.zip (genesis_1.zip) ####################################################################### Remote Integer Overflow: ====== Bug ====== GenBroker is a Windows service running on port 38080. The addresses and code snippets reported here are referred to GENESIS32 9.2. The service is affected by an integer overflow vulnerability during the handling of the opcodes 3f0, 138F,1390,1391,1392,1393, 1394, 1C86, 89a,89b, 450,451,454,455, 1C20,1C24 that make use of the function 0044d1c0. The problem is caused by the allocation of the memory needed for the creation of an array trusting the number of elements passed by the client. The resulting memory corruptions (like direct registry calls, memory locations calls, writing of data in arbitrary locations and so on) allow code execution. Fields in the packet: the format of the packets depend by the relative opcodes, the function 0044d1c0 reads a 32bit before the one used for the allocation. Vulnerable code: 0044D2A2 |.
