A vulnerability has been reported in Wonderware InBatch and Foxboro I/A Series Batch, which can be exploited by malicious people to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the "lm_tcp" service, which can be exploited to cause a buffer overflow and e.g. write 16bits with the value 0 (0x0000) to an arbitrary memory location by sending a specially crafted packet to port 9001.
The vulnerability is reported in Wonderware InBatch version 9.0sp1 running "lm_tcp" version 9.0.0 0248.18.0.0 and is also reported in Wonderware InBatch 8.1 and I/A Series Batch 8.1. Other versions may also be affected.
Solution: Apply patches when available. See vendor's advisory for possible mitigation steps.
