This vulnerability involves an out-of-bounds write in the CONPROSYS nano Series Remote I/O Coupler Unit (Server Type) CPSN-MCB271-* by Contec Co., Ltd. An attacker with network access and low privileges can send a specially crafted request that causes the device to perform an out-of-bounds write, leading to a denial-of-service condition. The vulnerability does not impact confidentiality or integrity but affects availability. The affected versions include all versions prior to 1.02, 1.61, and 1.82 as specified. No known exploits in the wild have been reported, and no patch or remediation information is provided in the available data.

The primary impact is a denial-of-service condition caused by an out-of-bounds write triggered remotely. There is no reported impact on confidentiality or integrity. The vulnerability requires low privileges and no user interaction, making it remotely exploitable over the network. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is provided in the available data. Until a patch is available, restrict network access to the affected devices and monitor for unusual behavior to mitigate potential denial-of-service conditions.
