Technical details
This vulnerability (CVE-2026-82786) is classified as insufficiently protected credentials (CWE-522) affecting the Remote I/O Coupler Unit Server Type CPSN-MCB271-* in versions prior to 1.82. The root cause is weak credential storage mechanisms that allow sensitive authentication data to be restored from backup files. An attacker must have network access and moderate complexity conditions to exploit this, but does not require prior authentication. Successful exploitation allows an attacker to retrieve stored credentials, potentially enabling lateral movement within an industrial control network or unauthorized system access. A patch is available in version 1.82 and later.
