Official Description

Rockwell Automation's FactoryTalk System Services does not verify that a backup configuration archive is password protected.

Improper authorization in FTSSBackupRestore.exe may lead to the loading of malicious configuration archives.

User interaction is required for this vulnerability to be successfully exploited.

Technical Analysis

CVE-2023-2638 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 5.0.

From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
