1. EXECUTIVE SUMMARY
- CVSS v3 9.8
- ATTENTION: Exploitable remotely/low attack complexity
- Vendor: Rockwell Automation
- Equipment: FactoryTalk Activation Manager
- Vulnerabilities: Out-of-Bounds Write
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could result in a buffer overflow and allow the attacker to gain full access to the system.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of Factory Talk are affected:
- Factory Talk: V4.00 (Utilizes Wibu-Systems CodeMeter <7.60c)
3.2 Vulnerability Overview
3.2.1 OUT-OF-BOUNDS WRITE CWE-787
Rockwell Automation FactoryTalk Activation Manager and Studio 5000 Logix Designer uses the affected Wibu-Systems’ products which internally use a version of libcurl that is vulnerable to a buffer overflow attack if curl is configured to redirect traffic through a SOCKS5 proxy. A malicious proxy can exploit a bug in the implemented handshake to cause a buffer overflow. If no SOCKS5 proxy has been configured, there is no attack surface.
CVE-2023-38545 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
3.2.2 OUT-OF-BOUNDS WRITE CWE-787
Rockwell Automation FactoryTalk Activation Manager and Studio 5000 Logix Designer uses the affected Wibu-Systems’ products which contain a heap buffer overflow vulnerability in Wibu CodeMeter Runtime network service up to Version 7.60b that allows an unauthenticated, remote attacker to achieve RCE and gain full access of the host system.
