The vendor explicitly identifies these products as affected by this CVE.

  • Rockwell Automation ISaGRAF Workbench Versions 6.0 through 6.6.9 optional component of Schneider Electric SAGE RTU C3414 CPU (Current) Versions prior to C3414-500-S02K5_P5
  • Rockwell Automation ISaGRAF Workbench Versions 6.0 through 6.6.9 optional component of Schneider Electric SAGE RTU C3413 CPU (Obsolete CPU) All firmware versions
  • Rockwell Automation ISaGRAF Workbench Versions 6.0 through 6.6.9 optional component of Schneider Electric SAGE RTU C3412 CPU (Obsolete CPU) All firmware versions
Summary
ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Path Traversal vulnerability. A crafted malicious .7z exchange file may allow an attacker to gain the privileges of the ISaGRAF Workbench software when opened. If the software is running at the SYSTEM level, then the attacker will gain admin level privileges. User interaction is required for this exploit to be successful. Note: The CVSS score provided above is calculated in the context of SAGE RTU.
Remediation
Version C3414-500-S02K5_P5 of SAGE RTU CPU 3414 includes a mitigation for these vulnerabilities and is available for download here: https://www.sage-rtu.com/downloads.html Reboot of SAGE RTU is required after firmware upgrade. This mitigation disables the ISaGRAF listening TCP ports by default and provides an additional network service checkbox to allow customers to enable the ISaGRAF ETCP task, which will open the TCP listening ports to connect with ISaGRAF workbench when needed, and to disable the TCP listening ports when ISaGRAF Workbench development, debugging, and downloading tasks are complete. These vulnerabilities can only be exploited when users reopen the listening ports and connect with ISaGRAF workbench. These vulnerabilities only apply when a non-secure network is being used to perform development tasks in non-runtime applications. It is our recommendation to mitigate these vulnerabilities by performing all ISaGRAF workbench tasks on a secure network or on a private network when connecting to the device. OR If firmware is not upgraded to C3414-500-S02K5_P5, but customers are running firmware version C3414-500-S02K2 or above, then they should immediately apply the following mitigations to reduce the risk of exploit: If ISaGRAF is configured and in use, the built-in firewall can be used to disable ISaGRAF port 1131 and 1113 when the debugger is not in use. Use the following commands in the Firewall configuration to disable external access to ISaGRAF: Block in proto tcp from any to any port = 1131 Block in proto tcp from any to any port = 1113 If ISaGRAF is NOT configured and in use, the ISaGRAF port is by default not enabled and does not start automatically, therefore there is no impact of these vulnerabilities, and no further action is required by customers.

What, why and how

Rockwell Automation ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Path Traversal vulnerability. A crafted malicious .7z exchange file may allow an attacker to gain the privileges of the ISaGRAF Workbench software when opened. If the software is running at the SYSTEM level, then the attacker will gain admin level privileges. User interaction is required for this exploit to be successful.

What

Rockwell Automation ISaGRAF Workbench software versions 6.0 through 6.6.9 are affected by a Path Traversal vulnerability. A crafted malicious .7z exchange file may allow an attacker to gain the privileges of the ISaGRAF Workbench software when opened. If the software is running at the SYSTEM level, then the attacker will gain admin level privileges. User interaction is required for this exploit to be successful.

Why

Attacker-controlled path data is not constrained to the intended directory before the application accesses a file.

How

An attacker operating through local access may attempt exploitation without authentication after a user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
local access → Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-22 ↗

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'). The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SChangedScope: The attack can affect a component governed by a different security authority.CLowConfidentiality impact: A successful attack can cause a limited loss.ILowIntegrity impact: A successful attack can cause a limited loss.ALowAvailability impact: A successful attack can cause a limited loss.
Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.
