A vital safety vulnerability has been found in Rockwell Automation’s ControlLogix Ethernet communication modules, probably permitting distant attackers to execute arbitrary code on industrial management methods.
The vulnerability, tracked as CVE-2025-7353, impacts a number of ControlLogix Ethernet modules and carries a most CVSS rating of 9.8, indicating extreme safety implications for industrial automation environments.
Key Takeaways1. Essential flaw in Rockwell ControlLogix Ethernet modules as a result of enabled internet debugger agent.2. Attackers can remotely execute code, dump reminiscence, and management industrial methods.3. Replace instantly; implement community segmentation if patching is delayed.
Rockwell Automation printed the safety advisory on August 14, 2025, after discovering the flaw throughout inside testing procedures.
Insecure Default Configuration Flaw (CVE-2025-7353)
The CVE-2025-7353 vulnerability stems from an insecure default configuration within the web-based debugger (WDB) agent that is still enabled on manufacturing gadgets.
This debugging interface, meant for improvement functions, creates a big assault vector when left energetic in operational environments.
The vulnerability permits unauthenticated distant attackers to ascertain connections utilizing particular IP addresses to entry the WDB agent performance.
The flaw is classed beneath CWE-1188: Initialization of a Useful resource with an Insecure Default, highlighting the basic safety concern of delivery merchandise with debugging capabilities enabled by default.
The CVSS 3.1 vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H signifies that the vulnerability could be exploited over the community with low complexity, requires no privileges or person interplay, and supplies excessive affect throughout confidentiality, integrity, and availability.
The vulnerability impacts a number of ControlLogix Ethernet communication modules, together with 1756-EN2T/D, 1756-EN2F/C, 1756-EN2TR/C, 1756-EN3TR/B, and 1756-EN2TP/A fashions working firmware model 11.004 or beneath.
These modules function vital communication interfaces between ControlLogix programmable automation controllers (PACs) and Ethernet networks in industrial environments.
Profitable exploitation allows attackers to carry out reminiscence dumps, modify system reminiscence, and management the execution movement of the affected gadgets.
This degree of entry might probably enable attackers to govern industrial processes, entry delicate operational knowledge, or disrupt manufacturing operations.
The online-based debugger agent supplies low-level system entry usually reserved for approved improvement and upkeep personnel.

Mitigations
Rockwell Automation has launched firmware model 12.001 to deal with the vulnerability throughout all affected ControlLogix Ethernet modules.
Organizations ought to prioritize updating to this corrected model as the first mitigation technique. The replace disables the insecure default configuration of the WDB agent, eliminating the first assault vector.
For environments the place fast firmware updates usually are not possible, Rockwell Automation recommends implementing complete safety finest practices.
These embody community segmentation to isolate industrial management methods, implementation of correct firewall guidelines to limit entry to debugging interfaces, and steady monitoring of community visitors for suspicious actions.
Organizations also needs to conduct thorough safety assessments of their industrial automation infrastructure to determine comparable vulnerabilities in different methods.
