CVE-2019-10953
ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO - Programmable Logic Controllers, multiple versions. Researchers have found some controllers are susceptible to a denial-of-service attack due
02 Description
ABB, Phoenix Contact, Schneider Electric, Siemens, WAGO - Programmable Logic Controllers, multiple versions. Researchers have found some controllers are susceptible to a denial-of-service attack due
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 3.39% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 88.2% of scored records. A rank, not a probability.
- NVD base score
- 7.5 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation
Fixes are available in Schneider Electric Modicon M221 firmware v1.10.0.0 and EcoStruxure Machine Expert – Basic v1.0 software (formerly SoMachine Basic) using either of the following options: Use this link to download the Machine Expert Basic software. Or run the Schneider Electric Software Update tool in order to download and install EcoStruxure Machine Expert – Basic v1.0 software. For additional information, see the Schneider Electric security notice SEVD-2019-045-01. (https://download.schneider-electric.com/files?p_Doc_Ref=SEVD-2019-045-01) Schneider Electric strongly recommends following industry cybersecurity best practices, such as: * Physical controls should be in place so no unauthorized person would have access to the ICS and safety controllers, peripheral equipment, or the ICS and safety networks. * All controllers should reside in locked cabinets and never be left in the “Program” mode. * All programming software should be kept in locked cabinets and should never be connected to any network other than the network for the devices it is intended. * All methods of mobile data exchange with the isolated network (e.g., CDs, USB drives, etc.) should be scanned before use in terminals or any node connected to these networks. * Laptops that have connected to any other network besides the intended network should never be allowed to connect to the safety or control networks without proper sanitation.
