CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-24060 is a critical-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Automatedlogic (inferred from references). Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 10th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

CVE-2026-24060, published on 2026-03-21, is a critical vulnerability (CVSS 9.1, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) involving unencrypted transmission of service information in BACnet packets over the network. This flaw, tied to CWE-319 (Cleartext Transmission of Sensitive Information), affects systems using WebCTRL to receive updates from PLCs, where data such as File Start Position and File Data is exposed in plain text.
Any network-adjacent attacker can exploit this vulnerability without privileges or user interaction by sniffing BACnet traffic with tools like Wireshark's BACnet dissector filter to capture sensitive service information. Attackers can also intercept and modify packets or reverse engineer the proprietary format used for WebCTRL-PLC updates, resulting in high confidentiality and integrity impacts such as data theft or tampering.
Advisories including CISA's ICSA-26-078-08 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-078-08), the corresponding CSAF file (https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2026/icsa-26-078-08.json), and Automated Logic's security commitment page (https://www.automatedlogic.com/en/company/security-commitment/) provide details on mitigation steps.

Vulnerability Data
Service information is not encrypted when transmitted as BACnet packets over the wire, and can be sniffed, intercepted, and modified by an attacker. Valuable information such as the File Start Position and File Data can be sniffed from network traffic…

SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

A.8.21 mandates identifying/implementing network service security features (explicitly including encryption and connection controls), formulating rules that cover authentication/authorization/monitoring/VPNs, and ensuring providers do the same; this stops cleartext transmission from being exploitable in the large majority of network channels, with a bounded remainder (e.g. internal non-networked flows or unaddressed legacy protocols).
Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.
A.5.17 mandates secure transmission of authentication information, removing cleartext transmission of that specific sensitive data, but does not address other sensitive information transmitted in cleartext, so it removes only a subset of CWE-319 instances.
A.8.5 requires that passwords not be transmitted in cleartext, so applying it removes that specific instance of cleartext transmission, but it does not address other sensitive information sent in cleartext.
