AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
LS ELECTRIC XBC-DN32U with OS version 01.80 has improper access control to its read prohibition feature, allowing a remote attacker to lock users out of reading data.
Vulnerability
The vulnerability exists in the LS ELECTRIC XBC-DN32U programmable logic controller (PLC) running operating system version 01.80. The device's read prohibition feature has improper access control, allowing the feature to be set remotely without proper authorization. [1]
Exploitation
An attacker can exploit this vulnerability remotely over the network without requiring authentication or user interaction. By sending a specially crafted request to the PLC, the attacker can enable the read prohibition feature, which locks out legitimate users from reading data from the device. [1]
Impact
Successful exploitation results in a denial-of-service condition where users are unable to read data from the PLC. This can lead to loss of visibility into the controlled process and potential operational disruption. [1]
Mitigation
No mitigation information is provided in the available reference. Users should contact LS ELECTRIC for firmware updates and consider network segmentation and access controls as compensating measures. [1]
