Summary

Denial-of-service (DoS) vulnerability in Mitsubishi Electric MELSOFT transmission port

Details

MELSOFT transmission port (UDP/IP) of MELSEC iQ-R, iQ-F, Q, L, and F series provided by Mitsubishi Electric Coporation contains an uncontrolled resource consumption issue (CWE-400). When MELSOFT transmission port receives massive amount of data, resource consumption occurs and the port does not process the data properly. As a result, it may fall into a denial-of-service (DoS) condition. Mitsubishi Electric Corporation reported these vulnerabilities to JPCERT/CC to notify users of the solution through JVN.
