CVE-2019-13537Network attack vector

Unauthenticated server crash via stack buffer overflow

Published Jan 14, 2020 · Updated Aug 4, 2024

Stack-based buffer overflow in AVEVA Plant SCADA's IEC870IP driver 4.14.02 and earlier allows remote attackers to crash the server. AVEVA has not disclosed which IEC 60870-5-104 message field or driver routine writes beyond the stack buffer. The protocol provides no authentication, so network access to the IEC870IP service is sufficient; reported impact is limited to a server crash.
