Lib60870
Monthly
Denial-of-service in MZ Automation's lib60870, an open-source IEC 60870-5-101/104 telecontrol protocol library used in ICS/SCADA systems, allows remote attackers to crash the message-parsing process via a malformed protocol frame that triggers an out-of-bounds read (CWE-125). The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated network exploitation with high availability impact and limited confidentiality exposure. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.
An issue was discovered in lib60870 v2.3.2. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
