| CVE-2026-63550 | 1 Mz-automation | 1 Libiec61850 | 2026-07-31 | 6.5 Medium |
| The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages. When a crafted BER-encoded element is received over an established MMS session (TCP port 102), the decoder may advance its internal read position incorrectly, leading to a heap out-of-bounds read. This condition causes the MMS handling process to terminate unexpectedly, resulting in a denial-of-service. | ||||
| CVE-2026-65421 | 1 Mz-automation | 1 Libiec61850 | 2026-07-31 | 6.5 Medium |
| The MMS BER decoder contains a flaw in decoding fixed-width BER fields (boolean/integer): an attacker-supplied length value is not validated, causing a read past the end of a heap buffer. This leads to termination of the MMS service process and a denial-of-service condition. | ||||
| CVE-2026-66364 | 1 Mz-automation | 1 Libiec61850 | 2026-07-31 | 6.5 Medium |
| The GOOSE payload parser contains a boundary handling flaw that can be triggered by a single unauthenticated Layer 2 multicast frame on the process bus. When processing specific payload fields, an attacker controlled inner element length may exceed its enclosing length, causing the parser to over read by one byte. This out-of-bounds read reliably terminates the subscriber process, resulting in a denial-of-service condition. | ||||
| CVE-2026-66360 | 1 Mz-automation | 1 Libiec61850 | 2026-07-31 | 7.5 High |
| The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This condition occurs before MMS session establishment, a crafted TCP/102 connection attempt can trigger the issue. The resulting over read causes the process to terminate, leading to a denial of service condition. | ||||
| CVE-2026-50039 | 1 Mz-automation | 1 Libiec61850 | 2026-07-24 | 7.5 High |
| The affected product is vulnerable to a stack-based buffer overflow, which may allow an attacker to cause a memory corruption via a Read Request. | ||||
| CVE-2026-49035 | 1 Mz-automation | 1 Libiec61850 | 2026-07-24 | 8.1 High |
| The affected product is vulnerable to a heap-based buffer overflow via a crafted MMS Initiate request. Remote code execution (RCE) has been demonstrated when ASLR is disabled; memory corruption or denial of service may occur in configurations where ASLR is enabled. | ||||
| CVE-2026-50103 | 1 Mz-automation | 1 Libiec61850 | 2026-07-24 | 6.5 Medium |
| A NULL pointer dereference in the L2 GOOSE and R-GOOSE shared parser, which may allow a network-adjacent attacker to crash a subscribing application by sending a crafted GOOSE frame containing a malformed TLV value. | ||||
| CVE-2026-50032 | 1 Mz-automation | 1 Libiec61850 | 2026-07-24 | 7.5 High |
| A NULL pointer dereference in the MMS Write Named Variable List handler, which may allow a network adjacent attacker to crash the server by sending a WriteRequest with an empty listOfData field. | ||||
| CVE-2026-16002 | 1 Mz-automation | 1 Lib60870 | 2026-07-24 | 8.2 High |
| The affected product is vulnerable to an Out-of-bounds read, which may allow an attacker to crash the parsing process and cause a denial of service. | ||||
