Summary
SIDIS Prime before V4.0.400 is affected by multiple vulnerabilities in the components OPC UA and OpenSSL, that could allow an unauthenticated attacker with access to the network where SIDIS Prime is installed to reuse OPC UA client credentials, create a denial of service condition of the SIDIS Prime OPC UA client, or create a denial of service condition of the SIDIS Prime TLS service.
Siemens has released a new version of SIDIS Prime and recommends to update to the latest version.
Vulnerabilities 5
-
High 7.5
Segmentation fault in SSL_check_chain
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an i…

High 7.5
Infinite loop in BN_mod_sqrt() reachable when parsing certificates
The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or e…

High 7.5
Security Update for the OPC UA .NET Standard Stack
An infinite loop in OPC UA .NET Standard Stack 1.04.368 allows a remote attackers to cause the application to hang via a crafted message.

High 7.4
Insufficient Nonce Validation in Eclipse Milo Client
In OPC Foundation OPC UA .NET Standard codebase 1.4.357.28, servers do not create sufficiently random numbers in OPCFoundation.NetStandard.Opc.Ua before 1.4.359.31, which allows man in the middle attackers to reuse encrypted user credentials sent over the net…

Medium 5.9CVE-2020-1971 Public exploit
EDIPARTYNAME NULL pointer dereference
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equa…
