Siemens SIMATIC S7-1500 Observable Discrepancy (CVE-2023-0361)

A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to...

Siemens SIMATIC S7-1500 Observable Discrepancy (CVE-2021-33560)

Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side- channel attack against mpipowm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP. This plugin only works with...

Siemens SIMATIC S7-1500 Observable Discrepancy (CVE-2018-0495)

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

Siemens SIMATIC S7-1500 Observable Timing Discrepancy (CVE-2024-2236)

A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts. This plugin only works with Tenable.ot. Please visit...

Siemens SIMATIC S7-1500 Exposure of Sensitive Information to an Unauthorized Actor (CVE-2024-28834)

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLSPRIVKEYFLAGREPRODUCIBLE flag, it can result in a noticeable step in nonce...

Siemens SIMATIC S7-1500 Out-of-bounds Write (CVE-2019-3857)

An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way SSHMSGCHANNELREQUEST packets with an exit signal are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects t...

Siemens SIMATIC S7-1500 Exposure of Resource to Wrong Sphere (CVE-2019-12904)

In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. The C implementation is used on platforms where an assembly-language implementation is unavailable. NOTE: the vendor's position is...
