TPM-Fail Attacks Against Cryptographic Coprocessors
Really interesting research: TPM-FAIL: TPM meets Timing and Lattice Attacks, by Daniel Moghimi, Berk Sunar, Thomas Eisenbarth, and Nadia Heninger. Abstract: Trusted Platform Module TPM serves as a hardware-based root of trust that protects cryptographic keys from privileged system and physical...
CVE-2019-15802
An issue was discovered on Zyxel GS1900 devices with firmware before 2.50AAHH.0C0. The firmware hashes and encrypts passwords using a hardcoded cryptographic key in salutilstrencrypt in libsal.so.0.0. The parameters salt, IV, and key data are used to encrypt and decrypt all passwords using AES256...

CVE-2019-15802
Affected product: Zyxel GS1900 switches. Vulnerability: firmware before 2.50(AAHH.0)C0 uses a hardcoded cryptographic key in libsal.so.0.0 to encrypt passwords via AES-256 CBC; the salt, IV, and key data are used to encrypt/decrypt all passwords, including those in config backups embedded in the ...
Researchers Discover TPM-Fail Vulnerabilities Affecting Billions of Devices
A team of cybersecurity researchers today disclosed details of two new potentially serious CPU vulnerabilities that could allow attackers to retrieve cryptographic keys protected inside TPM chips manufactured by STMicroelectronics or firmware-based Intel TPMs. Trusted Platform Module TPM is a...
Signature validation bypass in XmlSecLibs
Rob Richards XmlSecLibs, all versions prior to v3.0.3, as used for example by SimpleSAMLphp, performed incorrect validation of cryptographic signatures in XML messages, allowing an authenticated attacker to impersonate others or elevate privileges by creating a crafted XML message...
CVE-2019-16208
Password-based encryption PBE algorithm, of Brocade SANnav versions before v2.0, has a weakness in generating cryptographic keys that may allow an attacker to decrypt passwords used with several services Radius, TACAS, etc...

SimpleSAMLphp Input Validation Error Vulnerability
SimpleSAMLphp is a set of PHP authentication applications that implement the SAML 2.0 service provider and identity provider features . A security vulnerability exists in SimpleSAMLphp that stems from the program's failure to properly validate cryptographic signatures in XML files. An attacker ca...
GHSA-RC75-CF5C-MXVH Use of Cryptographically Weak Pseudo-Random Number Generator in org.pac4j:pac4j-saml
The SAML identifier generated within SAML2Utils.java was found to make use of the apache commons-lang3 RandomStringUtils class which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong. This issue only affects the 3.X release of pac4j-saml...
