Vulnerability description
DayBreach CVE AI Research
CVE-2020-20949 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Bleichenbacher's attack on PKCS #1 v1.5 padding for RSA in STM32 cryptographic firmware library software expansion for STM32Cube (UM1924). The vulnerability can allow one to use Bleichenbacher's oracle attack to decrypt an encrypted ciphertext by making successive queries to the server using the vulnerable library, resulting in remote information disclosure.
