GHSA-87mp-xc4x-x8rh · asymmetricrypt/asymmetricrypt Padding Oracle Vulnerability in RSA Encryption
Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.
The encryption and decryption process were vulnerable against the Bleichenbacher's attack, which is a padding oracle vulnerability disclosed in the 98'. The issue was about the wrong padding utilized, which allowed to retrieve the encrypted content. The OPENSSL_PKCS1_PADDING version, aka PKCS v1.5 was vulnerable (is the one set by default when using openssl_* methods), while the PKCS v2.0 isn't anymore (it's also called OAEP). A fix for this vulnerability was merged at https://github.com/Cosmicist/AsymmetriCrypt/pull/5/commits/a0318cfc5022f2a7715322dba3ff91d475ace7c6.
