Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Asymmetricrypt/asymmetricrypt, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
