CVE-2020-7069

CVE-2020-7069 · Wrong ciphertext/tag in AES-CCM encryption for a 12 bytes IV

This page contains facts from public vulnerability sources. Check the original advisory before updating.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
