An authentication management application installed on the remote host is affect by an information disclosure vulnerability.


The version of Oracle Access Manager installed on the remote host is affected by an information disclosure vulnerability in the Web Server Plugin subcomponent due to multiple flaws that exist in the bundled OpenSSL library, specifically in the aesni_cbc_hmac_sha1_cipher() function within file crypto/evp/e_aes_cbc_hmac_sha1.c and in the aesni_cbc_hmac_sha256_cipher() function within file crypto/evp/e_aes_cbc_hmac_sha256.c, which are triggered when the connection uses an AES-CBC cipher and AES-NI is supported by the server. A man-in-the-middle attacker can exploit these flaws to conduct a padding oracle attack, resulting in the ability to decrypt the network traffic.
