Cisco Secure Email Secure/Multipurpose Internet Mail Extensions Ciphertext Decryption Vulnerabilities

Cisco released an advisory for S/MIME ciphertext decryption flaws in Secure Email that could let unauthenticated remote attackers recover plaintext via machine-in-the-middle.

Multiple vulnerabilities in the S/MIME decryption functionality of Cisco Secure Email stem from insufficient validation of message integrity. An unauthenticated remote attacker could intercept and modify traffic between email gateways using a machine-in-the-middle technique to obtain plaintext from encrypted messages. No workarounds are available; no CVE identifiers or exploitation status were included in the advisory text.
