Vulnerability identifier: #VU62669
Vulnerability risk: Medium
Exploitation vector: Local network
Exploit availability: No
The vulnerability allows a remote attacker to read or modify data within an IPsec IKEv2 VPN tunnel.
The vulnerability exists due to improper implementation of Galois/Counter Mode (GCM) ciphers in an IPsec VPN library. A remote attacker can perform MitM attack by intercepting a sufficient number of encrypted messages across an affected IPsec IKEv2 VPN tunnel and then using cryptanalytic techniques to break the encryption.
