EUVDB-ID: #VU98050
Risk: Medium
CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2024-41996
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to unnecessary validation of the public keys in the Diffie-Hellman Key Agreement Protocol when an approved safe prime is used. A remote attacker from the client side can trigger unnecessarily expensive server-side DHE modular-exponentiation calculations and cause asymmetric resource consumption, resulting in a denial of service (DoS) attack.
The vulnerability affects ClientSSL and ServerSSL profiles when configured with DHE ciphers.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
