2) Information Exposure Through Timing Discrepancy

EUVDB-ID: #VU71993

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-4304

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain sensitive information.

The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.

To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.

Mitigation

Install update from vendor's website.
