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.\n\nFor example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.","state":0,"publishedAt":"2023-02-08T22:31:42+00:00","modifiedAt":"2026-09-10T03:50:07.8662035+00:00","affected":[{"ecosystem":"crates.io","name":"openssl-src","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"111.25.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"crates.io","name":"openssl-src","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"300.0.0"},{"kind":"fixed","version":"300.0.12"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2022-4304","https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2023-0003","https://rustsec.org/advisories/RUSTSEC-2023-0007.html","https://security.gentoo.org/glsa/202402-08","https://www.openssl.org/news/secadv/20230207.txt"],"sourceUrl":"https://github.com/advisories/GHSA-p52g-cm5j-mjv4","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-p52g-cm5j-mjv4","identifiers":["GHSA-p52g-cm5j-mjv4","CVE-2022-4304","RUSTSEC-2023-0007"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
