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. For 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.","evidence":"cve:CVE-2022-4304","products":[{"name":{"value":"OpenSSL","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"unknown","structured":{"id":"CVE-2022-4304","aliases":["CVE-2022-4304"],"metrics":[{"other":{"type":"https://www.openssl.org/policies/secpolicy.html","content":{"text":"MODERATE"}},"format":"other"}],"affected":[{"vendor":"OpenSSL","product":"OpenSSL","versions":[{"status":"affected","version":"3.0.0","lessThan":"3.0.8","versionType":"semver"},{"status":"affected","version":"1.1.1","lessThan":"1.1.1t","versionType":"custom"},{"status":"affected","version":"1.0.2","lessThan":"1.0.2zg","versionType":"custom"}],"defaultStatus":"unaffected"}],"modified":"2026-10-14T14:17:49.943Z","provider":"cve","references":["https://www.openssl.org/news/secadv/20230207.txt","https://security.gentoo.org/glsa/202402-08"],"provider_metadata":{"adp":[{"title":"CVE Program Container","references":[{"url":"https://www.openssl.org/news/secadv/20230207.txt","name":"OpenSSL Advisory","tags":["vendor-advisory","x_transferred"]},{"url":"https://security.gentoo.org/glsa/202402-08","tags":["x_transferred"]},{"url":"https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2023-0003"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-04T19:14:12.161Z"}},{"title":"CISA ADP Vulnrichment","metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.9,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"HIGH","availabilityImpact":"NONE","privilegesRequired":"NONE","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"id":"CVE-2022-4304","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2025-03-06T15:57:19.589862Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-203","description":"CWE-203 Observable Discrepancy"}]}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-08-27T20:32:52.408Z"}},{"affected":[{"vendor":"Siemens","product":"SCALANCE W1750D (JP)","versions":[{"status":"affected","version":"0","lessThan":"V8.10.0.9","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SCALANCE W1750D (ROW)","versions":[{"status":"affected","version":"0","lessThan":"V8.10.0.9","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SCALANCE W1750D (USA)","versions":[{"status":"affected","version":"0","lessThan":"V8.10.0.9","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SIMATIC S7-1500 CPU 1518-4 PN/DP MFP","versions":[{"status":"affected","version":"V3.1.0","lessThan":"V3.1.5","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SIMATIC S7-1500 CPU 1518-4 PN/DP MFP","versions":[{"status":"affected","version":"V3.1.0","lessThan":"V3.1.5","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP","versions":[{"status":"affected","version":"V3.1.0","lessThan":"V3.1.5","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP","versions":[{"status":"affected","version":"V3.1.0","lessThan":"V3.1.5","versionType":"custom"}],"defaultStatus":"unknown"},{"vendor":"Siemens","product":"SIMATIC S7-1500 TM MFP -
