Prior to version 0.6.2, a security vulnerability in Soft Serve could allow an unauthenticated, remote attacker to bypass public key authentication when keyboard-interactive SSH authentication is active, through the `allow-keyless` setting, and the public key requires additional client-side verification for example using FIDO2 or GPG. This is due to insufficient validation procedures of the public key step during SSH request handshake, granting unauthorized access if the keyboard-interaction mode is utilized. An attacker could exploit this vulnerability by presenting manipulated SSH requests using keyboard-interactive authentication mode. This could potentially result in unauthorized access to the Soft Serve. Users should upgrade to the latest Soft Serve version `v0.6.2` to receive the patch for this issue. To workaround this vulnerability without upgrading, users can temporarily disable Keyboard-Interactive SSH Authentication using the `allow-keyless` setting."}],"source":{"advisory":"GHSA-mc97-99j4-vm2v","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T19:52:11.366Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/charmbracelet/soft-serve/security/advisories/GHSA-mc97-99j4-vm2v","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/charmbracelet/soft-serve/security/advisories/GHSA-mc97-99j4-vm2v"},{"name":"https://github.com/charmbracelet/soft-serve/issues/389","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/charmbracelet/soft-serve/issues/389"},{"name":"https://github.com/charmbracelet/soft-serve/commit/407c4ec72d1006cee1ff8c1775e5bcc091c2bc89","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/charmbracelet/soft-serve/commit/407c4ec72d1006cee1ff8c1775e5bcc091c2bc89"},{"name":"https://github.com/charmbracelet/soft-serve/releases/tag/v0.6.2","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/charmbracelet/soft-serve/releases/tag/v0.6.2"}]},{"affected":[{"vendor":"charmbracelet","product":"soft-serve","cpes":["cpe:2.3:a:charmbracelet:soft-serve:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThan":"0.6.2","versionType":"custom"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-19T18:37:09.312902Z","id":"CVE-2023-43809","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-20T14:51:49.413Z"}}]}}
