Prior to 0.62.6, the USERAUTH_REQUEST path reached from server::run_stream in russh/src/server/encrypted.rs increments self.common.auth_attempts but never compares it with server::Config.max_auth_attempts. An unauthenticated remote client can continue submitting authentication requests on one connection beyond the configured cap, bypassing the deployment's attempt-limiting policy and increasing online guessing opportunity and backend authentication workload. This issue is fixed in version 0.62.6.","cvssScore":3.7,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-307"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Eugeny/russh/commit/f8fd0b11a393364dc7f01a182482d86adafdd653","tags":[]},{"url":"https://github.com/Eugeny/russh/releases/tag/v0.62.6","tags":[]},{"url":"https://github.com/Eugeny/russh/security/advisories/GHSA-g6xm-f9xp-qq35","tags":[]}],"exploitRefs":[{"url":"https://github.com/Eugeny/russh/commit/f8fd0b11a393364dc7f01a182482d86adafdd653","tags":[]},{"url":"https://github.com/Eugeny/russh/releases/tag/v0.62.6","tags":[]},{"url":"https://github.com/Eugeny/russh/security/advisories/GHSA-g6xm-f9xp-qq35","tags":[]}],"hasPoc":true,"ai":null}
