The function decides whether a password is required by issuing an empty AUTH command to Redis and treats only a WRONGPASS error as meaning that a password is required; any other error, such as LOADING while a dataset is being loaded, MASTERDOWN during replication failover, or OOM under memory pressure, causes the client to be treated as authenticated. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected." } ], "affected": [ { "vendor": "FalkorDB", "product": "FalkorDB", "collectionURL": "https://github.com/FalkorDB/FalkorDB", "repo": "https://github.com/FalkorDB/FalkorDB", "modules": [ "Bolt protocol endpoint" ], "programFiles": [ "src/bolt/bolt_api.c" ], "programRoutines": [ { "name": "is_authenticated" } ], "cpes": [ "cpe:2.3:a:falkordb:falkordb:*:*:*:*:*:*:*:*" ], "defaultStatus": "unaffected", "versions": [ { "version": "0", "lessThan": "4.20.0", "status": "affected", "versionType": "semver" } ] } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-287", "description": "CWE-287 Improper Authentication" } ] } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N", "baseScore": 9.2, "baseSeverity": "CRITICAL" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.1, "baseSeverity": "HIGH" } } ], "solutions": [ { "lang": "en", "value": "Upgrade FalkorDB to version 4.20.0 or later.
