CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass authorization process.
The vulnerability exists due to improper implementation of SASL Quorum Peer authentication. The instance part in SASL authentication ID, which is listed in zoo.cfg server
list, is optional and if it's missing,
the authorization check will be skipped. As a
result an arbitrary endpoint could join the cluster and begin
propagating counterfeit changes to the leader, essentially giving it
complete read-write access to the data tree.
3) Incorrect default permissions (CVE-ID: CVE-2023-2976)
CWE-ID: CWE-276 - Incorrect Default Permissions
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
