CVE-2019-0201

25
FAUCET Score

CVE-2019-0201 describes an information disclosure vulnerability in Apache ZooKeeper versions 1.0.0 to 3.4.13 and 3.5.0-alpha to 3.5.4-beta, also impacting products from Debian, NetApp, Oracle, and Red Hat. The getACL() command, lacking proper permission checks, inadvertently reveals unsalted hash values used for Digest Authentication to unauthenticated or unprivileged users. This medium-severity vulnerability (CVSS 5.9) has a high confidentiality impact, as an attacker can remotely obtain sensitive authentication hashes with low attack complexity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
