CVE-2024-51504When using IPAuthenticationProvider in ZooKeeper Admin Server there is a possibility of Authentication Bypass by Spoofing -- this only impacts IP based authentication implemented in ZooKeeper Admin Server. Default configuration of client's IP address detection in IPAuthenticationProvider, which uses HTTP request headers, is weak and allows an attacker to bypass authentication via spoofing client's IP address in request headers. Default configuration honors X-Forwarded-For HTTP header to read client's IP address. X-Forwarded-For request header is mainly used by proxy servers to identify the client and can be easily spoofed by an attacker pretending that the request comes from a different IP address. Admin Server commands, such as snapshot and restore arbitrarily can be executed on successful exploitation which could potentially lead to information leakage or service availability issues. Users are recommended to upgrade to version 3.9.3, which fixes this issue.
CWE-290
No public exploit
Nothing published shows this CVE being exploited, which is not the same as ruling it out. nothing published in a year.
CVSS E:U
In RASP's scope with an upstream fix path, but nobody has published a working exploit. That is a statement about what has been published, not a finding that the defect is unreachable or unimportant.
| Decided by | no-exploit-published : A published working exploit for this candidate, not only a proof of concept, a forecast, or nothing at all |
|---|---|
| Finding | This CVE is not listed in CISA KEV, CISA Vulnrichment records no active exploitation, and no reviewed exploit catalogue carries an entry for it. Nobody has published something a stranger can run, so it is not a candidate for a rule ahead of the ones where somebody has; an upstream fix path does exist, so the remediation half of the candidacy still holds. This is a statement about what has been published, not about whether the defect is reachable or serious. |

1 metric
VRT selects the newest version's highest entry and
publishes it as cvssScore, newest rather than largest because scores are not comparable
across versions, and highest rather than first because the first entry is frequently a CNA placeholder
scoring 0.0 over NVD's own analysis.
