CVE-2023-41327 Detail

Description

WireMock is a tool for mocking HTTP services. WireMock can be configured to only permit proxying (and therefore recording) to certain addresses. This is achieved via a list of allowed address rules and a list of denied address rules, where the allowed list is evaluated first. Until WireMock Webhooks Extension 3.0.0-beta-15, the filtering of target addresses from the proxy mode DID NOT work for Webhooks, so the users were potentially vulnerable regardless of the `limitProxyTargets` settings. Via the WireMock webhooks configuration, POST requests from a webhook might be forwarded to an arbitrary service reachable from WireMock’s instance. For example, If someone is running the WireMock docker Container inside a private cluster, they can trigger internal POST requests against unsecured APIs or even against secure ones by passing a token, discovered using another exploit, via authentication headers. This issue has been addressed in versions 2.35.1 and 3.0.3 of wiremock. Wiremock studio has been discontinued and will not see a fix. Users unable to upgrade should use external firewall rules to define the list of permitted destinations.


Severity



CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  5.4 MEDIUM
Vector:  CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  4.6 MEDIUM
Vector:  CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
