Vulnerability Data

When PROXY protocol v2 is used on the Unix domain socket path, roles derived from X.509 client certificates may not be validated against the configured tlsCATrusts allow-list. This can result in unintended role assignments following MONGODB-X509 authentication. Affected scenarios require…

more

local access to the proxy Unix domain socket and a valid X.509 certificate issued by a trusted certificate authority.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Bypass of X.509 role validation against tlsCATrusts allow-list enables unintended role/privilege assignment after MONGODB-X509 auth when local Unix socket + trusted cert is available.

prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
