VulniPulse record published
Summary
A flaw was found in the Quay config-tool's LDAP and SMTP validation functions. An attacker with config editor access can exploit these functions, which make outbound connections to user-supplied endpoints without proper IP or host filtering.
This allows the attacker to perform internal network reconnaissance from the Quay pod's network position, potentially mapping the internal network infrastructure. Red Hat severity: Low — CVSS 4.1 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N).
Weakness: CWE-918. Affected Red Hat products: Red Hat Quay 3.
Red Hat does not currently list a fixing RHSA for this CVE.
