Description
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.

Impact

A flaw exists in Quay's config-tool LDAP and SMTP validation functions that allows an attacker with configuration‑editor privileges to cause the tool to make outbound connections to arbitrary endpoints without filtering the target IP or hostname. The lack of host or IP validation effectively creates a server‑side request forgery (SSRF) that can be leveraged to probe internal network services, disclose server addresses, and map the internal infrastructure. The vulnerability results in a moderate breach of confidentiality and network visibility but does not directly grant code execution.

Affected Systems

The affected system is Red Hat Quay version 3. No additional specific version details are provided beyond the product identifier.

Risk and Exploitability

The CVSS score of 4.1 indicates a moderate risk. An attacker must already possess configuration‑editor rights, which typically implies elevated access within the environment. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, suggesting no known mass exploitation. The most likely attack vector is an insider or compromised account with config‑editor privileges initiating a malicious or misconfigured LDAP/SMTP validation request to a crafted internal endpoint, enabling internal network reconnaissance from the Quay pod's network position.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade to the latest Red Hat Quay release that includes the config‑tool fix following the vendor advisory
  • Apply the vendor‑issued security patch or configuration fix for Quay/config‑tool
  • If a patch cannot be applied immediately, restrict the set of users who have configuration‑editor permissions to a trusted subset
  • Configure network policies or firewall rules to block unintended outbound connections from the Quay pod, minimizing SSRF exposure
  • Implement strict host or IP validation in the LDAP and SMTP validation routines to prevent connections to untrusted endpoints
