Red Hat Red Hat OpenStack Platform 18.0 vulnerabilities

A flaw was found in openstack-network-exporter. The HTTP server within the component is configured without essential timeout settings, such as ReadHeaderTimeout. This vulnerability allows an unauthenticated, remote attacker to initiate multiple slow HTTP header connections. By trickling header bytes, the attacker can exhaust server resources, specifically file descriptors, leading to a Denial of Service (DoS) that prevents legitimate Prometheus metric scraping and alerting.

A flaw was found in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection. The shared OCAPI request helper disables TLS certificate validation on every request and the modules expose no parameter to re-enable it, while sending HTTP Basic-Auth credentials to an https endpoint. An attacker positioned on the network path between the Ansible controller and the OCAPI-managed storage/enclosure device can present any certificate, intercept the session, capture the credentials, and tamper with responses.

A flaw was found in the ipa_getkeytab module of the community.general Ansible collection. The module's bind_pw parameter, used to supply the LDAP simple-bind password when retrieving a Kerberos keytab, is not declared with no_log, unlike the sibling password parameter in the same module. As a consequence, the supplied IPA/LDAP bind password is recorded in cleartext in the managed host's system journal/syslog (the module's "Invoked with" record), is included in the module's return values and verbose (-v) output, and is displayed in Automation Controller / AWX job output. The password is additionally passed on the command line to the ipa-getkeytab helper (as --bindpw <value>), exposing it in the process list to local users while the command runs. An attacker able to read these logs, job output, or the process table can obtain the directory bind credential, potentially compromising the accounts and objects that credential can access.

A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in a Denial of Service (DoS) for the affected system.

A flaw was found in ansible-collection-community-general. This vulnerability allows for information exposure (IE) of sensitive credentials, specifically plaintext passwords, via verbose output when running Ansible with debug modes. Attackers with access to logs could retrieve these secrets and potentially compromise Keycloak accounts or administrative access.
