CVE-2013-1840

Openstack glance: swift: s3: openstack glance: information disclosure of backend credentials via cached image request

A flaw was found in OpenStack Glance. Remote authenticated users can exploit this vulnerability by requesting a cached image when the single-tenant Swift or S3 store is in use. This action causes the system to report the location field, which can lead to the disclosure of the operator's backend credentials.

Puppetlabs-cinder: packstack: openstack: puppetlabs-cinder: information disclosure of openstack administrative passwords due to world-readable configuration files.

A flaw was found in the `puppetlabs-cinder` module, as used in PackStack. This vulnerability is due to incorrect file permissions, specifically world-readable permissions, on the `cinder.conf` and `api-paste.ini` configuration files. A local user can exploit this by reading these files, which leads to the disclosure of OpenStack administrative passwords. This information disclosure could allow unauthorized access to sensitive OpenStack resources.

Openstack keystone: openstack keystone: authorization bypass via improper ec2 token handling

A flaw was found in OpenStack Keystone. This vulnerability allows remote authenticated users to bypass intended authorization restrictions. This occurs because OpenStack Keystone does not properly handle EC2 (Elastic Compute Cloud) tokens when a user's role has been removed from a tenant. An attacker can leverage a token associated with a removed user role to gain unauthorized access.

Ansible-operator-plugins: ansible operator plugins: arbitrary code execution via jinja2 template injection

A flaw was found in Ansible Operator Plugins. A low-privileged Kubernetes user can exploit a Jinja2 template injection vulnerability by crafting malicious custom resource (CR) specification values. These values are processed by Ansible without proper sanitization, allowing embedded Jinja2 expressions to be executed within the operator pod. This can lead to arbitrary code execution and privilege escalation, granting the attacker control over the operator's service account with cluster-wide permissions.

Openstack-network-exporter: http.server has no readheadertimeout / readtimeout (slowloris)

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.

Openstack-network-exporter: basic-auth uses plaintext password storage and non-constant-time comparison

A flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security (TLS), the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open vSwitch (OVS) and Open Virtual Network (OVN) dataplane metrics without credentials. Consequently, an attacker can enumerate bridge names, port counters, OVN controller state, and host topology, leading to information disclosure.

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.

Community.general: community.general: memcached cache plugin deserializes untrusted pickle data from memcached, enabling cache-poisoning remote code execution on the ansible controller

A flaw was found in the memcached cache plugin of the community.general Ansible collection. Although its documentation states that records are stored in JSON format, the plugin performs no explicit serialization and relies on python-memcached, which pickles values on write and unpickles them on read. Because memcached is unauthenticated and cache keys are predictable, an attacker able to reach a network-exposed or shared memcached instance can write a crafted pickle payload that is deserialized and executed on the Ansible controller when the poisoned fact cache is next read, leading to remote code execution.

There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.

Ansible-collection-community-general: community.general: ipa_getkeytab does not set no_log on the bind_pw parameter, disclosing the ipa bind password in logs and process listings

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 openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.
