Istio versions 1.2.10 (End of Life) and prior, 1.3 through 1.3.7, and 1.4 through 1.4.3 allows authentication bypass. The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting a valid JWT token. For example, an attacker can add a ? or # character to a URI that would otherwise satisfy an exact-path match.

The openshift-origin-broker in Red Hat OpenShift Enterprise 2.0.5, 1.2.7, and earlier does not properly handle authentication requests from the remote-user auth plugin, which allows remote attackers to bypass authentication and impersonate arbitrary users via the X-Remote-User header in a request to a passthrough trigger.

IBM Cloud Pak for Security (CP4S) 1.7.0.0, 1.7.1.0, 1.7.2.0, and 1.8.0.0 could allow an attacker to perform unauthorized actions due to improper or missing authentication controls. IBM X-Force ID: 199282.

The GateIn Portal export/import gadget in JBoss Enterprise Portal Platform 5.2.2 does not properly check authentication when importing Zip files, which allows remote attackers to modify site contents, remove the site, or alter the access controls for portlets.

The client in OpenSSH before 7.2 mishandles failed cookie generation for untrusted X11 forwarding and relies on the local X11 server for access-control decisions, which allows remote X11 clients to trigger a fallback and obtain trusted X11 forwarding privileges by leveraging configuration issues on this X11 server, as demonstrated by lack of the SECURITY extension on this X11 server.

A vulnerability was found in Keycloak 7.x where the user federation LDAP bind type is none (LDAP anonymous bind), any password, invalid or valid will be accepted.

A vulnerability was found in keycloak 7.x, when keycloak is configured with LDAP user federation and StartTLS is used instead of SSL/TLS from the LDAP server (ldaps), in this case user authentication succeeds even if invalid password has entered.

An authentication bypass vulnerability has been identified in Pulpcore when deployed with Gunicorn versions prior to 22.0, due to the puppet-pulpcore configuration. This issue arises from Apache's mod_proxy not properly unsetting headers because of restrictions on underscores in HTTP headers, allowing authentication through a malformed header. This flaw impacts all active Satellite deployments (6.13, 6.14 and 6.15) which are using Pulpcore version 3.0+ and could potentially enable unauthorized users to gain administrative access.

FreeRADIUS before 3.0.19 does not prevent use of reflection for authentication spoofing, aka a "Dragonblood" issue, a similar issue to CVE-2019-9497.

transport.py in the SSH server implementation of Paramiko before 1.17.6, 1.18.x before 1.18.5, 2.0.x before 2.0.8, 2.1.x before 2.1.5, 2.2.x before 2.2.3, 2.3.x before 2.3.2, and 2.4.x before 2.4.1 does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step.

An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.

openshift-ansible before versions 3.9.23, 3.7.46 deploys a misconfigured etcd file that causes the SSL client certificate authentication to be disabled. Quotations around the values of ETCD_CLIENT_CERT_AUTH and ETCD_PEER_CLIENT_CERT_AUTH in etcd.conf result in etcd being configured to allow remote users to connect without any authentication if they can access the etcd server bound to the network on the master nodes. An attacker could use this flaw to read and modify all the data about the Openshift cluster in the etcd datastore, potentially adding another compute node, or bringing down the entire cluster.

An issue was discovered in WildFly 10.1.2.Final. In the case of a default installation without a security realm reference, an attacker can successfully access the server without authentication. NOTE: the Security Realms documentation in the product's Admin Guide indicates that "without a security realm reference" implies "effectively unsecured." The vendor explicitly supports these unsecured configurations because they have valid use cases during development

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.

A flaw was found in Red Hat DataGrid 8.x (8.0.0, 8.0.1, 8.1.0 and 8.1.1) and Infinispan (10.0.0 through 12.0.0). An attacker could bypass authentication on all REST endpoints when DIGEST is used as the authentication method. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

The admin terminal in Hawt.io does not require authentication, which allows remote attackers to execute arbitrary commands via the k parameter.

curl, as shipped in Red Hat Enterprise Linux 6 before version 7.19.7-53, did not correctly backport the fix for CVE-2015-3148 because it did not reflect the fact that the HAVE_GSSAPI define was meanwhile substituted by USE_HTTP_NEGOTIATE. This issue was introduced in RHEL 6.7 and affects RHEL 6 curl only.

The version of Sendmail 8.13.1-2 on Red Hat Enterprise Linux 4 Update 4 and earlier does not allow the administrator to disable SSLv2 encryption, which could cause less secure channels to be used than desired.

Unspecified vulnerability in Plone 2.5 through 4.0, as used in Conga, luci, and possibly other products, allows remote attackers to obtain administrative access, read or create arbitrary content, and change the site skin via unknown vectors.

slapd (aka ns-slapd) in 389 Directory Server 1.2.7.5 (aka Red Hat Directory Server 8.2.x or dirsrv) does not properly handle simple paged result searches, which allows remote attackers to cause a denial of service (daemon crash) or possibly have unspecified other impact via multiple search requests.

Buffer overflow in mhshow in the Linux nmh package allows remote attackers to execute commands via malformed MIME headers in an email message.

Heap-based buffer overflow in the unhtmlify function in foomatic-rip in foomatic-filters before 4.0.6 allows remote attackers to cause a denial of service (memory corruption and crash) or possibly execute arbitrary code via a long job title.

The _httpsrequest function in Snoopy allows remote attackers to execute arbitrary commands. NOTE: this issue exists dues to an incomplete fix for CVE-2008-4796.

Double free vulnerability in libxml2 2.7.8 and other versions, as used in Google Chrome before 8.0.552.215 and other products, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling.

The serialization implementation in JBoss Drools in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3 before 4.3.0.CP09 and JBoss Enterprise SOA Platform 4.2 and 4.3 supports the embedding of class files, which allows remote attackers to execute arbitrary code via a crafted static initializer.

The Gfx::getPos function in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, CUPS, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) via unknown vectors that trigger an uninitialized pointer dereference.

A missing patch for a stack-based buffer overflow in findTable() was found in Red Hat version of liblouis before 2.5.4. An attacker could cause a denial of service condition or potentially even arbitrary code execution.

A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.

A use-after-free vulnerability occurs during transaction processing in the editor during design mode interactions. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

A file inclusion vulnerability was found in the AJP connector enabled with a default AJP configuration port of 8009 in Undertow version 2.0.29.Final and before and was fixed in 2.0.30.Final. A remote, unauthenticated attacker could exploit this vulnerability to read web application files from a vulnerable server. In instances where the vulnerable server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types and trigger this vulnerability to gain remote code execution.

A use-after-free vulnerability occurs when redirecting focus handling which results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

An insufficient JWT validation vulnerability was found in Kiali versions 0.4.0 to 1.15.0 and was fixed in Kiali version 1.15.1, wherein a remote attacker could abuse this flaw by stealing a valid JWT cookie and using that to spoof a user session, possibly gaining privileges to view and alter the Istio configuration.

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.

A hard-coded cryptographic key vulnerability in the default configuration file was found in Kiali, all versions prior to 1.15.1. A remote attacker could abuse this flaw by creating their own JWT signed tokens and bypass Kiali authentication mechanisms, possibly gaining privileges to view and alter the Istio configuration.

Certain Fedora build scripts for nfs-utils before 1.1.2-9.fc9 on Fedora 9, and before 1.1.4-6.fc10 on Fedora 10, omit TCP Wrapper support, which might allow remote attackers to bypass intended access restrictions, possibly a related issue to CVE-2008-1376.

Double free vulnerabilities in the error handling code for ASN.1 decoders in the (1) Key Distribution Center (KDC) library and (2) client library for MIT Kerberos 5 (krb5) 1.3.4 and earlier may allow remote attackers to execute arbitrary code.

Unknown vulnerability in redhat-config-nfs before 1.0.13, when shares are exported to multiple hosts, can produce incorrect permissions and prevent the all_squash option from being applied.

Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.

Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response.

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously.

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request.

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

The Zephyr parser in tcpdump before 4.9.2 has a buffer over-read in print-zephyr.c, several functions.

The IEEE 802.11 parser in tcpdump before 4.9.2 has a buffer over-read in print-802_11.c:parse_elements().

The ISAKMP parser in tcpdump before 4.9.2 has a buffer over-read in print-isakmp.c:isakmp_rfc3948_print().

The DECnet parser in tcpdump before 4.9.2 has a buffer over-read in print-decnet.c:decnet_print().

up2date 3.0.7 and 3.1.23 does not properly verify RPM GPG signatures, which could allow remote attackers to cause unsigned packages to be installed from the Red Hat Network, if that network is compromised.
