TP-Link Omada SDN Software Controller before 5.0.15 does not check if the authentication method specified in a connection request is allowed. An attacker can bypass the captive portal authentication process by using the downgraded "no authentication" method, and access the protected network. For example, the attacker can simply set window.authType=0 in client-side JavaScript.

TP-Link C2 and C20i devices through firmware 0.9.1 4.2 v0032.0 Build 160706 Rel.37961n have too permissive iptables rules, e.g., SNMP is not blocked on any interface.

This vulnerability allows network-adjacent attackers to escalate privileges on affected installations of TP-Link TL-WA855RE Firmware Ver: 855rev4-up-ver1-0-1-P1[20191213-rel60361] Wi-Fi extenders. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the first-time setup process. The issue results from the lack of proper validation on first-time setup requests. An attacker can leverage this vulnerability to reset the password for the Admin account and execute code in the context of the device. Was ZDI-CAN-10003.

This vulnerability allows remote attackers to bypass authentication on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SSH port forwarding requests during initial setup. The issue results from the lack of proper authentication prior to establishing SSH port forwarding rules. An attacker can leverage this vulnerability to escalate privileges to resources normally protected from the WAN interface. Was ZDI-CAN-9664.

When adding Referer: http://tplinkwifi.net to the the request, it will be recognized as passing the authentication. NOTE: this is disputed by the Supplier because the response to the API call is only "non-sensitive UI initialization variables."

TP-Link SG105PE firmware prior to 'TL-SG105PE(UN) 1.0_1.0.0 Build 20221208' contains an authentication bypass vulnerability.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 4.10.11 and 5.2.2, the certificate in the Parse Server Apple Game Center auth adapter not validated. As a result, authentication could potentially be bypassed by making a fake certificate accessible via certain Apple domains and providing the URL to that certificate in an authData object. Versions 4.0.11 and 5.2.2 prevent this by introducing a new `rootCertificateUrl` property to the Parse Server Apple Game Center auth adapter which takes the URL to the root certificate of Apple's Game Center authentication certificate. If no value is set, the `rootCertificateUrl` property defaults to the URL of the current root certificate as of May 27, 2022. Keep in mind that the root certificate can change at any time and that it is the developer's responsibility to keep the root certificate URL up-to-date when using the Parse Server Apple Game Center auth adapter. There are no known workarounds for this issue.

RSA Adaptive Authentication (On-Premise) 6.0.2.1 through 7.1 P3, when using device binding in a Challenge SOAP call or using the RSA Adaptive Authentication Integration Adapters with Out-of-Band Phone (Authentify) functionality, conducts permanent device binding even when authentication fails, which allows remote attackers to bypass authentication.

Apache WSS4J before 1.6.17 and 2.x before 2.0.2, as used in Apache CXF 2.7.x before 2.7.13 and 3.0.x before 3.0.2, when using TransportBinding, does not properly enforce the SAML SubjectConfirmation method security semantics, which allows remote attackers to conduct spoofing attacks via unspecified vectors.

The login form in the Web component in IBM Rational ClearQuest 7.1 before 7.1.2.15, 8.0.0 before 8.0.0.12, and 8.0.1 before 8.0.1.5 does not insert a delay after a failed authentication attempt, which makes it easier for remote attackers to obtain access via a brute-force attack.

A vulnerability has been identified in SICAM T (All versions < V3.0). Affected devices do not restrict unauthenticated access to certain pages of the web interface. This could allow an attacker to delete log files without authentication.

Mozilla Firefox before 2.0.0.13 and SeaMonkey before 1.1.9, when generating the HTTP Referer header, does not list the entire URL when it contains Basic Authentication credentials without a username, which makes it easier for remote attackers to bypass application protection mechanisms that rely on Referer headers, such as with some Cross-Site Request Forgery (CSRF) mechanisms.

A vulnerability has been identified in SICAM GridEdge (Classic) (All versions < V2.6.6). The affected application does not require authenticated access for privileged functions. This could allow an unauthenticated attacker to change data of a user, such as credentials, in case that user's id is known.

In IQrouter through 3.3.1, the Lua function diag_set_password in the web-panel allows remote attackers to change the root password arbitrarily. Note: The vendor claims that this vulnerability can only occur on a brand-new network that, after initiating the forced initial configuration (which has a required step for setting a secure password on the system), makes this CVE invalid. This vulnerability is “true for any unconfigured release of OpenWRT, and true of many other new Linux distros prior to being configured for the first time”

Flat PHP Board 1.2 and earlier allows remote attackers to bypass authentication and obtain limited access to an arbitrary user account via the fpb_username cookie.

An issue was discovered on Samsung mobile devices with O(8.x) and P(9.0) software. Attackers can change the USB configuration without authentication. The Samsung ID is SVE-2018-13300 (September 2019).

A vulnerability in the protocol detection component of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to improper detection of the initial use of a protocol on a nonstandard port. An attacker could exploit this vulnerability by sending traffic on a nonstandard port for the protocol in use through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious requests to protected systems that would otherwise be blocked. Once the initial protocol flow on the nonstandard port is detected, future flows on the nonstandard port will be successfully detected and handled as configured by the applied policy.

An issue was discovered on Samsung mobile devices with P(9.0) software. The Settings application allows unauthenticated changes. The Samsung IDs are SVE-2019-13814, SVE-2019-13815 (March 2019).

Session fixation vulnerability in eXV2 CMS 2.0.4.3 and earlier allows remote attackers to hijack web sessions by setting the PHPSESSID cookie.

An issue was discovered in Serpico (aka SimplE RePort wrIting and CollaboratiOn tool) 1.3.0. An admin can change their password without providing the current password, by using interfaces outside the Change Password screen. Thus, requiring the admin to enter an Old Password value on the Change Password screen does not enhance security. This is problematic in conjunction with XSS.

RubyGem omniauth-facebook has an access token security vulnerability

The WordPress plugin, Email Subscribers & Newsletters, before 4.2.3 had a flaw that allowed for unauthenticated option creation. In order to exploit this vulnerability, an attacker would need to send a /wp-admin/admin-post.php?es_skip=1&option_name= request.
