Vulnerability from github – Published: 2022-07-28 00:00 – Updated: 2022-08-03 00:00

Details

An authentication bypass vulnerability in Skyhigh SWG in main releases 10.x prior to 10.2.12, 9.x prior to 9.2.23, 8.x prior to 8.2.28, and controlled release 11.x prior to 11.2.1 allows a remote attacker to bypass authentication into the administration User Interface. This is possible because of SWG incorrectly whitelisting authentication bypass methods and using a weak crypto password. This can lead to the attacker logging into the SWG admin interface, without valid credentials, as the super user with complete control over the SWG.

Vulnerability from github – Published: 2026-07-15 18:31 – Updated: 2026-07-21 06:31
VLAI
Details

A flaw was found in the AAP Gateway Envoy proxy configuration. The non-mTLS route to EDA event streams does not remove the Subject HTTP header from client requests, despite the source code defining requestHeadersToRemove for this header. An unauthenticated remote attacker can inject a spoofed Subject header matching a legitimate client certificate DN to bypass mTLS authentication and inject arbitrary events into protected EDA event streams.

SAP NetWeaver Process Integration (Adapter Engine), fixed in versions 7.10 to 7.11, 7.30, 7.31, 7.40, 7.50; is vulnerable to Digital Signature Spoofing. It is possible to spoof XML signatures and send arbitrary requests to the server via PI Axis adapter. These requests will be accepted by the PI Axis adapter even if the payload has been altered, especially when the signed element is the body of the xml document.

Summary
omniauth-apple allows attacker to fake their email address during authentication
Details

Impact

This vulnerability impacts applications using the omniauth-apple strategy of OmniAuth and using the info.email field of OmniAuth's Auth Hash Schema for any kind of identification. The value of this field may be set to any value of the attacker's choice including email addresses of other users.

For example, an application using omniauth-apple with the following code will be impacted:

def omniauth_callback
    auth_hash = request.env['omniauth.auth']
    @authenticated_user = User.find_by(email: auth_hash.info.email)
end

Applications not using info.email for identification but are instead using the uid field are not impacted in the same manner. Note, these applications may still be negatively affected if the value of info.email is being used for other purposes.

Patches

Applications using affected versions of omniauth-apple are advised to upgrade to omniauth-apple version 1.0.1 or later.

Workarounds

If unable to upgrade to a patched version, monkey patching OmniAuth::Strategies::Apple#email as follows is advised as a workaround:

module OmniAuth
  module Strategies
    class Apple
      def email
        id_info['email']
      end
    end
  end
end

Vulnerability from github – Published: 2022-05-24 17:29 – Updated: 2026-07-05 00:31
VLAI
Details

The custom GINA/CP module in ANIXIS Password Reset Client before version 3.22 allows remote attackers to execute code and escalate privileges via spoofing. When the client is configured to use HTTP, it does not authenticate the intended server before opening a browser window. An unauthenticated attacker capable of conducting a spoofing attack can redirect the browser to gain execution in the context of the WinLogon.exe process. If Network Level Authentication is not enforced, the vulnerability can be exploited via RDP.

GHSA-4G73-3MXF-J47W

Vulnerability from github – Published: 2022-01-14 00:02 – Updated: 2025-10-22 00:32
VLAI
Details

In the case of instances where the SAML SSO authentication is enabled (non-default), session data can be modified by a malicious actor, because a user login stored in the session was not verified. Malicious unauthenticated actor may exploit this issue to escalate privileges and gain admin access to Zabbix Frontend. To perform the attack, SAML authentication is required to be enabled and the actor has to know the username of Zabbix user (or use the guest account, which is disabled by default).

No mitigation information available for this CWE.

CAPEC-21: Exploitation of Trusted Identifiers

An adversary guesses, obtains, or "rides" a trusted identifier (e.g. session ID, resource ID, cookie, etc.) to perform authorized actions under the guise of an authenticated user or service.

CAPEC-22: Exploiting Trust in Client

An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.

CAPEC-459: Creating a Rogue Certification Authority Certificate

An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.

CAPEC-461: Web Services API Signature Forgery Leveraging Hash Function Extension Weakness

An adversary utilizes a hash function extension/padding weakness, to modify the parameters passed to the web service requesting authentication by generating their own call in order to generate a legitimate signature hash (as described in the notes), without knowledge of the secret token sometimes provided by the web service.

CAPEC-473: Signature Spoof

An attacker generates a message or datablock that causes the recipient to believe that the message or datablock was generated and cryptographically signed by an authoritative or reputable source, misleading a victim or victim operating system into performing malicious actions.

CAPEC-476: Signature Spoofing by Misrepresentation

An attacker exploits a weakness in the parsing or display code of the recipient software to generate a data blob containing a supposedly valid signature, but the signer's identity is falsely represented, which can lead to the attacker manipulating the recipient software or its victim user to perform compromising actions.

CAPEC-59: Session Credential Falsification through Prediction

This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

CAPEC-60: Reusing Session IDs (aka Session Replay)

This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.

CAPEC-667: Bluetooth Impersonation AttackS (BIAS)

An adversary disguises the MAC address of their Bluetooth enabled device to one for which there exists an active and trusted connection and authenticates successfully. The adversary can then perform malicious actions on the target Bluetooth device depending on the target’s capabilities.

CAPEC-94: Adversary in the Middle (AiTM)

An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
