GHSA-6R93-82VQ-9W4W
Vulnerability from github – Published: 2022-05-24 17:43 – Updated: 2025-10-22 00:32An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to gain unauthorized access and complete the authentication process. Subsequently, the client can execute data management protocol commands on the authenticated connection. The attacker could use one of these commands to execute an arbitrary command on the system using system privileges.

GHSA-6RHQ-RX45-FHHP
Vulnerability from github – Published: 2026-07-10 21:32 – Updated: 2026-07-10 21:32The miniOrange Social Login and Register (Discord, Google, Twitter, LinkedIn) plugin for WordPress is vulnerable to authentication bypass leading to account takeover in versions up to and including 7.7.0. This is due to the Profile Completion flow accepting an arbitrary email address via the 'email_field' POST parameter without verifying that the email belongs to the identity returned by the OAuth provider, combined with send_otp_token() returning the SHA-512(customer_key || otp) transaction hash to the client where the OTP space is only 99,000 values (wp_rand(1000, 99999)) and the customer_key is a static option (empty on unregistered installs). This makes it possible for unauthenticated attackers to trigger an OTP email to an arbitrary admin's address, crack the OTP offline from the leaked hash in under a second, and submit the cracked OTP to mo_openid_social_login_validate_otp(), which logs the attacker in as the user whose email was supplied — granting full administrator access.

The vulnerability is due to an insecure default configuration of the Apache ZooKeeper service used by the affected software. An attacker could exploit this vulnerability by accessing the affected device through the orchestrator network. An exploit could allow the attacker to gain access to ZooKeeper data nodes (znodes) and influence the behavior of the system's high-availability feature. This vulnerability affects all releases of Cisco Ultra Services Framework UAS prior to Releases 5.0.3 and 5.1. Cisco Bug IDs: CSCvd29395.

Mitigation
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
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-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
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.
