CVE-2020-36724 (GCVE-0-2020-36724)

Vulnerability from cvelistv5 – Published: 2023-06-07 01:51 – Updated: 2026-04-08 17:19

Title
Wordable <= 3.1.1 - Authentication Bypass
Summary
The Wordable plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 3.1.1. This is due to the use of a user supplied hashing algorithm passed to the hash_hmac() function and the use of a loose comparison on the hash which allows an attacker to trick the function into thinking it has a valid hash. This makes it possible for unauthenticated attackers to gain administrator privileges.

Title
MStore API <= 2.1.5 - Authentication Bypass
Summary
The MStore API plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.1.5. This is due to unrestricted access to the 'register' and 'update_user_profile' routes. This makes it possible for unauthenticated attackers to create new administrator accounts, delete existing administrator accounts, or escalate privileges on any account.

CVE-2020-27866 (GCVE-0-2020-27866)

Vulnerability from cvelistv5 – Published: 2021-02-11 23:35 – Updated: 2024-08-04 16:25
VLAI
Summary
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6020, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, R7450, JNR3210, WNR2020, Nighthawk AC2100, and Nighthawk AC2400 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the mini_httpd service, which listens on TCP port 80 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-11355.

Mitigation
Architecture and Design

Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.

CAPEC-127: Directory Indexing

An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.

CAPEC-665: Exploitation of Thunderbolt Protection Flaws

An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
