Details

The Velociraptor gRPC API has a VFSGetBuffer endpoint which allows reading files from the datastore. To prevent users from reading sensitive files or accessing other orgs, the requested path is prefix checked against a list of denied prefixes. This prefix check can be bypassed allowing a user to access usually denied files. If the user has read permission in the ROOT org, this allows access to other orgs, in which the user may not have permission.

Vulnerability from github – Published: 2025-03-19 12:30 – Updated: 2025-03-19 12:30
VLAI
Details

The Service Finder Bookings plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 5.0. This is due to the plugin not properly validating a user's identity prior to (1) performing a post-booking auto-login or (2) updating their profile details (e.g. password). This makes it possible for unauthenticated attackers to (1) login as an arbitrary user if their email address is known or (2) change an arbitrary user's password, including administrators, and leverage that to gain access to their account.

A vulnerability in the social login configuration option for the guest users of Cisco Business Wireless Access Points (APs) could allow an unauthenticated, adjacent attacker to bypass social login authentication. This vulnerability is due to a logic error with the social login implementation. An attacker could exploit this vulnerability by attempting to authenticate to an affected device. A successful exploit could allow the attacker to access the Guest Portal without authentication.

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.
