CVE-2020-12145 (GCVE-0-2020-12145)

Vulnerability from cvelistv5 – Published: 2020-11-05 18:48 – Updated: 2024-09-16 17:07
VLAI
Title
Silver Peak Unity OrchestratorTM authentication can be subverted through manipulation of HTTP headers.
Summary
Silver Peak Unity Orchestrator versions prior to 8.9.11+, 8.10.11+, or 9.0.1+ uses HTTP headers to authenticate REST API calls from localhost. This makes it possible to log in to Orchestrator by introducing an HTTP HOST header set to 127.0.0.1 or localhost. Orchestrator instances that are hosted by customers –on-premise or in a public cloud provider –are affected by this vulnerability.
Severity

This vulnerability allows remote attackers to bypass authentication on affected installations of C-MORE HMI EA9 Firmware version 6.52 touch screen panels. Authentication is not required to exploit this vulnerability. The specific flaw exists within the authentication mechanism. The issue is due to insufficient authentication on post-authentication requests. An attacker can leverage this vulnerability to escalate privileges to resources normally protected from unauthenticated users. Was ZDI-CAN-10182.

CVE-2020-10916 (GCVE-0-2020-10916)

Vulnerability from cvelistv5 – Published: 2020-05-07 22:20 – Updated: 2024-08-04 11:14
VLAI
Summary
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.

CVE-2020-10888 (GCVE-0-2020-10888)

Vulnerability from cvelistv5 – Published: 2020-03-25 19:15 – Updated: 2024-08-04 11:14
VLAI
Summary
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.

CVE-2020-10709 (GCVE-0-2020-10709)

Vulnerability from cvelistv5 – Published: 2021-05-27 18:46 – Updated: 2024-08-04 11:06
VLAI
Summary
A security flaw was found in Ansible Tower when requesting an OAuth2 token with an OAuth2 application. Ansible Tower uses the token to provide authentication. This flaw allows an attacker to obtain a refresh token that does not expire. The original token granted to the user still has access to Ansible Tower, which allows any user that can gain access to the token to be fully authenticated to Ansible Tower. This flaw affects Ansible Tower versions before 3.6.4 and Ansible Tower versions before 3.5.6.

Mitigation
Architecture and Design

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.
