Summary
Statamic allows Authenticated Control Panel users to escalate privileges via elevated session bypass
Details

Impact

Authenticated Control Panel users may under certain conditions obtain elevated privileges without completing the intended verification step. This can allow access to sensitive operations and, depending on the user’s existing permissions, may lead to privilege escalation.

Patches

This has been fixed in 6.4.0.

Summary
TYPO3 Security Misconfiguration for Backend User Accounts
Details

When using the TYPO3 backend in order to create new backend user accounts, database records containing insecure or empty credentials might be persisted. When the type of user account is changed - which might be entity type or the admin flag for backend users - the backend form is reloaded in order to reflect changed configuration possibilities. However, this leads to persisting the current state as well, which can result into some of the following:

  • account contains empty login credentials (username and/or password)
  • account is incomplete and contains weak credentials (username and/or password)

Albeit the functionality provided by the TYPO3 core cannot be used either with empty usernames or empty passwords, it still can be a severe vulnerability to custom authentication service implementations.

This weakness cannot be directly exploited and requires interaction on purpose by some backend user having according privileges.

However,  this leads to persisting the current state as well, which can result into some of the following:\n\n- account contains empty login credentials (username and/or password)\n- account is incomplete and contains weak credentials (username and/or password)\n\nAlbeit the functionality provided by the TYPO3 core cannot be used either with empty usernames or empty passwords, it still can be a severe vulnerability to custom authentication service implementations.\n\nThis weakness cannot be directly exploited and requires interaction on purpose by some backend user having according privileges.\n\n",

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.
