Vulnerability from github – Published: 2024-03-14 03:31 – Updated: 2025-05-01 00:32
VLAI
Details

Insecure key exchange between Delinea PAM Secret Server 11.4 and the Distributed Engine 8.4.3 allows a PAM administrator to obtain the Symmetric Key (used to encrypt RabbitMQ messages) via crafted payloads to the /pre-authenticate, /authenticate, and /execute-and-respond REST API endpoints. This makes it possible for a PAM administrator to impersonate the Engine and exfiltrate sensitive information from the messages published in the RabbitMQ exchanges, without being audited in the application.

Vulnerability from github – Published: 2022-12-23 15:30 – Updated: 2024-03-27 15:30
VLAI
Details

A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E) .. Then in a subsequent request, it does not detect the HSTS state and makes a clear text transfer. Because it would store the info IDN encoded but look for it IDN decoded.

easy_install in setuptools before 0.7 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to the default use of the product.

Vulnerability from github – Published: 2021-12-17 00:00 – Updated: 2022-03-30 00:02
VLAI
Details

The ksmbd server through 3.4.2, as used in the Linux kernel through 5.15.8, sometimes communicates in cleartext even though encryption has been enabled. This occurs because it sets the SMB2_GLOBAL_CAP_ENCRYPTION flag when using the SMB 3.1.1 protocol, which is a violation of the SMB protocol specification. When Windows 10 detects this protocol violation, it disables encryption.

Details

VERSION NOT SUPPORTED WHEN ASSIGNED A vulnerability could cause certain data to be visible on the network when the 'password' feature is enabled. This vulnerability was discovered in and remediated in versions v4.9.1 and v4.10.1 on May 30, 2013. The 'password' feature is an additional optional check performed by TS1131 that it is connected to a specific controller. This data is sent as clear text and is visible on the network. This feature is not present in TriStation 1131 versions v4.9.1 and v4.10.1 through current. Therefore, the vulnerability is not present in these versions.

Mitigation
Architecture and Design

Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.

Mitigation
Implementation

When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.

Mitigation
Implementation

When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.

Mitigation
Testing

Use tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session. These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.

Mitigation
Operation

Configure servers to use encrypted channels for communication, which may include SSL or other secure protocols.

CAPEC-102: Session Sidejacking

Session sidejacking takes advantage of an unencrypted communication channel between a victim and target system. The attacker sniffs traffic on a network looking for session tokens in unencrypted traffic. Once a session token is captured, the attacker performs malicious actions by using the stolen token with the targeted application to impersonate the victim. This attack is a specific method of session hijacking, which is exploiting a valid session token to gain unauthorized access to a target system or information. Other methods to perform a session hijacking are session fixation, cross-site scripting, or compromising a user or server machine and stealing the session token.

CAPEC-117: Interception

An adversary monitors data streams to or from the target for information gathering purposes. This attack may be undertaken to solely gather sensitive information or to support a further attack against the target. This attack pattern can involve sniffing network traffic as well as other types of data streams (e.g. radio). The adversary can attempt to initiate the establishment of a data stream or passively observe the communications as they unfold. In all variants of this attack, the adversary is not the intended recipient of the data stream. In contrast to other means of gathering information (e.g., targeting data leaks), the adversary must actively position themself so as to observe explicit data channels (e.g. network traffic) and read the content. However, this attack differs from a Adversary-In-the-Middle (CAPEC-94) attack, as the adversary does not alter the content of the communications nor forward data to the intended recipient.

CAPEC-383: Harvesting Information via API Event Monitoring

An adversary hosts an event within an application framework and then monitors the data exchanged during the course of the event for the purpose of harvesting any important data leaked during the transactions. One example could be harvesting lists of usernames or userIDs for the purpose of sending spam messages to those users. One example of this type of attack involves the adversary creating an event within the sub-application. Assume the adversary hosts a "virtual sale" of rare items. As other users enter the event, the attacker records via AiTM (CAPEC-94) proxy the user_ids and usernames of everyone who attends. The adversary would then be able to spam those users within the application using an automated script.

CAPEC-477: Signature Spoofing by Mixing Signed and Unsigned Content

An attacker exploits the underlying complexity of a data structure that allows for both signed and unsigned content, to cause unsigned data to be processed as though it were signed data.

CAPEC-65: Sniff Application Code

An adversary passively sniffs network communications and captures application code bound for an authorized client. Once obtained, they can use it as-is, or through reverse-engineering glean sensitive information or exploit the trust relationship between the client and server. Such code may belong to a dynamic update to the client, a patch being applied to a client component or any such interaction where the client is authorized to communicate with the server.
