Common Weakness Enumeration

CWE-757

Allowed

Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

Abstraction: Base · Status: Incomplete

A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.

60 vulnerabilities reference this CWE, most recent first.

CVE-2022-23000 (GCVE-0-2022-23000)

Vulnerability from cvelistv5 – Published: 2022-07-25 18:46 – Updated: 2024-08-03 03:28
VLAI
Title
Weak Default SSL use in Port Forwarding Service
Summary
The Western Digital My Cloud Web App [https://os5.mycloud.com/] uses a weak SSLContext when attempting to configure port forwarding rules. This was enabled to maintain compatibility with old or outdated home routers. By using an "SSL" context instead of "TLS" or specifying stronger validation, deprecated or insecure protocols are permitted. As a result, a local user with no privileges can exploit this vulnerability and jeopardize the integrity, confidentiality and authenticity of information transmitted. The scope of impact cannot extend to other components and no user input is required to exploit this vulnerability.

CVE-2020-10135 (GCVE-0-2020-10135)

Vulnerability from cvelistv5 – Published: 2020-05-19 15:50 – Updated: 2024-09-17 02:57
VLAI
Title
Bluetooth devices supporting BR/EDR v5.2 and earlier are vulnerable to impersonation attacks
Summary
Legacy pairing and secure-connections pairing authentication in Bluetooth BR/EDR Core Specification v5.2 and earlier may allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. An unauthenticated, adjacent attacker could impersonate a Bluetooth BR/EDR master or slave to pair with a previously paired remote device to successfully complete the authentication procedure without knowing the link key.
CWE
  • CWE-757 - Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

CVE-2019-14887 (GCVE-0-2019-14887)

Vulnerability from cvelistv5 – Published: 2020-03-16 14:48 – Updated: 2024-08-05 00:26
VLAI
Summary
A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption. This could lead to a leak of the data being passed over the network. Wildfly version 7.2.0.GA, 7.2.3.GA and 7.2.5.CR2 are believed to be vulnerable.

CAPEC-220: Client-Server Protocol Manipulation

An adversary takes advantage of weaknesses in the protocol by which a client and server are communicating to perform unexpected actions. Communication protocols are necessary to transfer messages between client and server applications. Moreover, different protocols may be used for different types of interactions.

CAPEC-606: Weakening of Cellular Encryption

An attacker, with control of a Cellular Rogue Base Station or through cooperation with a Malicious Mobile Network Operator can force the mobile device (e.g., the retransmission device) to use no encryption (A5/0 mode) or to use easily breakable encryption (A5/1 or A5/2 mode).

CAPEC-620: Drop Encryption Level

An attacker forces the encryption level to be lowered, thus enabling a successful attack against the encrypted data.
