CVE-2019-14887 vulnerability in Red Hat Products
Published on March 16, 2020
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.
Weakness Type
What is an Algorithm Downgrade Vulnerability?
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. When a security mechanism can be forced to downgrade to use a less secure algorithm, this can make it easier for attackers to compromise the software by exploiting weaker algorithm. The victim might not be aware that the less secure algorithm is being used. For example, if an attacker can force a communications channel to use cleartext instead of strongly-encrypted data, then the attacker could read the channel by sniffing, instead of going through extra effort of trying to decrypt the data using brute force techniques.
CVE-2019-14887 has been classified to as an Algorithm Downgrade vulnerability or weakness.
