Description

This security bulletin contains information about 2 vulnerabilities.


1) Use of insufficiently random values (CVE-ID: CVE-2020-5408)

CWE-ID: CWE-330 - Use of Insufficiently Random Values

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the affected software uses a fixed null initialization vector with CBC Mode in the implementation of the queryable text encryptor. A remote authenticated attacker can derive the unencrypted values using a dictionary attack.


2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2020-5407)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to a signature wrapping issue during SAML response validation when using the "spring-security-saml2-service-provider" component. A remote authenticated attacker can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.
