Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) LDAP injection (CVE-ID: CVE-2023-33201)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to improper input validation in applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability. A remote non-authenticated attacker can use a specially crafted X.509 certificate to bypass authentication process and gain unauthorized access to the application.
2) Resource exhaustion (CVE-ID: CVE-2023-33202)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing OpenSSL PEM encoded streams containing X.509 certificates. A remote attacker can send ASN.1 data through the PEMParser to trigger resource exhaustion and perform a denial of service (DoS) attack.
