Description
This security bulletin contains information about 6 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) Input validation error (CVE-ID: CVE-2023-20863)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2023-34462)
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 if no idle timeout handler was configured. A remote attacker can send a client hello packet, which leads the server to buffer up to 16MB of data per connection and results in a denial of service condition.
4) Incorrect default permissions (CVE-ID: CVE-2023-2976)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions in com.google.common.io.FileBackedOutputStream. A local user with access to the system can view contents of files and directories or modify them.
5) Input validation error (CVE-ID: CVE-2022-41966)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote attacker can pass specially crafted data to the application, trigger a stack overflow error and perform a denial of service (DoS) attack.
6) Stack-based buffer overflow (CVE-ID: CVE-2022-45688)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists in the XML.toJSONObject component. A remote unauthenticated attacker can send a specially crafted JSON or XML data, trigger stack-based buffer overflow and perform a denial of service attack.
