1) Link following (CVE-ID: CVE-2023-4759)
The vulnerability allows a remote attacker to overwrite files on the system.
The vulnerability exists due to an insecure link following. A remote attacker can place a specially crafted symbolic link into the repository, trick the victim into cloning it and overwrite arbitrary files on the system.
2) 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.
3) 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.
