Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-4639)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of cookies with certain value-delimiting characters in incoming requests. A remote attacker can construct a cookie value to exfiltrate HttpOnly cookie values or spoof arbitrary additional cookie values, leading to unauthorized data access or modification.
2) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
3) Resource exhaustion (CVE-ID: CVE-2023-1973)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to server does not properly control consumption of internal resources when handling HTTP requests. A remote attacker can send specially crafted HTTP requests to the server to trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Resource exhaustion (CVE-ID: CVE-2024-1635)
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 handling rapidly open and closed HTTP connections. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2023-3223)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources by servlets annotated with @MultipartConfig. A remote attacker can send a large multipart content to the server, consume all available memory resources and perform a denial of service (DoS) attack.
