SB2025060243 - Splunk Universal Forwarder update for third-party components

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Improper authorization (CVE-ID: CVE-2024-45337)

The vulnerability allows a remote attacker to gain unauthorized access to the application.

The vulnerability exists due to improper authorization caused by improper usage of the ServerConfig.PublicKeyCallback callback. A remote attacker can bypass authorization in certain cases and gain access to the application.

2) Resource exhaustion (CVE-ID: CVE-2024-45338)

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 in several Parse functions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.

3) Insufficient verification of data authenticity (CVE-ID: CVE-2024-53259)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient verification of data authenticity when processing ICMP packets. A remote attacker can inject an ICMP Packet Too Large packet in the communication between the target host and the application and perform a denial of service (DoS) attack.

4) Resource exhaustion (CVE-ID: CVE-2024-28180)

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 decompressing JWE with Decrypt or DecryptMulti. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

5) Input validation error (CVE-ID: CVE-2024-24789)

The vulnerability allows a remote attacker to manipulate data.

The vulnerability exists due to insufficient validation of user-supplied input in archive/zip when handling zip archives. A remote attacker can create a zip file with content that will vary depending on the implementation reading the file.

6) Input validation error (CVE-ID: CVE-2024-24790)

The vulnerability allows a remote attacker to modify application behavior.

The vulnerability exists due to improper handling of IPv4-mapped IPv6 addresses in net/netip within multiple methods, e.g. IsPrivate, IsLoopback. The affected methods return false for addresses which would return true in their traditional IPv4 forms, leading to potential bypass of implemented security features.

7) Resource exhaustion (CVE-ID: CVE-2025-22869)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources within the ssh package when handling clients that complete the key exchange slowly, or not at all. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
