SB2025103055 - Splunk AppDynamics Machine Agent update for third-party components

Description

This security bulletin contains information about 3 vulnerabilities.

1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2024-6763)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:U/U:Green

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in HttpURI. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

2) Inadequate Encryption Strength (CVE-ID: CVE-2022-3358)

CWE-ID: CWE-326 - Inadequate Encryption Strength

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:A/U:Green

The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to an error in openssl implementation when handling legacy custom ciphers with NID_undef passed to the EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() and EVP_CipherInit_ex2() functions. Under certain conditions openssl can fail to select a proper cipher and use NULL instead, which corresponds to sending data in plain text.

Note, applications are only affected by this issue if they call EVP_CIPHER_meth_new() using NID_undef and subsequently use it in a call to an encryption/decryption initialisation function.

3) Resource exhaustion (CVE-ID: CVE-2025-48976)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green

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

The vulnerability exists due to Apache Commons FileUpload provided a hard-coded limit of 10kB for the size of the headers associated with a multipart request. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
