SB2025073180 - Splunk Enterprise Security update for third-party components

Description

This security bulletin contains information about 6 vulnerabilities.

1) Open redirect (CVE-ID: CVE-2022-33987)

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

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

The vulnerability allows a remote attacker to redirect victims to arbitrary URL.

The vulnerability exists due to requested URLs are not verified and allow open redirection to a local UNIX socket. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.

Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.

2) Prototype pollution (CVE-ID: CVE-2025-25977)

CWE-ID: CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes (\'Prototype Pollution\')

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

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation. A remote attacker can execute arbitrary code via the Constructor of the class StyleElement.

3) Improper verification of cryptographic signature (CVE-ID: CVE-2024-48948)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

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

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

The vulnerability exists due to incorrect validation of valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. Such behavior leads to valid signatures being rejected.

4) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42459)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

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

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error when handling EDDSA signatures. A remote attacker can bypass signature-based security checks.

5) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42461)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

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

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error when handling BER-encoded ECDSA signatures. A remote attacker can bypass signature-based security checks.

6) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2024-42460)

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

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

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error when handling ECDSA signatures. A remote attacker can bypass signature-based security checks.
