Critical GoLang x/crypto Vulnerability
The security advisory identifies multiple critical and high-severity vulnerabilities requiring immediate attention.
The most critical vulnerability, CVE-2024-45337 with a severity rating of “Critical,” affects golang.org/x/crypto in the spl2-orchestrator component.
This flaw represents a high-severity in the cryptographic implementations used by Go applications, potentially allowing attackers to compromise encrypted communications or bypass security controls.
The vulnerability specifically impacts applications that utilize the golang.org/x/crypto package for cryptographic operations, including encryption, decryption, and secure key management.
In the context of Splunk Enterprise, this CVE affects the spl2-orchestrator component, which handles orchestration tasks within the Splunk platform.
High-Severity Flaws in Setuptools, GoLang, and Libcurl
High-severity vulnerabilities include CVE-2024-6345 in setuptools, CVE-2025-22869 in golang.org/x/crypto identity component, and multiple CVEs affecting golang packages in Mongodump and Mongorestore utilities.
The libcurl package presents particularly concerning exposure, with upgrades addressing ten separate CVEs, including CVE-2024-0853, CVE-2024-2398, CVE-2024-2466, CVE-2024-7264, CVE-2024-8096, CVE-2024-9681, CVE-2024-11053, CVE-2025-0167, and CVE-2025-0725.
