Lifecycle Timeline
7DescriptionNVD
Sitecore Experience Manager (XM) and Experience Platform (XP) versions 10.1 to 10.1.4 rev. 011974 PRE, all versions of 10.2, 10.3 to 10.3.3 rev. 011967 PRE, and 10.4 to 10.4.1 rev. 011941 PRE contain a hardcoded user account. Unauthenticated and remote attackers can use this account to access administrative API over HTTP.
AnalysisAI
Sitecore Experience Manager (XM) and Experience Platform (XP) versions 10.1 through 10.4.1 contain a hardcoded administrative user account that allows unauthenticated remote attackers to gain unauthorized access to sensitive administrative APIs over HTTP without authentication. This vulnerability has a CVSS score of 7.5 (High) and enables confidentiality breach through direct API access; exploitation likelihood is high due to the low attack complexity and lack of authentication requirements.
Technical ContextAI
This vulnerability is rooted in CWE-798 (Use of Hard-Coded Credentials), a critical authentication bypass flaw. Sitecore XM and XP platforms embed a static credential (username/password combination) within the application codebase or configuration, likely in configuration files, source code, or compiled binaries. Affected CPE strings encompass: Sitecore Experience Manager 10.1.x, 10.2.x, 10.3.x, 10.4.x and Sitecore Experience Platform 10.1.x, 10.2.x, 10.3.x, 10.4.x. The hardcoded account bypasses standard authentication mechanisms entirely, allowing direct HTTP access to administrative REST/SOAP APIs that should be restricted to authenticated and authorized users. The vulnerability affects both XM (single-tenant) and XP (multi-tenant platform) deployments.
RemediationAI
Immediate actions: (1) Update to patched versions—Sitecore released patches addressing this CVE; consult Sitecore Release Notes and Security Bulletins at https://support.sitecore.com for exact patch versions (expected: rev. 011975+ for 10.1.x, rev. 011968+ for 10.3.x, rev. 011942+ for 10.4.x); (2) If patching is delayed, disable or restrict HTTP access to administrative APIs at the network/firewall level—ensure only HTTPS is accessible and restrict access by IP to trusted admin networks; (3) Rotate or disable the hardcoded administrative account immediately if credential details are known; (4) Audit API access logs for unauthorized administrative API calls using the hardcoded account credentials; (5) Implement Web Application Firewall (WAF) rules to block direct API calls without proper authentication headers; (6) Review Sitecore's official security advisory (expected CVE-2025-34509 bulletin) for detailed patch and rollback instructions.
