CVE-2025-0364: CWE-288 Authentication Bypass Using an Alternate Path or Channel in BigAntSoft BigAnt Server
BigAntSoft BigAnt Server, up to and including version 5.6.06, is vulnerable to unauthenticated remote code execution via account registration. An unauthenticated remote attacker can create an administrative user through the default exposed SaaS registration mechanism. Once an administrator, the attacker can upload and execute arbitrary PHP code using the "Cloud Storage Addin," leading to unauthenticated code execution.
AI Analysis
Technical Summary
CVE-2025-0364 is a critical vulnerability in BigAntSoft BigAnt Server (up to version 5.6.06) involving CWE-288 (Authentication Bypass Using an Alternate Path or Channel). The flaw allows unauthenticated remote attackers to create an administrative account through the exposed SaaS registration feature. With administrative privileges, attackers can leverage the Cloud Storage Addin to upload and execute arbitrary PHP code remotely without authentication, leading to full system compromise. The CVSS 3.1 base score is 9.8, reflecting the high impact and ease of exploitation.
Potential Impact
Successful exploitation results in unauthenticated remote code execution with administrative privileges, allowing attackers to fully compromise the affected server. Confidentiality, integrity, and availability of the system are severely impacted. No known exploits in the wild have been reported yet.
Mitigation Recommendations
No official patch or fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, it is recommended to disable or restrict access to the SaaS registration mechanism and the Cloud Storage Addin to prevent unauthorized account creation and code execution.
