CVE-2025-0364
CWE-288Published: February 4, 2025· Updated: Jun 17, 2026
Official Description
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.
Risk Analysis
BigAnt Server versions up to 5.6.06 allow unauthenticated attackers to register as administrators and subsequently execute arbitrary PHP code via the Cloud Storage Addin. This critical vulnerability is rated 9.8 and allows full system compromise without authentication.
No public exploit is currently known, and the vulnerability is not in the KEV catalog. It is remotely exploitable with low attack complexity.
Upgrade BigAnt Server to a version beyond 5.6.06 and disable unnecessary registration or add-in features until patched.
Technical Analysis
CVE-2025-0364 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
