CVE-2025-0364

CVSS v3.1

9.8

Critical

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions BigAntSoft BigAnt Server versions up to and including 5.6.06
Description The issue concerns 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.
Recommendations For BigAntSoft BigAnt Server versions up to and including 5.6.06, consider disabling the "Cloud Storage Addin" to prevent the execution of arbitrary PHP code until a patch is available. Restrict access to the account registration mechanism to minimize the risk of exploitation. Avoid using the default exposed SaaS registration mechanism until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
