CVE-2025-0364: BigAntSoft BigAnt Server Account Registration Bypass to File Upload RCE

Noroxi assessment

Priority: Plan (action score 40/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.9% (FIRST EPSS); higher than 79.9% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
