CVE-2025-58443 — FOG's authentication bypass leads to full SQL DB dump

FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Versions 1.5.10.1673 and below contain an authentication bypass vulnerability. It is possible for an attacker to perform an unauthenticated DB dump where they could pull a full SQL DB without credentials. A fix is expected to be released 9/15/2025. To address this vulnerability immediately, upgrade to the latest version of either the dev-branch or working-1.6 branch. This will patch the issue for users concerned about immediate exposure. See the FOG Project documentation for step-by-step upgrade instructions: https://docs.fogproject.org/en/latest/install-fog-server#choosing-a-fog-version.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

How the score was calculated

Public exploit/PoC (nuclei)+4
EPSS 19.4% (30-day exploitation probability)+15
Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Fogproject Fogproject).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
EPSS ahead of 97% of scored CVEs: prioritize it in the patch queue.
Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

Public exploits, PoCs and detection templates

Public code that demonstrates or tests the flaw raises the odds of mass exploitation — and Nuclei templates help find vulnerable assets in your environment.

What should defenders know first?

CVE-2025-58443 is "FOG's authentication bypass leads to full SQL DB dump", rated Critical. It affects Fogproject (Fogproject); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 9.1 describes technical severity. EPSS 19.41% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
