CVE-2025-67737 — AzuraCast Vulnerable to Pre-Auth File Deletion & Admin RCE

AzuraCast is a self-hosted, all-in-one web radio management suite. Versions 0.23.1 mistakenly include an API endpoint that is intended for internal use by the SFTP software sftpgo, exposing it to the public-facing HTTP API for AzuraCast installations. A user with specific internal knowledge of a station's operations can craft a custom HTTP request that would affect the contents of a station's database, without revealing any internal information about the station. In order to carry out an attack, a malicious user would need to know a valid SFTP station username and the coordinating internal filesystem structure. This issue is fixed in version 0.23.2.

Who exploits it and how urgent it is

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

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2

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

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

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

  • Documented patch — github.com (NIST National Vulnerability Database)
  • Composer Azuracast/azuracast: fixed in version 0.23.2 — github.com (GitHub Security Advisories)

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.

  1. Identify exposed assets running the affected vendor/product/version combinations (Azuracast Azuracast, Composer Azuracast/azuracast).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. Apply the fixed version or the patch documented under Remediation.
  4. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.

What should defenders know first?

CVE-2025-67737 is "AzuraCast Vulnerable to Pre-Auth File Deletion & Admin RCE", rated Low. It affects Azuracast (Azuracast); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 3.7 describes technical severity. EPSS 0.25% 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.
