RCE in Asgaros Forum ≤ 2.7.1
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-5604 is a critical-severity Code Injection (CWE-94) vulnerability in Asgaros Asgaros Forum. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 20% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The Asgaros Forum WordPress plugin before version 2.7.1 is affected by a configuration weakness that permits forum administrators, who lack full WordPress super-administrator privileges, to enable uploads of dangerous file types such as .php and .phtml. This stems from improper handling of allowed file extensions and is tracked under CWE-94 and CWE-434, resulting in a CVSS 3.1 score of 9.8.
Forum administrators can exploit the flaw by altering plugin settings to permit these uploads, after which any unauthenticated remote attacker can upload and execute arbitrary code on the server without authentication or user interaction.
Public references point to WPScan advisories that document the issue in the affected plugin versions and indicate that the vulnerability is resolved in the 2.7.1 release.
The associated EPSS score remains at 0.0699 with no material increase observed after disclosure.

Vulnerability Data
The Asgaros Forum WordPress plugin before 2.7.1 allows forum administrators, who may not be WordPress (super-)administrators, to set insecure configuration that allows unauthenticated users to upload dangerous files (e.g. .php, .phtml), potentially leading to remote code execution.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
Hardened configuration baselines can enforce allowed file types and processing rules.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
