# CVE-2024-38529: Admidio Vulnerable to RCE via Arbitrary File Upload in Message Attachment

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.2% , percentile 69: FIRST’s model estimates a 1.2% chance of exploitation activity in the next 30 days, higher than 69% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes admidio/admidio (Composer (PHP)) < 4.3.10, fixed in 4.3.10 . Check your lockfile, including transitive dependencies.

## What it is

Admidio is a free, open source user management system for websites of organizations and groups. In Admidio before version 4.3.10, there is a Remote Code Execution Vulnerability in the Message module of the Admidio Application, where it is possible to upload a PHP file in the attachment. The uploaded file can be accessed publicly through the URL {admidiobaseurl}/admmyfiles/messagesattachments/{filename}. The vulnerability is caused due to the lack of file extension verification, allowing malicious files to be uploaded to the server and public availability of the uploaded file. This vulnerability is fixed in 4.3.10.

## Affected packages

- Composer (PHP) `admidio/admidio` < 4.3.10 → fixed: 4.3.10

## Affected products (CVE record)

- Admidio admidio: < 4.3.10

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 1.24% probability of exploitation activity in the next 30 days; percentile 69.
