Summary

CVE-2024-7580 is a medium-severity OS Command Injection (CWE-78) vulnerability in Alientechnology Alr-F800 Firmware. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 10.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

A vulnerability rated critical was identified in Alien Technology ALR-F800 devices running firmware up to version 19.10.24.00. The issue is an OS command injection flaw (CWE-78) residing in the /admin/system.html endpoint, where unsanitized input supplied to the uploadedFile argument can be abused to execute arbitrary operating system commands.

An authenticated remote attacker can exploit the flaw over the network by submitting a crafted payload such as ;whoami. Successful exploitation grants the ability to run commands on the underlying system, with the public proof-of-concept demonstrating direct command execution.

No vendor patch or mitigation guidance has been issued; the vendor was contacted prior to disclosure but did not respond. Public references consist of a proof-of-concept and vulnerability database entries that simply restate the reported details.

The associated EPSS score remains low, with a modest peak of 0.0620 followed by recession to the current value of 0.0466.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
T1202 Indirect Command Execution Stealth
Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters.
Why these techniques?

OS command injection via unauthenticated web interface (/admin/system.html) enables exploitation of public-facing application (T1190), indirect command execution (T1202 as noted in advisory), and Unix shell command execution (T1059.004) using shell metacharacters like ';whoami'.

Mitigating Controls

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.

addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
