Description

Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.

Security Summary

CVE-2025-1616 is a critical vulnerability in the FiberHome AN5506-01A ONU GPON RP2511 device, specifically affecting an unknown functionality within the Diagnosis component. The issue arises from OS command injection triggered by manipulating the Destination Address argument, classified under CWE-77 and CWE-78. It carries a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L) and was published on 2025-02-24.

The vulnerability can be exploited remotely by attackers who possess high privileges (PR:H) on the affected device, with low attack complexity and no requirement for user interaction. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, enabling arbitrary OS command execution through the injected Destination Address argument.

Advisories from VulDB indicate that the exploit has been publicly disclosed and is available for use, with references at https://vuldb.com/?ctiid.296606, https://vuldb.com/?id.296606, and https://vuldb.com/?submit.501483. The vendor was contacted early regarding the disclosure but provided no response, and no patches or specific mitigations are mentioned.

MITRE ATT&CK Enterprise Techniques

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.
attack.mitre.org →
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.
attack.mitre.org →
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.

Why these techniques?

OS command injection via the web Diagnosis 'Destination Address' parameter enables exploitation of public-facing application (T1190), indirect command execution through the diagnostic utility (T1202), and arbitrary command execution on the network device akin to CLI abuse (T1059.008).
