Description
Anevia Flamingo XL 3.2.9 contains a restricted shell vulnerability that allows remote attackers to escape the sandboxed environment through the traceroute command. Attackers can exploit the traceroute command to inject shell commands and gain full root access to the device by bypassing the restricted login environment.
AI Analyst Comment
Remediation
Update Anevia Flamingo XL Multiple Products to the latest version. Monitor for exploitation attempts and review access logs.
Executive Summary:
A critical vulnerability has been identified in Anevia Flamingo XL products, assigned CVE-2024-58338 with a CVSS score of 9.8. This flaw allows a remote attacker to escape a restricted user environment by manipulating the
traceroutecommand, leading to a complete system takeover with root-level privileges. Successful exploitation could result in total compromise of the affected device, service disruption, and unauthorized access to the network.Vulnerability Details
CVE-ID: CVE-2024-58338
Affected Software: Anevia Flamingo XL Multiple Products
Affected Versions: Version 3.2.9 is confirmed to be vulnerable. See vendor advisory for a complete list of affected versions.
Vulnerability: The vulnerability is a restricted shell escape due to improper input validation in the
traceroutecommand. An attacker with access to the device's restricted shell can inject arbitrary shell commands as arguments to thetracerouteutility. Because the input is not properly sanitized, these injected commands are executed by the underlying operating system with elevated privileges, bypassing the intended sandbox restrictions and resulting in full root access to the device.Business Impact
This vulnerability is rated as critical severity with a CVSS score of 9.8, indicating a high risk of exploitation and severe potential impact. A successful attack would grant an adversary complete control over the affected Anevia Flamingo XL device. This could lead to significant business consequences, including the theft of sensitive data, disruption of critical video streaming services, installation of persistent malware or backdoors, and using the compromised device as a pivot point to launch further attacks against the internal network. The potential for reputational damage and financial loss is substantial.
Remediation Plan
Immediate Action: Immediately apply the security patches provided by the vendor. Update all Anevia Flamingo XL Multiple Products to the latest recommended version to mitigate this vulnerability. In parallel, initiate a review of all system and access logs for any signs of compromise or suspicious activity related to the
traceroutecommand.Proactive Monitoring: Implement enhanced monitoring on affected devices. Security teams should look for unusual usage of the
traceroutecommand in shell logs, especially those containing special characters or chained commands (e.g.,;,|,&&). Monitor for unexpected outbound network connections, unauthorized processes running with root privileges, and any unauthorized file modifications on the system.Compensating Controls: If immediate patching is not feasible, implement the following compensating controls:
traceroutecommand for restricted user accounts or further limit the permissions of the shell environment.Exploitation Status
Public Exploit Available: false
Analyst Notes: As of Dec 30, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, due to the critical severity and the straightforward nature of shell escape vulnerabilities, it is highly probable that proof-of-concept exploits will be developed and weaponized by threat actors. The vulnerability is not currently listed on CISA's Known Exploited Vulnerabilities (KEV) catalog.
Analyst Recommendation
Given the critical CVSS score of 9.8, this vulnerability presents an immediate and severe threat to the organization. We strongly recommend that all affected Anevia Flamingo XL devices be patched on an emergency basis. Although there is no evidence of active exploitation at this time, the risk of a full system compromise is too significant to delay remediation. If patching cannot be performed immediately, apply the recommended compensating controls and prioritize these systems for the next available maintenance window.
