CVE info copied to clipboard

Summary

Certain switch models from PLANET Technology lack proper access control in firmware upload and download functionality, allowing unauthenticated remote attackers to download and upload firmware and system configurations, ultimately gaining full control of the devices.

Impact

This vulnerability allows unauthenticated remote attackers to gain full control of affected PLANET Technology switch models. Attackers can download existing firmware and system configurations, potentially exposing sensitive information. They can also upload malicious firmware or altered configurations, compromising the integrity and functionality of the devices. This can lead to severe impacts on network security, including potential network disruptions, data theft, and use of the compromised switches as a foothold for further attacks within the network.

Exploitation

There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.

Patch

As of the current information provided, there is no mention of an available patch. The security team should check with PLANET Technology for any firmware updates or security advisories addressing this vulnerability.

Mitigation

1. Immediately restrict network access to the affected PLANET Technology switch models, especially from untrusted networks. 2. Implement strong network segmentation to isolate these switches from critical systems and the internet. 3. Monitor for any suspicious activities related to firmware updates or configuration changes on these devices. 4. If possible, disable remote firmware upload/download functionality until a patch is available. 5. Regularly backup switch configurations and store them securely off-device. 6. Implement additional authentication mechanisms, such as VPNs or jump hosts, for administrative access to these switches. 7. Keep an eye on PLANET Technology's security advisories for patches and follow their recommended upgrade procedures when available.

Vulnerability Summary for the Week of September 30, 2024
High Vulnerabilities Primary Vendor — Product Description Published CVSS Score Source & Patch Info n/a–n/a An issue was discovered in Atos Eviden iCare 2.7.1 through 2.7.11. The application exposes a web interface locally. In the worst-case scenario, if the application is remotely accessible, it allows an attacker to execute arbitrary commands with system privilege on the endpoint hosting the application, without any authentication. 2024-09-30 10 CVE-2024-42017 cve@mitre.org cve@mitre.org Cisco–Cisco Data Center Network Manager A vulnerability in the REST API and web UI of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to perform a command injection attack against an affected device. This vulnerability is due to improper user authorization and insufficient validation of command arguments. An attacker could exploit this vulnerability by submitting crafted commands to an affected REST API endpoint or through the web UI. A successful exploit could allow the attacker to execute arbitrary commands on the CLI of a Cisco NDFC-managed device with network-admin privileges. Note: This vulnerability does not affect Cisco NDFC when it is configured for storage area network (SAN) controller deployment. 2024-10-02 9.9 CVE-2024-20432 ykramarz@cisco.com n/a–n/a The WebDAV service in Infinera TNMS (Transcend Network Management System) 19.10.3 allows a low-privileged remote attacker to conduct unauthorized file operations, because of execution with unnecessary privileges.
