Top Highlights
- TP-Link warns that several Omada gateway models are affected by four critical security vulnerabilities, including one with a CVSS score of 9.3 that allows remote command execution.
- The most severe flaw (CVE-2025-6542) could enable unauthenticated attackers to execute arbitrary OS commands, potentially taking complete control of affected devices.
- Additional vulnerabilities (CVE-2025-7850, CVE-2025-7851, CVE-2025-6541) range from command injection to root access, with some exploitable by attackers with admin or authenticated access.
- TP-Link recommends users update device firmware and change passwords immediately to mitigate risks, as these vulnerabilities are commonly exploited by threat actors.
Underlying Problem
TP-Link has issued warnings about significant security vulnerabilities affecting its Omada gateway devices, impacting over a dozen models across the ER, G, and FR series. The company released firmware updates to address four critical and high-severity flaws that pose serious risks to affected systems. The most alarming vulnerability, CVE-2025-6542, with a high CVSS score of 9.3, allows remote attackers without authentication to execute arbitrary operating system commands, potentially granting them complete control over the device. Other vulnerabilities include CVE-2025-7850, which enables command injection through compromised admin web portal access, and CVE-2025-7851, that could let attackers gain root access, and CVE-2025-6541, exploitable by authenticated users for OS command execution. These issues have been identified by TP-Link and reported to customers, who are advised to update their firmware and change passwords promptly to mitigate the risk. The disclosure highlights the ongoing threats posed by cyber actors exploiting network device flaws, underscoring the importance of vigilant cybersecurity practices.
