CVE-2024-21833 is a high-severity vulnerability affecting multiple TP-Link products, specifically the Archer AX3000, AX5400, AXE75, Deco X50, and Deco XE200 firmware versions. This vulnerability allows a network-adjacent unauthenticated attacker with access to the device to execute arbitrary operating system commands. Given the potential for significant exploitation, organizations utilizing these devices should take immediate action to mitigate risks.
The CVSS score for this vulnerability is 8.8, which indicates a high severity level. The implications of this vulnerability are critical, as it poses risks of unauthorized access and control over affected devices. With the initial configuration allowing login only from LAN ports or Wi-Fi, the attack surface is primarily limited to users with network access, yet the risks remain significant.
Risk to organizations includes potential data breaches and unauthorized system modifications. Attackers may leverage this vulnerability to gain control over the device, leading to further network compromises. Organizations should prioritize patching immediately to protect their systems from these risks.
As of now, there is no known public exploit for this vulnerability, but the potential for exploitation exists due to the high exploitability score. Organizations must stay vigilant and ensure they apply any available patches as soon as they are released.
Vulnerability Details
This vulnerability allows an unauthenticated attacker to execute arbitrary OS commands due to improper input validation, categorized under CWE-78. The affected products include the Archer AX3000, AX5400, AXE75, Deco X50, and XE200, with a CVSS score of 8.8 indicating high severity.
Technical Analysis
The root cause of CVE-2024-21833 stems from improper input validation, allowing attackers to execute commands on the operating system. The attack vector is classified as adjacent network, implying that the attacker must have network access to the targeted device. The attack complexity is low, requiring no privileges or user interaction, which further amplifies the risk potential.
Risk & Impact Analysis
The real-world deployment risk related to this vulnerability is significant, as it allows for complete control over the affected devices by anyone with network access. This could lead to unauthorized data access, modification, and a breach of network integrity. Given the high CVSS score, organizations should assess their exposure and prioritize remediation actions in their patch cycle.
