An authenticated remote code execution (RCE) vulnerability affects the TP-Link Archer router series. This vulnerability allows attackers to execute arbitrary code on the affected devices. It exists in the "tmp_get_sites" function of the HomeShield functionality provided by TP-Link. Notably, this vulnerability remains exploitable even without the activation of the HomeShield functionality.
The CVSS score for this vulnerability is 8, indicating a high-severity risk. This level of severity is critical for organizations using these routers, as it implies a significant threat that could be leveraged by attackers to compromise network integrity.
Risk to organizations includes potential unauthorized access and control over the affected devices, which could lead to data breaches or further attacks on the network. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Current exploitation status indicates that while no public exploits have been confirmed, the vulnerability is known within the security community. Security teams should remain vigilant and monitor for any indicators of exploitation.
Given the nature of this vulnerability and its potential impact, organizations using TP-Link Archer routers must act swiftly to implement necessary updates or mitigations.
Vulnerability Details
The vulnerability identified as CVE-2024-53375 presents a significant risk to the TP-Link Archer router series. Officially described as an authenticated remote code execution (RCE) vulnerability, it has a CVSS score of 8, classified as high severity. The vulnerability resides within the "tmp_get_sites" function of the HomeShield feature, which remains exploitable even when HomeShield is not activated.
Published on December 2, 2024, this vulnerability is categorized under CWE-78, which pertains to OS Command Injection. Organizations using the affected devices are encouraged to assess their exposure and implement remediation strategies promptly.
Technical Analysis
The root cause of CVE-2024-53375 lies in improper handling of user-supplied input within the "tmp_get_sites" function. This oversight allows attackers on the adjacent network to send crafted requests that can lead to code execution.
The attack vector is classified as adjacent network, meaning that an attacker must be on the same local network to exploit this vulnerability. The attack complexity is low, as it requires only low privileges and no user interaction, increasing the risk of successful exploitation.
The impacts of this vulnerability are severe, with high implications for confidentiality, integrity, and availability. Organizations must understand that successful exploitation could lead to unauthorized access and control over network devices, compromising sensitive data and disrupting service.
Risk & Impact Analysis
Real-world deployment of affected TP-Link Archer routers poses significant risks. Attackers may leverage this vulnerability to gain control over network devices, potentially leading to a broader compromise of organizational resources and sensitive information. The blast radius is extensive, as routers often serve as critical nodes in network infrastructure.
Organizations should assess their use of affected products and prioritize remediation based on the high CVSS score. Given the urgent nature of this vulnerability, immediate action is warranted to prevent potential exploitation in the wild.
