A vulnerability has been found in Shenzhen Libituo Technology LBT-T300-HW1 up to 1.2.8. The function start_lan of the file /apply.cgi is affected. The manipulation of the argument Channel/ApCliSsid leads to buffer overflow. This vulnerability allows the exploitation to be carried out remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The CVSS score for this vulnerability is 7.4, categorized as high severity. Organizations should prioritize patching immediately to mitigate potential risks. Given the nature of the vulnerability, attackers may leverage this flaw to execute arbitrary code or disrupt service.
Risk to organizations includes unauthorized access and potential data loss due to the buffer overflow condition. The vulnerability's impact is significant, making it essential for affected users to address it without delay.
The urgency for defenders is high, as the exploit has been made public and could be used by malicious actors. Organizations are advised to take immediate action to secure their systems.
Vulnerability Details
The vulnerability, classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input), poses significant threats to confidentiality, integrity, and availability, all rated high.
The CVSS version 4.0 vector indicates that the attack vector is network-based, with low attack complexity, and requires low privileges. No user interaction is required for the attack to succeed.
The exploit maturity is currently at 'proof of concept', indicating that while there may not be widespread exploitation, the potential for attack exists.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input parameters, which leads to a buffer overflow condition. Remote attackers can exploit this flaw by sending specially crafted requests to the vulnerable function.
The attack vector is network-based, allowing attackers to target devices over the internet without physical access. The attack complexity is low, meaning that minimal effort is required to exploit the vulnerability.
The privileges required to execute the attack are low, which means that even an authenticated user could potentially trigger the exploit. User interaction is not required, enhancing the risk.
The impacts on confidentiality, integrity, and availability are rated high, indicating that successful exploitation could lead to severe disruption and loss of sensitive data.
Risk & Impact Analysis
Organizations utilizing the affected devices face substantial risks. The potential for unauthorized access and system compromise is significant. The blast radius could extend to critical infrastructure if exploited.
Given the high CVSS score and the current vulnerability status, organizations should address this vulnerability in their priority patch cycle. The urgency is heightened by the public disclosure of the exploit.
Organizations should schedule remediation efforts immediately, as the potential for exploitation is real and present in the wild.
