Vulnerability Details
The vulnerability affects the WAVLINK WN535K2 and WN535K3 devices, particularly the firmware versions. The CVE-2022-2488 was published on July 20, 2022, and has been classified under CWE-78, which represents OS command injection vulnerabilities.
The following CVSS score details are available:
Metric | Value |
|---|---|
CVSS Version | 3.1 |
Attack Vector | Adjacent Network |
Privileges Required | Low |
Confidentiality Impact | High |
Integrity Impact | High |
Availability Impact | High |
Technical Analysis
The root cause of this vulnerability is improper input validation in the processing of command line parameters, specifically the IP argument within the affected CGI file. This oversight allows attackers to execute arbitrary commands, leveraging the vulnerable function to interact with the underlying operating system.
The attack vector is adjacent network, meaning that an attacker must be on the same local network to exploit this vulnerability. The complexity of the attack is considered low, with little effort required to successfully execute the command injection.
No user interaction is required to exploit this vulnerability, further increasing its risk profile. The impacts on confidentiality, integrity, and availability are all rated as high, indicating that successful exploits could lead to significant negative consequences for affected systems.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-2488 is considerable. Given that the vulnerability allows for command injection, attackers may leverage this flaw to gain unauthorized access to the system, potentially leading to a full system compromise.
The blast radius for organizations using these affected WAVLINK products could be extensive, as the exploitation could lead to breaches of sensitive data and disruption of services. Therefore, organizations should prioritize patching immediately.
The urgency for remediation is underscored by the high CVSS score of 9.8 from NVD. Organizations should address this vulnerability in their priority patch cycle, ensuring that all affected products are updated with the necessary security patches.
